Answer:
- x + y ≤ 25
- 1.75x + 2.50y ≤ 75
Step-by-step explanation:
- Paperback books = x
- Hard cover books = y
<u>Number of books:</u>

The system above is the one we need
first you divide14 and 5 and you get 2.8 then you turn 2.8 into 2 8/10
2 8/10 is your answer
Answer:
y = -2/3x - 2
Step-by-step explanation:
Step 1: Find slope <em>m</em> of perpendicular line
<em>Simply take the negative reciprocal of the given line</em>
m = -2/3
y = -2/3x + b
Step 2: Find <em>b</em>
6 = -2/3(-12) + b
6 = 8 + b
b = -2
Step 3: Rewrite perpendicular equation
y = -2/3x - 2
The fromula of a slope:
We have the points 
and 
Substitute:
<h3>Answer: slope is undefined.</h3><h3 />
It's a vertical line:
