What type of transformation happened from (x,y) --> (-x,y)?
-----
A.Rotation 90*
B.Reflection over the y-axis
C.Translation left 1
D.Reflection over the x-axis
Answer:
B
Step-by-step explanation:
This is a reflection over the y-axis. The x value is changing sign while the y value is staying the same. The general rule for a reflection over the y axis is (x,y) --> (-x,y), and similarly for a reflection over the x axis is (x,y) --> (x,-y). When you reflect a point over an axis, you flip the sign of the opposite value.

Please help!! It has to be *TWO* angles
{An angle measures 150° less than the measure of its supplementary angle. What is the measure of each angle?}
Answer:
165° & 15°
Step-by-step explanation:
Let the first angle be 'a'
second angle be (a-150°)
a+(a-150°) = 180°
2a=180°+150°
2a=330°
a=330/2
a=165°
first angle is 165°
second angle is 165-150=15°

how do you express 11/20 as a percent
Answer:
The answer is 55%
1. 11÷20= 0.55
Now that the number is a decimal, we multiply 0.55 and 100 to get our result.
0.55 x 100 = 55%
∠M and ∠Nare supplementary. If m∠N= 33°, what is ∠M?
Answer:
∠M will be 147°
Step-by-step explanation:
Supplementary means adding up to 180° so take your 180° to subtract 33° from it and you'll have your answer.
Answer:
147
Explanation:
Supplementary angles all equal to 180, so that means that <M and <N must be both equal to 180.
If you want to find <M, you have to do 180 - 33, which equals to 147.
know the answer for this???
x = 5 makes 2x≤ 10 true but not 2x < 10 because "≤" means less than or equal to, which means 2x would be the same as 10, so 10 ÷ 2 = 5, x = 5.
Answer:
Step-by-step explanation:
2x ≤ 10, when x = 5
2(5) ≤ 10
10 ≤ 10 (10 is less than OR equal to 10)
2x < 10, when x = 5
2(5) < 10
10 < 10 (10 is less than 10) - that is false
x = 5 does not makes 2x < 10 true because 10 can't be less than 10.
Hope this helps!

3. Which two integers are 7 units away from the number 5 on a number line?
A. -2 and 2
B. -2 and 7
C. -7 and 7
D. -2 and 12
Answer:
2B
3D
Step-by-step explanation:
2A is
a/b + -a/-b = a/b + a/b = 2a/b
this is NOT 0/0. you can't add numerator and denominator. when you have the same denominator, you can only add the numerator.
and don't forget : -×- and -/- are both + !
2B
you do not multiply anything. you ADD (but again NOT the denominators) !
and +×- or +/- = - !
overall this this adding a negative number to the same positive number. the result : always 0
2C
cannot be added like that. first you would have to bring both to a common denominator. but then you ADD !
2D
very similar to 2C.
3
5 + 7 = 12
5 - 6 = -2
these are the 2 integers 7 units away from 5.

Let p = number of pounds of candy Lena will buy
Given:
Candy = $5 per poundLena will spend less than $40Create an inequality using the given information:
⇒ 5p < 40
Solve the inequality:
⇒ 5p < 40
Divide both sides by 5
⇒ p < 8
Molly is painting a model house and needs to know how much paint she will need. She knows the surface area of the prism is 216 square inches and the surface area of the pyramid is 84 square inches.
1. Which surface is shared by the two solids? What are the dimensions of this surface?
2. There is another surface that Molly does not need to paint, because it won’t show when she displays the model house. Describe that surface, and explain why it doesn't need to be painted.
3. To find the area Molly needs to paint, she should add the surface areas of both solids and subtract:
twice the area of the triangle
twice the area of the square
three times the area of the square
the area of the square
4. Find the area Molly needs to paint. Show your work, and be sure to include units with your answer.
Oh and here's an image to help you out
Answer:
1. a square which is 6 × 6in
2. the inside of the prism or cube as it is not seen from the outside
3. the area of the square - 6 × 6 = 36in
4. 6 x 6 = 36 / one face of prism
× 5 = 180
4 × 6/2 = 12 / one face of pyramid
x 5 = 60
60 + 180 = 240
