Divide off -3 from both sides, that leave you with:
n + 5 = -4
Subtract the 5 to the other side
n = -9
421875 cm because you take the 75 and square it to the 3rd power
Answer: A) 3x + 5x - 4 = 1
<u>Step-by-step explanation:</u>
The second equation is y + 4 = 5x. Solve this equation for y by subtracting 4 from both sides. --> y = 5x - 4
Now replace "y" in the first equation with "5x - 4".
3x + y = 1
--> 3x + (5x - 4) = 1
For this case we have the following inequality:

We must find an ordered pair of the form
that meets the inequality.
Example:
<em>Pair 1: </em>

This pair does not satisfy the inequality.
<em>Pair 2:</em> 

This pair satisfies the inequality!
Thus, the pair
meets the inequality.
