The numbers can be represented as [tex]x[/tex] and [tex]x+1[/tex].
We know that [tex]x+x+1=1107[/tex].
Combine like terms. [tex]2x+1=1107[/tex]
Subtract 1 on both sides. [tex]2x=1106[/tex]
Divide both sides by 2. [tex]x=553[/tex]
The first number is [tex]x[/tex], which equals [tex]\boxed{553}[/tex].
The second number is [tex]x+1[/tex], which equals [tex]553+1[/tex], which is [tex]\boxed{554}[/tex].
These numbers can be presented as n and n + 1 = 1107
2n = 1106 because we combine the n terms and subtract 1 from each side.
2n ÷ 2 = n
1106 ÷ 2 = 553
We now know that n = 553.
Our second consecutive integer must be 554. This is because our second
consecutive integer represents n + 1 so 553 + 1 =554.
Therefore, are two consecutive integers are 553 and 554.

The length of a rectangle is equal to triple the width.
Find the width of the rectangle if the perimeter is 80 centimeters.
Answer:
10 cm
Step-by-step explanation:
If the length of a rectangle is equal to triple the width, the width of the rectangle is 10 cm if the perimeter is 80 centimeters.
L = 3w
P = 80
Formula: a = l × w
8W = 80 cm
W = 80 / 8 = 10 cm
Therefore, the width of the rectangle is 10 centimeters.
The width of the rectangle is found to be 10 centimeters, obtained by solving the equation created based on the fact that the perimeter of a rectangle is 2(length + width) and the given data that length is thrice the width and perimeter is 80 cm.
Explanation:To figure out the width of the rectangle, we first need to understand the relationship between the length and width, and how they relate to the perimeter. The length of the rectangle is triple the width. Let's define the width as 'w'. Therefore, the length would be '3w'.
The formula for the perimeter of a rectangle is 2(length + width).
Given that the perimeter is 80 centimeters, we can set up the equation 2(3w + w) = 80. Simplifying this gives 8w = 80. To find the width 'w', we divide both sides of the equation by 8, giving us w = 10 centimeters.
Therefore, the width of the rectangle is 10 centimeters.

