12x−5y−8
or 39x−52y+91= ± (60x−25y−40)
Taking the positive sign we get 21x+27y−131=0 as one bisector
Taking the negative sign we get 99x−77y+51=0 as the other bisector

The answer is #3
Step-by-step explanation:
The down payment is 5 so the chart will start at 5. It will then increase by 2.50 each time.
I think, it's the symbol of the inches.
3" = 3 inches
or it's the second derivative of the function

Question 2(Multiple Choice Worth 1 points)
(08.02 MC)
The function f(t) = 4t2 − 8t + 7 shows the height from the ground f(t), in meters, of a roller coaster car at different times t. Write f(t) in the vertex form a(x − h)2 + k, where a, h, and k are integers, and interpret the vertex of f(t).
f(t) = 4(t − 1)2 + 3; the minimum height of the roller coaster is 3 meters from the ground
f(t) = 4(t − 1)2 + 3; the minimum height of the roller coaster is 1 meter from the ground
f(t) = 4(t − 1)2 + 2; the minimum height of the roller coaster is 2 meters from the ground
f(t) = 4(t − 1)2 + 2; the minimum height of the roller coaster is 1 meter from the ground
