2(-12) isn't 24.
It is -24.
So the answer would be 6.
The width is 2 and the length is 4 hope this helps!
Answer:
first you need to divide each side by -2
Step-by-step explanation:
start with dividing by -2, then you are left with -7 = m which is the answer.
We are given D (7, -3) and D'(2, 5).
SAppy the transformation
D'(x,y) → D(x-5, y+8).
Then
x=7 → x=7-5 = 2
y=-3 → y=-3+8 = 5
Answer: D (x-5, y+8) → D'
Here's our equation.

We want to find out when it returns to ground level (h = 0)
To find this out, we can plug in 0 and solve for t.


So the ball will return to the ground at the positive value of

seconds.
What about the vertex? Simple! Since all parabolas are symmetrical, we can just take the average between our two answers from above to find t at the vertex and then plug it in to find h!
