Step-by-step explanation:
solve the equation -12=q-17
Answer:
q = 5
Step-by-step explanation:
Given
- 12 = q - 17 ( add 17 to both sides )
5 = q ⇒ q = 5
Answer:
q=5
Step-by-step explanation:
The equation is -12=q-17
In this equation we have to find the value of q.
So move the constant to the L.H.S
-17 will become +17 when it moves to the L.H.S
17-12=q
5=q
Thus the value of q is 5....
Matrices X and Y both measure 2x2 and are inverses of each other. Which matrix represents their product?
Answer:
When a matrix is multiplied by its inverse the result will be the identity matrix. If we multiply two matrix with the same size, the resulting matrix will have the same dimension.
Therefore, if we multiply the matrices X and Y we will get a 2x2 identity matrix, as follows:
[tex]\left[\begin{array}{ccc}1&0\\0&1\\\end{array}\right][/tex]
Answer:
[tex]\left[\begin{array}{ccc}1&0\\0&1\end{array}\right][/tex]
Step-by-step explanation:
We are asked find the matrix that represent the product of matrices X and Y both measures [tex]2\times 2[/tex] and inverse of each other.
For a matrix multiplication to be defined, the number of columns in the first matrix must be equal to number of rows in the second matrix.
Since the both matrices are [tex]2\times 2[/tex] (same number of column and row), then the product of both matrices would result in [tex]2\times 2[/tex] matrices.
We also know that the multiplication of a matrix with its inverse results in identity matrix.
Therefore, our matrix would be a [tex]2\times 2[/tex] identity matrix as:
[tex]\left[\begin{array}{ccc}1&0\\0&1\end{array}\right][/tex].

Carmen y Carlos hacen pizzas para vender. La materia prima necesaria para hacer una pizza grande les cuesta $5.00 y para una pizza pequeña $3.00. Si disponen de $570.00 y quieren hacer 150 pizzas, ¿cuántas pizzas de cada tamaño podrán hacer?
Answer:
A large pizza costs $5 and a small pizza costs $3.
Let 'x' be the number of large pizzas and 'y' the number of small pizzas. We have that:
x + y = 150
5x + 3y = 570
Solving the system of equations:
x + y = 150 → 3x + 3y = 450 → 3y = 450 - 3x
5x + 3y = 570 → 5x + 450 - 3x = 570
2x = 120
x = 60
y = 150 - 60 = 90
Therefore. Carmen y Carlos will make 60 large pizzas and 90 small pizzas.

Answer:
Option 1 is correct. i.e 2 hours walking; 12 hours running
Step-by-step explanation:
We are given the equations
3w + 6r ≥ 36
3w + 6r ≤ 90
We will check which of the option satisfy the above equations.
1) 2 hours walking; 12 hours running
w = 2 and r =12
3w + 6r ≥ 36
3(2) + 6(12) ≥ 36
6+72 ≥ 36
78 ≥ 36
3w + 6r ≤ 90
3(2) + 6(12) ≤ 90
6+72 ≤ 90
78 ≤ 90
Both equations are satisfied. Option 1 is correct.
2) 4 hours walking; 3 hours running
w = 4 and r =3
3w + 6r ≥ 36
3(4) + 6(3) ≥ 36
12+18 ≥ 36
30 ≥ 36 (this equation doesn't hold as 30 < 36 and not < or equal to 36)
3w + 6r ≤ 90
3(4) + 6(3) ≤ 90
12+18 ≤ 90
30 ≤ 90
So, Option 2 is incorrect.
3) 9 hours running 12 hours walking
w = 9 and r =12
3w + 6r ≥ 36
3(9) + 6(12) ≥ 36

99 ≥ 36
3w + 6r ≤ 90
3(9) + 6(12) ≤ 90
27+72 ≤ 90
99 ≤ 90 (this equation doesn't hold because 99 is greater than 90 and not less than 90)
Option 3 is incorrect.
4) 12 hours walking; 10 hours running
w = 12 and r =120
3w + 6r ≥ 36
3(12) + 6(10) ≥ 36
36+60 ≥ 36
96 ≥ 36
3w + 6r ≤ 90
3(12) + 6(10) ≤ 90
36+60 ≤ 90
99 ≤ 90 (this equation doesn't hold because 96 is greater than 90 and not less than 90)
Option 4 is incorrect.

