One phone company charges a flat fee of $35, plus $0.15 for each minute. the other phone company charges a flat fee of $20, plus $0.25 for each minute. for how many minutes, m, do the companies charge the same amount?

0.15m+35=0.25m+20

Step-by-step explanation:

(x+3)(x+7)

step-by-step explanation:

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571
