Answer:
2x^3−7x^2+16x−15
Step-by-step explanation:
(2x−3)(x^2−2x+5)
=(2x+−3)(x^2+−2x+5)
=(2x)(x^2)+(2x)(−2x)+(2x)(5)+(−3)(x^2)+(−3)(−2x)+(−3)(5)
=2x^3−4x^2+10x−3x^2+6x−15
=2x3−7x2+16x−15
Answer:
4.5
Step-by-step explanation:
when the height is 0 the ball will hit the ground
so the equation is
-12t²+54t=0
12t²-54t=0
2t²-9t=0
t(2t-9)=0
t=0
t=4.5
so the answer is
4.5
Answer:
H'(15, - 7)
Step-by-step explanation:
Given the translation < 10, - 11 >
Add 10 units to the x- coordinate of H and subtract 11 units from the y- coordinate of H, that is
H(5, 4) → H'(5 + 10, 4 - 11) → H'(15, - 7)

Answer:
- reflected across the x-axis
- vertically stretched by a factor of 2
- translated down 7 units
Step-by-step explanation:
When the function y = x³ is transformed to y = -2x -7, there are three transformations involved. The multiplication by 2 causes a vertical stretch by a factor of 2. The leading minus sign causes the function to be reflected over the x-axis, and the addition of -7 causes the graph to be translated down 7 units.