If sin0=-1/2 and 0 is in quadrant III then tan0=
Answer:
tan O = √3/ 3.
Step-by-step explanation:
The tangent is positive in quadrant 3.
The adjacent side has length √((2^2 - (-1)^2)
= -√3.
So tan O = -1 / -√3
= 1 / √3
= √3/ 3.
To determine tan(θ) for an angle θ where sin(θ) = -1/2 and θ is in quadrant III, we perform the following steps:
1. **Understand the given information:** When sin(θ) = -1/2, it means the opposite side to angle θ in a right triangle is -1 and the hypotenuse is 2. Since θ lies in the third quadrant, both sine and cosine values are negative, implying that the adjacent side length must also be negative.
2. **Use the Pythagorean theorem:** For a right triangle:
\[ \text{hypotenuse}^2 = \text{opposite}^2 + \text{adjacent}^2 \]
Substituting hypotenuse and opposite side values:
\[ 2^2 = (-1)^2 + \text{adjacent}^2 \]
Simplify and solve for the adjacent side:
\[ 4 = 1 + \text{adjacent}^2 \]
\[ 3 = \text{adjacent}^2 \]
\[ \text{adjacent} = \sqrt{3} \] or \[ \text{adjacent} = -\sqrt{3} \]
Since the angle is in the third quadrant where cosine is also negative, we must take the negative square root:
\[ \text{adjacent} = -\sqrt{3} \]
3. **Calculate tan(θ):** By definition,
\[ \tan(θ) = \frac{\text{opposite}}{\text{adjacent}} \]
Substitute the known side lengths:
\[ \tan(θ) = \frac{-1}{-\sqrt{3}} \]
4. **Simplify the expression:**
\[ \tan(θ) = \frac{1}{\sqrt{3}} \]
To rationalize the denominator:
\[ \tan(θ) = \frac{1}{\sqrt{3}} \times \frac{\sqrt{3}}{\sqrt{3}} \]
\[ \tan(θ) = \frac{\sqrt{3}}{3} \]
Thus, if sin(θ) = -1/2 and θ is in quadrant III, then tan(θ) = √3/3. Note that in the context of trigonometry, it is often assumed that the angle and the ratios are dimensionless, so a negative 'opposite' simply reflects the direction along the coordinate axis rather than a literal negative length.

13. For what value of b would the following system of equations have an infinite number of solutions? 9x + 12y = 21
6x + 8y = 7b Please explain and show steps :)
Answer:
b=2
Step-by-step explanation:
9x + 12y = 21
6x + 8y = 7b
To have an infinite number of solutions, the two equations must be equal
Take the first equation and divide by 3, since it is a factor of all the terms
9x/3 + 12y/3 = 21/3
3x+4y = 7
Then multiply by 2 to get the x term equal
2*3x + 2*4y = 2*7
6x +8y = 7*2
Comparing this to the second equation
6x + 8y = 7b
b must equal 2

What is the value of the expression when y = 2?
a)14
B)0
c)7

Answer:
The correct option is A
Step-by-step explanation:
The expression is
2y3 - 27 + 5y2 + (25 / 5)
Substitute the value of y=2 in the expression:
=2(2)³-27+5(2)²+(25/5)
We know that 2³ means multiply 2 three times
2³= 2*2*2=8
Likewise 2²=2*2=4
=2(8)-27+5(4)+(25/5)
=16-27+20+25/5

TZ = 2*(S + P) Divide by 2
TZ/2 = 2(S + P)/2 Do the division
TZ/2 = S + P Subtract P from both sides
TZ/2 - P = S That's one answer. You could refine it.

The system of equations y=2x-1 and y=-1/4x+3 is shown on the graph below. What is a reasonable estimate for the solution?
Answer:
Something close to (1.8,2.6)
Step-by-step explanation:
y=2x-1
y=-1/4 x+3
Since y=2x-1 and y=-1/4 x +3 then 2x-1=-1/4 x +3.
I'm going to multiply both sides by 4 to get rid of the fraction:
8x-4=-x+12
Add x on both sides:
9x-4=12
Add 4 on both sides:
9x=16
Divide both sides by 9:
x=16/9 is approximately 1.8 when put into calculator.
Now if x=16/9 and y=2x-1, then y=2(16/9)-1=32/9-1=32/9-9/9=(32-9)/9=23/9.
y=23/9 is approximately 2.6 when put into calculator.
So we are looking for an ordered pair pretty close to (1.8,2.6).
The graph is shown to you so I will put one here as well:

