Laylah as already spent 3 minutes on the phone, and she expects to spend 1 more minute with every phone call she routes. If she routes 23 phone calls, how much time will Layla have spent on the phone in total?

Step-by-step explanation:

Let x represent the number of phone call that she routes.

Laylah has already spent 3 minutes on the phone and she expects to spend 1 more minute with every phone call she routes. This means that if she routes x phone calls, the total number of time that Layla would have spent on the phone is

3 + x

If she routes 23 phone calls, the total time that Layla would have spent on the phone in total is

3 + 23 = 26 minutes

x=-2

infinite number of lines, so there is an infinite number of equations.

step-by-step explanation:

there are an infinite number of line that passes through the point (-2,5)

x=-2   is one line that passes through the point

y = 5 is another line that passes through the point

(these two lines are perpendicular to each other).

since the number of   numbers are infinite and the slope is the ratio of two numbers,(change in y over change in x) we can have an infinite number of slopes.     our only condition is that it passes through the point (-2,5)

f(x) is the value of the function. b is the value of the function when x equals zero or the y-coordinate of the point where the line crosses the y-axis in the coordinate plane.

step-by-step explanation:
