6. itcostjustin$100. a tax of 7% of his monthly bill. after 6 months, justin had paid a total of $350.38 for his access fee, taxes, and his initial installation. what is justin’s monthly access fee not including taxes?

The known is

       $100 install

       6 months

       $350.38 total

       7% of bill in taxes

Unknown

         monthly access fee = f

100 + 6( f + 0.07f ) = 350.38

100 + 6f + 0.42f = 350.38

100 + 6.42f = 350.38

- 100                - 100

6.42f = 250

6.42       6.42

f = $39 monthly cable fee

the equation of the parallel line would be y = 2x + 9

step-by-step explanation:

to start we need to find the slope of the original line. we can do that by looking at the coefficient of x, which is 2

since the slope of the original line is 2 and parallel lines have the same slope, we know the new line will also have 2 slope. now we can use that along with the point given in point-slope form to get the find equation.

y - y1 = m(x - x1)

y - 5 = 2(x + 2)

y - 5 = 2x + 4

y = 2x + 9