Madeline is standing 2x- 4 feet from the base of a tree. The height of the tree is 5x + 6 feet. Find the equation that shows
the straight-line distance from Madeline's feet to the top of the tree in terms of x.
Provide your answer below:
Answer:
c = sqrt( 29x^2 + 44x + 52)
Step-by-step explanation:
This is an application of the Pythagorean theorem
c = sqrt(a^2 + b^2)
a = 2x - 4
b = 5x + 6
c = sqrt( (2x - 4)^2 + (5x + 6)^2 ) Substitute and expand
c = sqrt( 4x^2 - 16x + 16 + 25x^2 + 60x + 36) Collect like terms
c = sqrt( 4x^2 + 25x^2 - 16x + 60x + 16+36) Combine the like term pairs.
c = sqrt( 29x^2 + 44x + 52)
This does not factor into anything very nice.
Answer:
Madeline is standing 2x - 4 feet from the base of a tree, and the height of the tree is 5x + 6
Now we want to know the distance from Madeline's feet to the top of the tree.
You could picture it as a triangle rectangle, where the cathetus is the distance between Madeline and the tree and the distance between the floor and the top of the tree, in this case the distance between Madeline's feet and the top of the tree is the hypotenuse of such triangle rectangle, and can be obtained using the Pythagorean theorem: "the square of the hypotenuse is equal to the sum of the square cathetus"
then:
[tex]H^2 = (2x - 4)^2 + (5x + 6)^2[/tex]
[tex]H^2 = (4x^2 -16x + 16) + (25x^2 + 60x +36)[/tex]
[tex]H^2 = (29x^2 + 44x + 52)[/tex]
[tex]H = \sqrt{ (29x^2 + 44x + 52)}[/tex]
this is the distance from Madeline's feet to the top of the tree in terms of x.

Write an equation: After withdrawing $7 from a checking account, Carla’s balance was $89
The equation for the situation where Carla withdraws $7 and is left with an $89 balance is: B - $7 = $89. So Carla's initial balance was $96.
When writing an equation based on the statement that after withdrawing $7 from a checking account, Carla’s balance was $89, we are essentially working out what Carla's balance was before she made the withdrawal.
If we let the variable B represent Carla's initial balance, then after she withdraws $7, her new balance is B - $7.
Since it's given that her balance after the withdrawal is $89, we can write the following equation to represent the situation:
B - $7 = $89
To find the value of B, we would add $7 to both sides of the equation, which would give us:
B = $89 + $7
B = $96
So, Carla's initial balance before the withdrawal was $96.
What type of triangle can an isosceles triangle be? Secalene acute obtuse isosceles
An isosceles triangle is the following options, acute and isosceles, which is B and D. Remember that an isosceles triangle has 2 sides that are the same, so its D and every isosceles triangles are acute, not obtuse, so its B.
Hope this helped!
Nate
Answer:
Acute triangle
Step-by-step explanation:
A isosceles triangle is a triangle that has two equal sides.
It would not be a scalene triangle because in scalene triangles all the sides have different lengths.
It might be an acute triangles because all the angles in an acute triangle would be acute angles.
it wouldn't be an obtuse triangle because in an obtuse triangle there is at least one obtuse angle and the other 2 angles would be either acute, right, or obtuse.
It could be an isosceles triangle but that wouldn't make sense since its already an isosceles triangle.

PLEASE ANSWER QUICK!!! Identify the equation of the circle that has its center at (-8, 15) and passes through the origin.
The equation of the circle is [tex](x+8)^{2} +(y -15)^{2} = 289[/tex].
What is the general equation for the circle?The general equation of the circle is [tex](x-h)^{2} +(y-k)^{2} = r^{2}[/tex].
Where, (h, k) is the center and r is the radius of the circle.
Let the equation of the circle be
[tex](x-h)^{2} +(y-k)^{2} =r^{2}..(i)[/tex]
According to the given question.
The center of the circle is (-8, 15).
⇒ (h, k) = (-8, 15)
And, the circle is passing through origin i.e. (0, 0).
Since, the center of the circle is (-8, 15).
So, the equation (i) can be written as
[tex](x-(-8))^{2} +(y - 15)^{2} = r^{2}[/tex]
Also, the circle is passing through (0, 0).
Therefore,
[tex](0+8)^{2} +(0-15)^{2} = r^{2}[/tex]
[tex]\implies 64+ 225 = r^{2} \\\implies 289 = r^{2} \\\implies r=\sqrt{289} \\\implies r = 17[/tex]
So, the radius of the circle is 17 unit and its center is (-8, 15).
Therefore, the equation of the circle is
[tex](x+8)^{2} +(y-15)^{2} = 289[/tex]
Hence, the equation of the circle is [tex](x+8)^{2} +(y -15)^{2} = 289[/tex].
