Answer:
-163.64..................
Answer:
All real values of x where x < −1.
Step-by-step explanation:
There is a turning point at x= 1 and f(x) = -4 and it open upwards.
So it decreases for all real values of x where x < 1. But it passes through the point (-1, 0) after which the values of the function become negative.
So the answer is all real values where x < -1.

Answer:
Please check the explanation.
Step-by-step explanation:
Given the equation
subtract 
from both sides
∵ 
Total seats: 52 x 7 + 8 x 12 = 364 + 96 = 460
Total cost for total seats = 460 x 23 = 10,580
Cost for buses: 150 x 7 + 80 x 8 = 1050 + 640 = 1690
Total cost = 10,580 + 1,690 = $12,270
Answer:
(C-D)/A = B
Step-by-step explanation:
C = AB + D
Subtract D from both side
C-D = AB + D-D
C-D = AB
Divide each side by A
(C-D)/A = AB/A
(C-D)/A = B
