325 dollars for 13 hours means we have to divide 325 by 13 to get the amount that she charges for every hour. $325 / 13 hours = $25 per hour.
Answer:
try 10x + y = 9/7
Step-by-step explanation:
The answer is D because to find the slope of a line that is perpendicular to another, you have to find the opposite reciprocal. so here the slope would be -1/4. now, take that slope and put it into an equation. like the following:

now to find b you must insert the points into the equation (plug in 4 for x, and 15 for y).

b then equals 16. so, the answer is D.
In any rectangle, the area is given by the product of the width and the length.
Since in this case both dimensions are represented by the correspondent function, you need to multiply the function:
