9514 1404 393

Answer:

  400 minutes

Step-by-step explanation:

The cost of the first plan is ...

  A = 14 + 0.15m . . . . . . . . where m is the number of minutes used

The cost of the second plan is ...

  B = 30 + 0.11m

The costs will be equal when ...

  14 +0.15m = 30 +0.11m

  0.04m = 16 . . . . . . . . . . . . . subtract 14+0.11m from both sides

  m = 400 . . . . . . . . . . . . . . . divide by 0.04

The plans will have the same cost for 400 minutes of calls.

Consider the equation x+4=−2x+19. Let f(x)=x+4and g(x)=−2x+19. The graph of each function is shown. Coordinate plane with the gr
Svetach [21]

The point of intersection of both graphs will have the coordinate (5, 9).

<h3>What is the Point of Intersection of the Graph?</h3>

We are given the functions;

f(x) = x + 4

g(x) = -2x + 19

Now, the point of intersection of both graphs is when both functions are equal which is at f(x) = g(x). Thus;

x + 4 = -2x + 19

x + 2x = 19 - 4

3x = 15

x = 15/3

x = 5

Thus;

f(x) = 5 + 4 = 9

g(x) = -2(5) + 19 = 9

Thus, the point of intersection of both graphs will have the coordinate (5, 9)
