it is the same denominator therefore only the numerators are added and the sign is maintained. The answer is -12/9 but it can be reduced to -4/3.
Y = mx + b
m = (y2 - y1)/(x2 - x1)
y = (26,600 - 18100)/(20 - 10)x + b
y = 850x + b
18100 = 850(10) + b
b = 9600
R(x) = 850x + 9600
Answer:
6
Step-by-step explanation:
C - 11 /9 = 9
Multiply both sides by 9
c - 11 = 81
add 11 to each side to isolate c
c = 81 + 11 = 92
The answer is 22K/cubic ft
