-5x⁽²⁺³ˣ) - 2x(x-4)
Let's seperate the equation, and do the first half first.
-5x ⁽²⁺³ˣ⁾
Multiply -5x with 2.
Then, multiply 3x with -5x.
That gives us: -10x - 15x²
Now, let's do the second half.
2x(x-4)
2x²-8x
Now, let's put them together.
(-10x-15x²) - (2x²-8x)
Add like terms.
(-2x² - 15x²) - (-8x - 10x)
Simplify.
-17x² - (-18x)
-17x² + 18x

Step-by-step explanation:
Answer with explanation:
Pre-image =Rectangle EFGH
Image = Rectangle E'F'G'H'
Stretch Factor = 2.5
Coordinates of Point H= (-2,0)
If Coordinate of any point is (x,y) and it is stretched by a factor of k , then coordinate of that point after stretching = (k x , k y).
So, Coordinates of Point H' will be=(-2×2.5,0×2.5)
= (-5,0)
Answer:
B and E
Step-by-step explanation:
The slope is the one with the x next to it, and it's reasonable to say that when it asks for a "negative slope", the slope has to be negative. In that case B and E have negative slopes so they both have to be correct.
Answer a:
Figure 4 = 5 blocks up, 5 blocks right
Figure 5 = 6 blocks up, 5 blocks right
Answer b: Grows 2 blocks each time, 1 blocks at the top and 1 blocks on the right.
Answer c: Since you add 2 blocks each time, you do the opposite so you subtract 2 blocks. The answer will be 1 block.
