Jean-Paul's error is that he should have written the second equation as h = 4 p + 2.
<h3 />
<h3>How to solve an equation?</h3>
The hardcover book is $8 each and paperbacks for $4 each.
The number of hardcover books, h, sold one day was 2 more than four times the number of paperback books, p, sold that same day.
Therefore,
h = 4p + 2
Hence,
8h + 4p = 160
Therefore, the right equation are as follows:
h = 4p + 2
8h + 4p = 160
Hence, Jean-Paul should have written the second equation as h = 4 p + 2.

Answer:
26 miles
Step-by-step explanation:
Given: 24 miles drive to north.
10 miles drive to east.
Driving pattern form a right angle triangle, which has three leg including straight line distance from starting point (hypotenous).
Now, using Pythogorean theoram to find straight line distance from starting point.
h²= a²+b²
Where, h is hypotenous
a is opposite leg
b is adjacent leg.
⇒h²= 
⇒
⇒
Taking square root on both side, remember; √a²= ±a
⇒
∴ 
Ignoring -26 as distance cannot be negative.
Hence, 26 miles is the straight line distance from starting point.
Answer with explanation:
If Submarine position is 600 feet below sea level, it can be represented in terms of integers as = - 600
Now , it descends 218 feet ,from where it is presently Located.
Descend in terms of integers can be represented as = - 218 feet
Submarine New position or Elevation = - 600 feet + (-218 feet)
= -818 feet
Option A : -818 feet
ANSWER
The domain of the function is

or
[-3,6]
EXPLANATION
The domain of a function refers to the values of x for which the function is defined.
From the graph, we can see that the function begins at (-3,6) and ends at (6,-4).
Therefore the function is defined for x=-3 to x=6.
Hence the domain of the function is

or
[-3,6]
