Answer:
7) B
22) B
Step-by-step explanation:
7) -4n
The expression must have a negative value
Use three types of examples for n
-4(-1) -4(0) -4(1)
4 0 -4
Only one of these examples results in a negative number, 1.
1 > 0
Substitute n back into the inequality
n > 0 B
22) Use two numbers greater than 0 to represent m and n
ex.) m = 1 n = 2
[tex]\frac{-m}{n}[/tex] = [tex]\frac{-1}{2}[/tex] = -0.5
-0.5 is a rational, negative number. B
Hope this helps :)
