Iphone company offers to monthly plan plan a cost $21 plus an additional $0.17 each minute of calls play b $26 in additional 0.12 $ for each minute of calls for what amount of calling do the two plans cost the same

100 minutes

Step-by-step explanation:

Let x = # of minutes

Company A: y = 21 + .17x

Company B: y = 26 + .12x

Set the equations = to each other.

21 + .17x = 26 + .12x

.17x = 5 + .12x

.05x = 5

x = 100

y-y1=4(x-x1)

step-by-step explanation:

this is point-slope form since you only have 4 as the slope it goes in place of m

hope this : )

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