what is the equation of the line that passes through the points (4/5,1/5) and (1/2,3/2)?
Answer:
[tex]y-\frac{3}{2}=\frac{-13}{3}(x-\frac{1}{2})[/tex] point-slope form
[tex]13x+3y=11[/tex] (standard form)
Let me know if you prefer another form.
Step-by-step explanation:
The slope of a line can be found using [tex]\frac{y_2-y_1}{x_2-x_1}[/tex] provided you are given two points on the line.
We are.
Now you can use that formula. But I really love to just line up the points vertically then subtract them vertically then put 2nd difference over 1st difference.
(4/5 , 1/5)
-( 1/2 , 3/2)
-----------------
3/10 -13/10
2nd/1st = [tex]\frac{\frac{-13}{10}}{\frac{3}{10}}=\frac{-13}{3}[/tex] is our slope.
So the following is point-slope form for a linear equaiton:
[tex]y-y_1=m(x-x_1) \text{ where } m \text{ is slope and } (x_1,y_1) \text{ is a point on the line }[/tex]
Plug in a point [tex](x_1,y_1)=(\frac{1}{2},\frac{3}{2}) \text{ and } m=\frac{-13}{3}[/tex].
This gives:
[tex]y-\frac{3}{2}=\frac{-13}{3}(x-\frac{1}{2})[/tex]
I'm going to distribute:
[tex]y-\frac{3}{2}=\frac{-13}{3}x-\frac{-13}{6}[/tex]
Now I don't like these fractions so I'm going to multiply both sides by the least common multiply of 2,3, and 6 which is 6:
[tex]6y-9=-26x+13[/tex]
Add 26x on both sides:
[tex]26x+6y-9=13[/tex]
Add 9 on both sides:
[tex]26x+6y=22[/tex] This is actually standard form of a line.
It can be simplified though.
Divide both sides by 2:
[tex]13x+3y=11[/tex] (standard form)
Answer:
[tex]\large\boxed{y=-\dfrac{13}{3}x+\dfrac{11}{3}}-\bold{slope\ intercept\ form}\\\boxed{13x+3y=11}-\bold{standard\ form}[/tex]
Step-by-step explanation:
The slope-intercept form of an equation of a line:
[tex]y=mx+b[/tex]
m - slope
b - y-intercept
The formula of a slope:
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
We have two points
[tex]\left(\dfrac{4}{5},\ \dfrac{1}{5}\right),\ \left(\dfrac{1}{2},\ \dfrac{3}{2}\right)[/tex]
Convert fractions to the decimals
(divide the numerator by the denominator) :
[tex]\dfrac{4}{5}=0.8,\ \dfrac{1}{5}=0.2,\ \dfrac{1}{2}=0.5,\ \dfrac{3}{2}=1.5[/tex]
[tex]\left(\dfrac{4}{5},\ \dfrac{1}{5}\right)=(0.8,\ 0.2)\\\\\left(\dfrac{1}{2},\ \dfrac{3}{2}\right)=(0.5,\ 1.5)[/tex]
Calculate the slope:
[tex]m=\dfrac{1.5-0.2}{0.5-0.8}=\dfrac{1.3}{-0.3}=-\dfrac{13}{3}[/tex]
Put the value of slope and the coordinates of the first point to the equation of a line:
[tex]0.2=-\dfrac{13}{3}(0.8)+b[/tex] multiply both sides by 3
[tex]0.6=(-13)(0.8)+3b[/tex]
[tex]0.6=-10.4+3b[/tex] add 10.4 to both sides
[tex]11=3b[/tex] divide both sides by 3
[tex]\dfrac{11}{3}=b\to b=\dfrac{11}{3}[/tex]
Finally:
[tex]y=-\dfrac{13}{3}x+\dfrac{11}{3}[/tex] - slope-intercept form
Convert to the standard form (Ax + By = C):
[tex]y=-\dfrac{13}{3}x+\dfrac{11}{3}[/tex] multiply both sides by 3
[tex]3y=-13x+11[/tex] add 13x to both sides
[tex]13x+3y=11[/tex] - standard form
Find the value of x and y.
A) x=12, y=10
B) x=14, y=11
C) x=14, y=10
D) x=12, y=11
This is for Geometry.
Answer:
The correct answer is first option
x = 12, y = 10
Step-by-step explanation:
From the figure we can see that a triangle ADC, and EB is parallel to side DC.
To find the value pf x
From the given figure we get,
<ABC = <BCD [ corresponding angles are equal]
3x + 9 = 4x - 3
4x - 3x = 9 + 3
x = 12
To find the value of y
<ABE and <EBC are linear pairs.
Therefore, <ABE + <EBC = 180
(3x + 9) + (14y - 5) = 180
(3 * 12 + 9) + 14y - 5 = 180
45 + 14y - 5 = 180
14y = 180 -40
14y = 140
y = 140/14 = 10
y = 10
Therefore x = 12 and y = 10

which binomials are a difference of squares? choose exactly two correct answers.
Answer:
B and C
Step-by-step explanation:
There are 3 conditions for the difference of squares.
The power on the variable must be even making A incorrect. x^2 - 16 is and example of what I mean. The 2 is even.The sign between 2 terms must be minus, making D incorrect.Any coefficient (given your examples) must be perfect squares. 9x^2 - 16. Nine and 16 are both perfect squares.The correct answer is B and C
Final answer:
Binomials that are a difference of squares have the form a² - b² and can be factored into (a + b)(a - b), where both terms are perfect squares. Examples include x² - 9 and 4y² - 25.
Explanation:
To determine which binomials are a difference of squares, we look for expressions in the form of a2 - b2. A difference of squares can be factored into (a + b)(a - b), where a and b are any expressions. It is essential that both terms be perfect squares and that they are subtracted from one another.
For example, x2 - 9 is a difference of squares as it can be factored into (x + 3)(x - 3), where both x2 and 9 are perfect squares. Another example could be 4y2 - 25, which factors to (2y + 5)(2y - 5). Keep in mind that if the sign is not subtraction, or if either term is not a perfect square, the binomial does not represent a difference of squares. The correct choice of examples, factoring process, and the nature of perfect squares are essential to identify differences of squares accurately.

