Which point is not on the graph of the function y = x + 5?
(2, 7)
(6, 11)
(220, 225)
(10, 5)
Answers
Answer:
(10, 5 )
Step-by-step explanation:
To determine which points lie on the graph or not.
Substitute the x- coordinate of the point into the equation and if the value agrees with the y- coordinate of the point then the point is on the graph.
(2, 7 )
y = 2 + 5 = 7 ← True thus point is on the graph
(6, 11 )
y = 6 + 5 = 11 ← True thus point is on the graph
(220, 225 )
y = 220 + 5 = 225 ← True thus point is on the graph
(10, 5 )
y = 10 + 5 = 15 ≠ 5 ← Point is not on the graph

Answers
Answer:
m∠QRT = 90°
m∠QRT = m∠SRT
Step-by-step explanation:
Triangle QST is isosceles with QT ≅ ST. In isoscels triangle QST, angles STR and RTQ are congruent.
RT is angle T bisector, so angles QTR and STR are congruent.
Consider two triangles QTR and STR. In these triangles:
TR ≅ TR (reflexive property); ∠QTR ≅ ∠STR (given);QT ≅ ST (given).By SAS postulate, these two triangles are congruent. Two congruent triangles have congruent corresponding sides, so
QR ≅ SR ∠QRT ≅ ∠SRTAngles QRT and SRT are supplementary (add up to 180°). Since these two angles are congruent, they have the same measure equal to [tex]\frac{1}{2}\cdot 180^{\circ}=90^{\circ}[/tex]
So, true options are
m∠QRT = 90°
m∠QRT = m∠SRT
Answer:
The correct options are;
m[tex]\angle[/tex]QRT [tex]=90^o[/tex]
m[tex]\angle[/tex]QRT [tex]=[/tex] m[tex]\angle[/tex]SRT
Step-by-step explanation:
Given information;
The triangle QST is isosceles with QT ≅ ST.
The angle STR ans RTQ are congruent.
Now, consider two triangles QTR and STR
In the following triangle
1. TR ≅ TR (having reflective property)
2. [tex]\angle[/tex]QTR ≅ [tex]\angle[/tex]STR (as given in question)
3. QT ≅ ST (as given in information)
Now, according to SAS postulate , two congruent triangle have congruent corresponding to their sides ,
Hence ,
1. QR ≅ SR
2. [tex]\angle[/tex]QRT ≅ [tex]\angle[/tex]SRT
Since, this above two angles are congruent they will have same measure
That will be
[tex]=(180/2)\\=90 ^o[/tex]
Hence, The correct options are;
m[tex]\angle[/tex]QRT [tex]=90^o[/tex]
m[tex]\angle[/tex]QRT [tex]=[/tex] m[tex]\angle[/tex]SRT

Which is greater, 9 x 10-2 or 3 x 10-4? How many times
greater is the number you chose than the other number?
Explain your reasoning.
Answers
Final answer:
[tex]9 \times 10^{-2 }(0.09)[/tex] is greater than [tex]3 \times 10^{-4} (0.0003)[/tex], and is 300 times greater.
Explanation:
To determine which is greater between [tex]9 \times 10^{-2 }[/tex] and [tex]3 \times 10^{-4}[/tex]we need to understand how to interpret numbers in scientific notation. The expression [tex]9 \times 10^{-2 }[/tex] means 9 times 1 following 2 zeroes to the left, resulting in 0.09. In the case of [tex]3\times 10^{-4}.[/tex] it means 3 times 1 following 4 zeroes to the left, producing 0.0003.
Comparing these values, [tex]9 \times 10^{-2 }[/tex] is clearly the larger number because 0.09 is greater than 0.0003. To find out how many times greater it is, we divide the larger number by the smaller one: 0.09 / 0.0003 equals 300. Therefore, [tex]9 \times 10^{-2 }[/tex]is 300 times greater than [tex]3\times 10^{-4}.[/tex]

The hypotenuse of a right triangle is 13 inches. If the long leg is 7 inches longer than the short leg, find the lengths of the leg using the Pythagorean theorem
Answers
Answer:
The length of the short leg is 5 inches and the leg of the long leg is 12 inches
Step-by-step explanation:
Let
a -----> the long leg of a right triangle
b ----> the short leg of a right triangle
c ----> the hypotenuse of a right triangle
we know that
Applying the Pythagoras Theorem
[tex]c^{2} =a^{2}+b^{2}[/tex] -----> equation A
we have that
[tex]a=b+7[/tex] -----> equation B
[tex]c=13\ in[/tex] ----> equation C
Substitute equation B and equation C in equation A and solve for b
[tex]13^{2} =(b+7)^{2}+b^{2}[/tex]
[tex]169=b^2+14b+49+b^2[/tex]
[tex]2b^2+14b+49-169=0[/tex]
[tex]2b^2+14b-120=0[/tex]
Solve the quadratic equation by graphing
The solution is [tex]b=5\ in[/tex]
see the attached figure
Find the value of a
[tex]a=b+7[/tex] ----> [tex]a=5+7=12\ in[/tex]
therefore
The length of the short leg is 5 inches and the leg of the long leg is 12 inches
The lengths of the leg : 12 and 5
Further explanationQuadratic function is a function that has the term x²
The quadratic function forms a parabolic curve
The general formula is
[tex]\large {\boxed {\bold {f (x) = ax ^ 2 + bx + c}}}[/tex]
where a, b, and c are real numbers and a ≠ 0.
There are 3 ways to solve quadratic equations
a. factoring b. perfect squared c. quadratic formula
We use the factoring method
Quadratic equation x² + bx + c = 0 is equivalent to quadratic equation
[tex]{\displaystyle {x ^ 2 + (p + q) \times \: pq}}[/tex]
where p + q = b and px q = c
for a = 1, the result of factoring is (x + p) (x + q)
If at an angle there is an angle of 90 degrees, this triangle is said to be a right angle
There is a hypotenuse in this triangle which is the sum of the two sides
c² = a² + b²where c = hypotenuse
This formula is known as the Pythagorean theorem which states that:
the hypotenuse or the longest side in a right triangle equal to the sum of the squares of the other sides.
The hypotenuse of a right triangle is 13 inches
then c = 13
If the long leg is 7 inches longer than the short legthen a = b + 7
Then the phytagorean equation becomes:
(b + 7)² + b² = 13²
49+14b+b²+b²=169
49+14b+2b²=169
2b²+14b-120=0
b²+7b-60=0
factoring
(b-5)(b+12)=0
b=5 or b=-12
we use positive number ⇒5
So :
the long leg = b+7=5+7=12
the short leg = b = 5

