X would be -2 to the second power
-2*-2^2 would give you 8 and 8-8 gives you 0
Answer:
21
Step-by-step explanation:
y = a(x-h)² + k
h = -6
k = - 7/2
h*k = (-6)*(-7/2) = 21
The answer would be to divide 1030 by 50 and you would get 21 coaches not 20 because 50x20=1000 and there are 30 remainder. Therefor, you would need that extra coach with some seats left to spare. so your answer is 21 coaches
