To reflect in the line y = -x + 6, we translate everything down 6 first.
This will make it seem like we are reflecting in the line y = -x
(x,y) → (x, y-6)
Then, to reflect in the line y = -x, we switch the x- and y-coordinates and then make them negative
(x,y) → (-(y-6), -x)
Then we move everything back up again
(x,y) → (-(y-6), -x + 6)
I will present to you an example. Reflect the point (-4, 8) in the line y = -x + 6.
(-4,8) → (-(8-6), -(-4) + 6) → (-2, 10)
You should graph this out to confirm with the reflection line.
No because...
3(d+12) =8
Distribute the 3.
3d+36=8
Subtract the 36.
3d = -28
Divide by 3 to isolate d.
d = -28/3 or 9.33
we know that
Average Rate of Change. is the change in the y-value divided by the change in the x-value for two distinct points on the graph
So
in this problem
substitute the values in the formula above
Divide by 
both numerator and denominator
therefore
the answer is
Answer:
just graph 5 like usual.....
Step-by-step explanation:
The surface area of a cube is the combined area of all of its faces. The faces of a cube are squares, so to find the area of one face, we simply need to multiply the side length, which is 20, by itself.
20 * 20 = 400
So one face has an area of 400 units squared. To find the surface area, we just need to add all of the individual areas together. Cubes have 6 faces, so we can just multiply 400 by the amount of faces there are.
400 * 6 = 2400
The net, when folded into a cube, has a surface area of 2,400 units squared.
Hope that helped! =)
