Answer:
d = v/53
Step-by-step explanation:
Divide both sides by 53 to make d the subject of the formula
That number would be less than seventeen

To find the minimum, take the derivative of the function and equate to zero:
f(x) = y = x² + ax + b
dy/dx = 2x + a = 0
Substitute x =6:
a = -2x
a = -2(6)
a = -12
Then, substitute x = 6, y = 7 and a = -12 to find b.
7 = (6)² -12(6) + b
7 + 36 = b
b = 43
Thus, a = -12 and b = 43
The answer to 38-45 is equal to -7
