When substituting, you want to take the y value from one equation and plug it into the y variable in the other equation to find the x value. When you find the c value, you plug the number into one of the equations to get your y value.

The monthly cost (in dollars) of a long-distance phone plan is a linear function of the total calling time (in minutes). The mon
kkurt [141]

The monthly cost will be $17.14

Step-by-step explanation:

Given that the monthly cost (in dollars) of a long-distance phone plan is a linear function of the total calling time (in minutes) then this can be presented in a table form as;

<u>Time in minutes (x)</u>        <u>Cost in dollars (y)</u>

50                                          $12.55

102                                         $ 17.23

Take the values as ordered pairs to represent coordinates for points that satisfy the linear function

(50,12.55)  and (102,17.23)

Finding the slope of the graph using these points

slope,m=Δy/Δx

m=Δy=17.23-12.55 =4.68

Δx=102-50=52

m=4.68/52 =0.09

Finding the equation of the linear function using m=0.09, and point (50,12.55)

m=Δy/Δx

0.09=y-12.55/x-50

0.09(x-50)=y-12.55

0.09x-4.5=y-12.55

0.09x-4.5+12.55=y

y=0.09x+8.05

So for 101 minutes , the cost will be;

y=0.09*101 +8.05

y=9.09+8.05 = $17.14

Which pyramids with base area B and height h have equal volumes?
Pachacha [2.7K]
Option A:

V = 1/3 * b^2 * h

V = 1/3 * 10.5^2 * 6

V = 1/3 * 110.25 * 6

V = 220.5

Option B:

V = 1/3 * b^2 * h

V = 1/3 * 3.6^2 * 8

V = 1/3 * 12.96 * 8

V = 34.56

Option C:

V = 1/3 * b^2 * h

V = 1/3 * 4.2^2 * 12

V = 1/3 * 17.64 * 12

V = 70.56

Option D:

V = 1/3 * b^2 * h

V = 1/3 * 6^2 * 8.4

V = 1/3 * 36 * 8.4

V = 100.8

I guess it's 'None of the Above'
