All you need to do is multiply it so it will be 1,791
Axis -b/2a=-12/2*3=-2
vertex(-2,-3)
Answer:
7f
r = ----------- - 4
z
Step-by-step explanation:
I will assume that you meant:
7f
z = ------------
r + 4
Solve for r. Start by interchanging z and (r + 4):
7f
r + 4 = -----------
z
Now subtract 4 from both sides. This isolates r:
7f
r = ----------- - 4
z
A=7.51
B=3.49
C=1.371
D0.1371
