Which inequality is true?
DiKsa [7]

Answer:

C. 5\pi > 15

Step-by-step explanation:

In the given series of inequalities, the inequality sign determines the final outcome.

A. 4\pi - 2 < 10

4\pi < 12

\pi < 3

Since \pi < 3, then the inequality is false

B. \pi + 9 < 12

\pi < 3

Since \pi < 3, then the inequality is false

c. 5\pi > 15

\pi > 3

Since \pi > 3, then the inequality is true

D. 6 > 2\pi

3 > \pi

Since \pi < 3, then the inequality is false

Thus, the only inequality that is true is option C.

Jane has a pre-paid cell phone with Splint. She can't remember the exact costs, but her plan has a monthly fee and a charge for
yan [13]

Answer:

The costs of the plan are $0.15 per minute and a monthly fee of $39

Step-by-step explanation:

Let

x ----> the number of minutes used

y ----> is the total cost

step 1

Find the slope of the linear equation

The formula to calculate the slope between two points is equal to

m=\frac{y2-y1}{x2-x1}

we have the ordered pairs

(100,54) and (660, 138)

substitute

m=\frac{138-54}{660-100}

m=\frac{84}{560}=\$0.15\ per\ minute

step 2

Find the equation of the line in point slope form

y-y1=m(x-x1)

we have

m=0.15\\point\ (100,54)

substitute

y-54=0.15(x-100)

step 3

Convert to slope intercept form

Isolate the variable y

y-54=0.15x-15\\y=0.15x-15+54\\y=0.15x+39

therefore

The costs of the plan are $0.15 per minute and a monthly fee of $39
