Answer:
the answer for X is -6
Step-by-step explanation:
g(X)=5/2x -1 and g(X)= - 1
sub -16 on g(X)
-16=5/2x -1
-16+1 = 5/2x
-15 = 5/2x
divide both sides by 5/2
X= -6
Y = m x + b , where m is the slope. The slope is the rise over the run or the change in x ( rooms cleaned ) over the change in y ( cost ).
125 = m * 1 + b
175 = m * 2 + b
-----------------------
b = 125 - m
175 = 2 m + 125 - m
m = 175 - 125
m = 50 ( the rate of change ), b = 75
The formula is: y = 50 x + 75
It means that the starting cost will be $75 and that for every room cleaned, the cost will rise for $50.
Answer:
1 1/8
Step-by-step explanation:
First, Make the first fraction into a new one with an equal denominator. (3/4 x2= 6/8)
Then, subtract the whole numbers (2-1=1) and the fractions (6/8-5/8= 1/8)
Lastly, add your two differences together and you get 1 1/8.
