Lets find the slope of the graph for Jennifer's record. THe slope represents her rate.

Slope = (y2 - y1) / (x2 - x1)

Lets use the first two points.

Slope = (8 - 5) / 64 - 40)

= 3 / 24

= 1 / 8

Use the second and third points.

Slope = (10 - 8) / (80 - 64)

= 2 / 16

= 1 / 8

Last points.

Slope = (12 - 10) / (96 - 80)

= 2 / 16

= 1 / 8

The slopes are constant.

Now we compare the slopes. Use the LCD to compare fractions.

1 / 9 = 8 / 72

1 / 8 = 9 / 72

9 / 72 > 8 / 72

Jennifer has the faster training rate. She can cover more distance in less time than Patrick can.

How are fractions divided the right way?

Lady_Fox [76]

You would keep the first fraction the same , turn the division sign into a multiplication sign , and flip the 2nd fraction upside down.

10/14 ÷ 7/16

10/14 x 16/7= 80/49 = 1 31/49

P(t) = 2ť + 10 n(t) = 4 What’s the function (p+n) (t)?

Evgen [1.6K]

Answer:

$\boxed{\sf (p + n)(t) = 2t + 14}$

Given:

$\sf p(t) = 2t + 10 \\ \sf n(t) = 4$

To find:

$\sf (f + g)(x) = f(x) + g(x)$

Step-by-step explanation:

$\sf \implies(f + g)x = f(x) + g(x) \\ \\ \sf \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = (2t + 10) + ( 4) \\ \\ \sf \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 2t + 10 + 4 \\ \\ \sf \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 2t + 14$
