Answer:
<h3>
y = 2(x - 3)² - 20</h3>
Step-by-step explanation:
y = a(x - h)² + k - vertex form of the equation of the parabola with vertex (h, k)
So the equation of the parabola with vertex (3, -20):
y = a(x - 3)² + (-20)
y = a(x - 3)² - 20
The parabola passes through point (7, 12) so if x=7 then y=12
12 = a(7 - 3)² + (-20)
12 +20 = a(4)² - 20 +20
32 = 16a
a = 2
Therefore the equation of the parabola with vertex (3, -20) and that passes through point (7, 12):
y = 2(x - 3)² - 20
I think its 4.8 miles, dont hold me to that though
Answer:
m = 3; b = -12
Step-by-step explanation:
In order to answer the question definitively, we must assume you intend for the equation to be an identity.
6(2x -5) -(mx +2) = 9x +b
12x -10 -mx -2 = 9x +b
Equating x terms:
12x -mx = 9x
12 -m = 9 . . . . . . divide by x; next, add m-9
12 -9 = m = 3
Equating constant terms:
-10 -2 = b
-12 = b