Answer:x f(x) = 2.5x − 10.5 g(x) = 64(0.5x)
2 f(2) = 2.5(2) - 10.5 g(2) = 64(0.5*2)
f(2) = 5 - 10.5 g(2) = 64(1)
f(2) = -5.5 g(2) = 64
3 f(3) = 2.5(3) - 10.5 g(3) = 64(0.5*3)
f(3) = 7.5 - 10.5 g(3) = 64(1.5)
f(3) = -3 g(3) = 96
4 f(4) = 2.5(4) - 10.5 g(4) = 64(0.5*4)
f(4) = 10 - 10.5 g(4) = 64(2)
f(4) = -0.5 g(4) = 128
5 f(5) = 2.5(5) - 10.5 g(5) = 64(0.5*5)
f(5) = 12.5 - 10.5 g(5) = 64(2.5)
f(5) = 2 g(5) = 160

Suppose that the length of a rectangle is 4 times the width. If the area is 900 square feet, then what is the width of the rectangle, in feet?
Answers
Answer:
Width 15 feet
Step-by-step explanation:
Use formula
[tex]A_{rectangle}=\text{Width}\cdot \text{Length}[/tex]
Let x feet be the width of the rectangle.
If the length of a rectangle is 4 times the width of the rectangle, then the length is 4x feet.
The area of the rectangle is 900 square feet, so
[tex]900=x\cdot 4x\\ \\900=4x^2\\ \\x^2=225\ [\text{Divided by 4}]\\ \\x=\pm 15[/tex]
The width cannot be negative, then x=15 feet and 4x=60 feet.
Final answer:
To find the width of the rectangle when the length is 4 times the width and the area is 900 square feet.
Explanation:
To find the width of the rectangle:
Let the width be w feet.
Since the length is 4 times the width, the length is 4w feet.
Given that the area is 900 square feet, we can set up the equation w * 4w = 900 to solve for w.
4w² = 900
w² = 225
w = 15 feet
Therefore, the width of the rectangle is 15 feet.

What square roots of 10 lies between which two whole numbers?
Answers
The square root of 10 lies between two whole numbers, 3 and 4. This concept can be understood using number sense and geometry.
The square root of 10 falls between two whole numbers. To determine these two numbers, we need to consider the closest perfect square numbers to 10. These are 9 (the square root of 9 is 3) and 16 (the square root of 16 is 4). Hence, the square root of 10 must be somewhere between 3 and 4. Using a calculator, we find the approximate square root of 10 to be around 3.16. So, the square root of 10 lies between 3 and 4.
This kind of problem is related to number sense and geometry, especially when it comes to understanding square roots.

7 3/4% as a fraction in simplest form
Answers
this probably isn't right but this is what the internet says 31/400
To convert 7 3/4% to a fraction in simplest form, add the whole number and the fractional part together, find a common denominator, and simplify if necessary.
Explanation:To convert 7 3/4% to a fraction in simplest form, we first need to convert the mixed number to an improper fraction. The whole number part, 7, can be written as 7/1. Adding the fractional part, we have (7/1) + (3/4). To add fractions, we need a common denominator, which in this case is 4. So, we rewrite the fractions as (28/4) + (3/4). Adding the numerators, we get 31/4. Since we want the fraction in simplest form, we can simplify 31/4 by dividing both the numerator and the denominator by their greatest common factor, which is 1. Therefore, 7 3/4% as a fraction in simplest form is 31/4.

How are absolute values used to describe quantities ?
Answers
Answer:
Absolute value is a number's distance from 0, so when comparing quantities, such as positive and negative, the greater absolute value is of that number.
For ex:
|-11| > |6| , because |-11| = 11, |6| = 6, and 11 > 6.
So, |-11| > |6|
Absolute values are used to describe the distance of any values from the point 0. Hence, absolute values are used to express the positive value a quantity.
Quantities may be positive or negative depending on their relative position from Zero.
Positive values are to the right of Zero; While negative values are to the left of Zero.
Since quantities maintain equal distance either to the left or right of Zero; Absolute values are only concerned with the magnitude of a quantity from Zero and not the direction.
