Answer:
Step-by-step explanation:
<u>The equation to reflect the monthly plans:</u>
- Plan A f(x) = 0.16x + 12
- Plan B g(x) = 0.12x + 29
<u>We need to find the value of x when f(x) = g(x):</u>
- 0.16x + 12 = 0.12x + 29
- 0.16x - 0.12x = 29 - 12
- 0.04x = 17
- x = 17/0.04
- x = 425 minutes
<u>The cost is:</u>

Vertex is directly in middle of directix and focus
distance from 8 to -8 is 16
16/2=8
so 8 below focus (since 8>-8) is the point (0,0
vertex is (0,0)
nice
it opens up because focus is above directix
also it goes up down so
4p(y-k)=(x-h)^2
(h,k) is veretx
we got that (h,k) is (0,0)
and p is distance from vertex to focus which is 8
so
4(8)(y-0)=(x-0)^2
32y=x^2
y=(1/32)x^2
Since it’s vertical it would be x=-7
