Answer:
number 4 is $223.6 (ADD THE MONEY SYMBOL TOO)
Step-by-step explanation:
44.72 = tip + money she gets per unit of time
then 44.72 x 5 because 5 is how many hours and 44.72 is how much she gets an hour
Answer:
uh... yeah it's best to keep it in simplest form unless if it was involving graphs.
First we take the two points (-7,5) and (-5,9).
Compute the slope:

Then the linear relation may be in the following form

Since the point (-7,5) is on the line, then

The relation is then

.
We check that the other point are on the above line:

W
e have then a linear relation.
To find the area, first, find the length and width. Given, length = 15 units and width = 4 units. The formula to find the area of a rectangle is A = l × w.
Slope = (y2-y1)/(x2-x1) = (8-2)/(3-1) = 6/2 = 3. So the answer is c.
