Answer:
Step-by-step explanation:
we have
This is a compound inequality
Remember that
A compound inequality i can divide in a system of two inequalities
so
-----> inequality A
---> inequality B
step 1
Solve the inequality A
Multiply by -1 both sides
Divide by 5 both sides
Rewrite
The solution of the inequality A is the interval ----> (-3.2,∞)
step 2
Solve the inequality B
Multiply by -1 both sides
Divide by 5 both sides
The solution of the inequality B is the interval ----> (-∞, 10)
step 3
Find the solution of the compound inequality
(-3.2,∞) ∩ (-∞, 10)=(-3.2,10)
All real numbers greater than -3.2 and less than 10
