Step-by-step explanation:
And what is "aeb"
7/4
4 goes into 7 one time.
3 left over.
1 3/4
Step-by-step explanation:
Remember that angles in the same segment are equal.
In here, AD is the segment, which means that angle ACD = angle ABD = 28°.
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.
