Plug in guesses till the answer are equal or the same. I started with 10 and 15 because I could compute that quickly and it was very close so then I saw I needed to bring one side up and one side down for the answers to be the same.
C=30+8d Data usage here would be 9= and the program would cost $102
C=60+3d. Data usage here would be14=and this program would cost $102

Write an equation in point-slope form of the line through point J(-8,10) with slope -5.
mafiozo [28]
Point-slope form is y - y1 = m(x - x1). If you apply that point and the slope to the formula (hence the name point-slope), you'd get y - 10 = -5(x + 8).

Hope this helps! :)

REVISE: I accidently put y instead of x in the -5(x + 8) part. It's fixed now.

Virty [35]

Answer:

135

Step-by-step explanation:

m^2 = 3

Cube m^2

(m^2)^3 = 3^3

m^(2*3) = 27

m^6 = 27

Now multiply by 5

5 * m^6 = 5*27

5 m^6 =135