We have to break the middle term:
If we multiply 81 by 16 we get 1296:
The same answer we get when we multiply 36 by 36:
36*36=1296
And if we add 36+36 then we get the middle term which is 72.
So,
=81x²+72x+16
=81x²+36x+36x+16
=9x(9x+4)+4(9x+4)
=(9x+4)(9x+4)

A triangular field has sides 218.5 and 213.3 and the angle between them measures 58.96°. Find the area of the field.
Answer:
The area of the field = 19966.21 units²
Step-by-step explanation:
* Lets explain how to find area of a triangle by trigonometry rule
- In any triangle if you have the lengths of two sides and the measure
of the including angle between these two sides, then the area of the
triangle is A = [tex]\frac{1}{2}s_{1}s_{2}sin\alpha[/tex] , wher α is the
including angle between them
* Lets solve the problem
∵ The field is shaped triangle
∵ The lengths of two sides of the field are 218.5 and 213.3
∴ s1 = 218.5
∴ s2 = 213.3
∵ The measure of the angle between the two sides is 58.96°
∴ α = 58.96°
- Lets find the area using the rule of trigonometry
∴ [tex]A=\frac{1}{2}(218.5)(213.3)sin(58.96)=19966.21[/tex]
∴ The area of the field = 19966.21 units²

If a circle has diameter endpoints at (-1,7) and (6,2), what is its center and radius
Answer:
The radius is [tex]\frac{\sqrt{74}}{2}[/tex].
The center is (5/2 , 9/2).
Step-by-step explanation:
The radius is half the diameter. We aren't given the length of the diameter but we are given endpoints to one of them.
So let's find the length of that diameter using the distance formula.
The distance formula is
[tex]d=\sqrt{(x_1-x_2)^2+(y_1-y_2)^2}[/tex].
I just do big x minus small x or big y minus small y.
Anyways the points are (-1,7) and (6,2).
The x distance is 6-(-1)=7.
The y distance is 7-2=5.
So we have this using the distance formula so far:
[tex]d=\sqrt{(6-(-1))^2{(7-2)^2}[/tex]
[tex]d=\sqrt{7^2+5^2}[/tex]
[tex]d=\sqrt{49+25}[/tex]
[tex]d=\sqrt{74}[/tex]
So the radius is half that much because that was the distance between the endpoints of a diameter.
So the radius is [tex]\frac{\sqrt{74}}{2}[/tex].
Now the center of a circle will lie on the midpoint of a diameter, any given diameter.
We have the endpoints of one, so we just need to use midpoint formula.
Midpoint formula says the midpoint is (average of x, average y).
Midpoint formula: [tex](\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})[/tex].
So average of x's is (-1+6)/2=5/2.
The average of y's is (7+2)/2=9/2.
So the midpoint of the diameter or the center of the circle is at (5/2 , 9/2).

A white tailed deer can sprint at speeds up to 30 miles per hour. American bison can run at speeds up to 3,520 feet per minute. Which animal is faster and by how many per hour? There are 5,280 feet in one mile
Answer:
American Bison
Step-by-step explanation:
First find out how many feet the bison runs in an hour.
To find that out you have to multiply 3520 by 60 minutes because there are 60 minutes in an hour.
So 3520*60 = 211,200 feet
Then you have to convert 211,200 feet into miles and since there are 5,280 feet in an a mile you have to divide.
So 211,200 divided by 5,280 = 40
So the American Bison runs 40 miles per hour which is faster than the White Tailed Deer who only runs 30 miles per hour.
So the answer is the American Bison.

