A phone company offers two monthly plans. Plan A costs $12 plus an additional $0.16 for each minute of calls. Plan B costs $29 p lus an additional $0.12 for each minute of calls.
For what amount of calling do the two plans cost the same?
What is the cost when the two plans cost the same?
1 answer:
Answer:
Step-by-step explanation:
<u>The equation to reflect the monthly plans:</u>
Plan A f(x) = 0.16x + 12 Plan B g(x) = 0.12x + 29 <u>We need to find the value of x when f(x) = g(x):</u>
0.16x + 12 = 0.12x + 29 0.16x - 0.12x = 29 - 12 0.04x = 17 x = 17/0.04 x = 425 minutes <u>The cost is:</u>

Answer:
A statement that is true about the angle measures of the pieces is that the angle measure of each piece is 72°. This is because there are 360° in a full circle, and if each piece is equal, that means that each piece is a fifth of that. Therefore, the angle measure is 360/5= 72°
First, change it into general form(y=my+b). 3y=6x-1+10 3y=6x+9 y=2x+3 So, the slope is 2, and the y-intercept is 3
