I think it proved by the arc intercepting kl making it an interior alternate angle which means it equal to each other
10 x=16
100 160
160+0.1(160)=176
25 x=44
100 176
0.25(176)=44/month
Answer:
the slope represents the cost for each hour it takes to repair the machine.Step-by-step Answer:
We are given that the cost of a service call to fix a washing machine can be expressed by the linear function
Where
y=Total cost of a service to fix the machine.
x=Number of hours takes to fix the machine
We have to find that slope in this function what represents.
General equation of line is given by
Where m=Slope of line
c=y- intercept
Comparing the general equation with the given function
We get m=45,c=35
m=45 represents the cost for each hour it takes to repair the machine because when number of hours multiplied by 45 then we get total cost of x hours.
Hence, the slope represents the cost for each hour it takes to repair the machine.