Suppose that the functions g and h are defined for all real numbers x as follows.
g(x) = 4x– 4
h(x) = x-5
Write the expressions for (g+h)(x) and (g-h)(x) and evaluate (g.h)(1).
Answer:
See below in bold.
Step-by-step explanation:
(g + h)(x) = 4x - 4 + x - 5
= 5x - 9.
(g - h)(x) = 4x - 4 - (x - 5) ( Note we put the x - 5 in parentheses)
= 4x - 4 - x + 5
= 3x + 1.
(g.h)(x) = (4x - 4)(x - 5)
so (g.h)(1) = (4(1) - 4)(1 - 5)
= 0 * -4
= 0.
The product of the functions will be (g·h)(x) = 4x² – 24x + 20. At x = 1, the product of the functions is zero.
What is a function?A statement, principle, or policy that creates the link between two variables is known as a function.
The functions are given below.
g(x) = 4x – 4
h(x) = x – 5
Then the sum of the functions will be
(g + h)(x) = (4x – 4) + (x – 5)
(g + h)(x) = 4x – 4 + x – 5
(g + h)(x) = 5x – 9
Then the difference in the functions will be
(g – h)(x) = (4x – 4) – (x – 5)
(g – h)(x) = 4x – 4 – x + 5
(g – h)(x) = 3x + 1
Then the product of the functions will be
(g·h)(x) = (4x – 4)(x – 5)
(g·h)(x) = 4x² – 4x – 20x + 20
(g·h)(x) = 4x² – 24x + 20
At x = 1, then we have
(g·h)(x) = 4(1)² – 24(1) + 20
(g·h)(x) = 4 - 24 + 20
(g·h)(x) = 0

Name 3 ways that a parabola changes with different types of "a" values.
Answer:
Up down and side to side on the graph
Step-by-step explanation:
If a is 1, since it is positive the parabola moves up. If a is -1, since it is negative the parabola moves down. (not sure about side to side because I can't back that one up but I'm 100% sure about up and down)
When a is between 0 and 1, the parabola gets wider.
What is the parabola?A parabola is a mathematical curve that is defined by a point and a line. The point is known as the focus, and the line is called the directrix. The parabola has the property that all points on it are equidistant from the focus and the directrix.
Here,
When a is negative, the parabola flips 180°.
When |a| is less than 1, the parabola opens wider.
When |a| is greater than 1, the parabola opens more narrow.
When a is between 0 and 1, the parabola gets wider, when it is greater than 1, it gets narrower, and when it is less than 0 it is reflected across the x-axis.
Therefore, when a is between 0 and 1, the parabola gets wider.

Answer:
C; The left end goes up; the right end goes down
Step-by-step explanation:
If you expand the function, you end up with a polynomial with a negative coefficient and it has an odd power. According to polynomial behaviors of a function that is odd negative, the graph will rise to the left (y → ∞ and x → -∞) and falls to the right (y → -∞ and x → ∞).
ANSWER
C. The left end goes up; the right end goes down.
EXPLANATION
The given function is
[tex]f(x) = - 2( {x - 2)}^{5} [/tex]
We analyze the end behavior of this function using the leading term.
The leading term of this function is:
[tex] - 2 {x}^{5} [/tex]
Since the degree(5) is odd and the leading coefficient (-2) is negative, the graph rises on the left and falls on the right.
In other words, the left end of the graph goes up and the right end goes down.
The correct option is C.

