Answer:
that would also be car 1, because in a rotation like that its like you do a spin and come back to the same position, that is a 360 rotation.
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: y=3x+3 would be your answer

Answer:
1120°
Step-by-step explanation:
Use the sum of interior angles formula:
Where n is the number of sides.
In a nonagon, there are 9 sides, substitute 9 for n:
Since our nonagon is a regular nonagon, all 9 angles measure the same, so each angle measures:
Subtract 140 from 1260:
