Answer:
(0, 5)
Step-by-step explanation:
F(x)=3x-2
f(-6)=3(-6)-2
=-18-2
=-20
6x - 15 = 90
6x = 90 + 15
6x = 105
x = 105/6
x = 17.5
The answer is D. All you have to do is graph the equation, and you will have the vertex and the roots. By the way, you can rule out B and C because those two do not follow the rules of a quadratic. Also, A and B have the wrong axis of symmetry, because the rocket lands after 10 seconds.
W + 54 = s
w + 54 = 72
Answer: C