Mr. Wilson is building a swimming pool in his backyard. The width of the pool is twice the depth and the length of the pool is 3 feet
longer than the width.
Which of the following statements is true?
The monomial 3d represents the length of the swimming pool.
The trinomial 2d3 +3d2+1 represents the volume of the swimming pool.
The binomial 6d3 + 4d2 represents the volume of the swimming pool.
The binomial 2d + 3 represents the length of the swimming pool.
Answer:
The binomial 2d + 3 represents the length of the swimming pool
Step-by-step explanation:
Let
l ----> the length of the swimming pool
w ---> the with of the swimming pool
d ---> the depth of the swimming pool
we know that
[tex]w=2d[/tex] -----> equation A
[tex]l=w+3[/tex] ----> equation B
substitute equation A in equation B
[tex]l=2d+3[/tex] -----> equation C
The volume of the swimming pool is equal to
[tex]V=lwd[/tex]
Substitute equation A and equation C in the formula of Volume
[tex]V=(2d+3)(2d)d\\ \\ V=4d^{3}+6d^{2}[/tex]
therefore
The binomial 2d + 3 represents the length of the swimming pool (equation C)
A given line has the equation 10x - 2y=-2.
What is the equation, in slope-intercept form, of the line that is parallel to the given line and passes through the point (0, 12)?
y= -5x+12
5x+y=12
y- 12 = 5(x - 1)
5x+y=-1
Answer:
y= -5x+12
Step-by-step explanation:
slope int form ; y=mx+b
that is the only option in that form.
Answer:
the equation is y = 5x + 12
Step-by-step explanation:
The equation of line is 10x - 2y=-2
Write this equation in slope intercept form of line y = mx + b
[tex]10x-2y=-2\\\\2y=10x+2\\\\y=5x+1[/tex]
Therefore, the slope of the line is m = 5
Now, we know that parallel lines have same slope.
Hence, slope of the required line is also 5.
Thus, the equation of line is in the form y = 5x + b
Now, use the point (0,12) to find b
12= 5(0) + b
b = 12
Hence, the equation is y = 5x + 12
Simplify your answer.
Answer: 123.5 in^2
Step-by-step explanation: The formula for the area of a trapezoid is a+b/2 x h. In other words, base 1 plus base 2 divided by 2, and multiplied by the height. Plug in the numbers. The equation is:
6+7/2 x 19 = 123.5.
Since you are finding the area, the answer would be in inches squared. The answer is 123.5 in^2.
What are the coordinates of the vertices of the image of
rectangle WXYZ after the transformation Ro 90°(x, y)?
W'(-4,-1)
X'
Y'
Z'(-4, 2)
Answer:
W (-1, 4) ---> W' (-4, -1)
X (-1, 2) ---> X' (-2, -1)
Y (2, 2) ---> Y' (-2, 2)
Z (2, 4) ---> Z' (-4, 2)
Step-by-step explanation:
We are given the graph with a rectangular figure WXYZ and we are to find the coordinates of its vertices W'X'Y'Z' after the transformation of 90° rotation.
We know that, the rule for 90° rotation of a point (x, y) gives (-y, x).
So,
W (-1, 4) ---> W' (-4, -1)
X (-1, 2) ---> X' (-2, -1)
Y (2, 2) ---> Y' (-2, 2)
Z (2, 4) ---> Z' (-4, 2)
Answer
W'
✔(-4,1)
X'
✔ (-2, -1)
Y'
✔ (-2, 2)
✔Z'(–4, 2)
Step-by-step explanation:
the larger of two consecutive integers is 7 greater than twice the smaller. Find the integers. A. 4,5 B. -8, -9 C. -5, -6
Answer:
The integers are -5 , -6 ⇒ answer C
Step-by-step explanation:
* Lets explain the meaning of consecutive numbers
- Consecutive numbers are numbers that follow each other in order.
- They have a difference of 1 between every two numbers
- Consider that the smaller of two consecutive integer is n, then the
larger one will be n + 1
* In the problem
∵ The larger of the two consecutive integers is 7 greater than twice
the smaller
- That means the larger one is 7 plus twice the smaller
∵ The smaller one is n
∵ The larger one is n + 1
∴ n + 1 = 2(n) + 7
∴ n + 1 = 2n + 7
- Subtract n from both sides
∴ 1 = n + 7
- Subtract 7 from both sides
∴ -6 = n
∴ The smaller number is -6
∵ The greater number is n + 1
∴ The greater number = -6 + 1 = -5
* The integers are -6 , -5
