Answer:
y - 12 = 9(x - 4)
Step-by-step explanation:
The vertex (h, k) is (4, 12) and the point (5, 21) is on the graph. Assuming that this is a vertical parabola, opening up (because the coordinate 21 is greater than the coordinate 12), we insert the knowns into y - k = a(x - h)^2, obtaining
21 - 12 = a(5 - 4), or 9 = a. With a known, we can write the desired equation:
y - 12 = 9(x - 4)
Answer:
10x−31
Step-by-step explanation:
Let's simplify step-by-step.
10x+9−40
=10x+9+−40
Combine Like Terms:
=10x+9+−40
=(10x)+(9+−40)
=10x−31
Hope this helps and can you please give me brainliest ;-)
