Answer: 195

Step-by-step explanation: Well first you would do 165 divided by 11 to find the rate. Then multiply what you got as your rate by 13. Then you would get 195.

Answer:

Ok, first divide the money by the hours worked to get dollars per hour, $165/11 equals 15, so Lisa makes $15 dollars an hour, 13 hours times $15 dollars per hour equals $195 for 13 hours.

Answer:

(1.13, 7.74) and (-4.13, 18.26)

Step-by-step explanation:

This can be solved in two ways:  mathematically and graphically.

<u>Graphing</u>

Plot both lines and find where they intersect.  See the attachment.

The intersection points are (1.13, 7.74) and (-4.13, 18.26)

<u>Mathematical</u>

y + 2x = 10

y = 10 - 2x

y = 3x² + 7x - 4

10 - 2x = 3x² + 7x - 4

3x² + 9x - 14 = 0

Solve this using the quadratic equation:

x = 1.13 and -4.13

Use these two values of x to find y:

y = 10 - 2x

y = 10 - 2(1.13)

y = 7.74

y = 10 -2x

y = 10 -2(-4.13)

y =  18.26

The two points are:

(1.13, 7.74) and (-4.13, 18.26)

Evaluate each expression if r= −3, s=4, and t= −7.
saul85 [17]

Answer:

a. 5

b. -1

c. 132

Step-by-step explanation:

Given:

r =-3, s = 4 and r = -7

\sqrt{s} +|r| \\ \sqrt{4} +|-3| \\ 2 +3 \\ 5

\frac{s -r}{t} \\ \frac{4 -(-3)}{-7} \\ \frac{4 +3}{-7} \\ \frac{7}{-7} \\ -1

2s^3 +r -t \\ 2(4)^3 +(-3) -(-7) \\ 2(64) -3 +7 \\ 128 -3 +7 \\ 132
