Which of the following is not a way to represent the solution of the inequality 7 − 9x − (x + 12) less than or equal to 25?
2 answers:
Answer:
A) x greater than or equal to −3
Step-by-step explanation:
We have the following inequality:
7 − 9x − (x + 12) ≤ 25
Solving the inequation, we have:
7 − 9x − x - 12 ≤ 25
-10x ≤ 30
-x ≤ 3
x≥-3
Therefore the result is option A) x greater than or equal to −3
Answer:
B.
Step-by-step explanation:
7-9x - (x+12) ≤ 25
7 - 9x - x - 12 ≤ 25
-10x - 5 ≤ 25
-10x ≤ 25 +5
x ≥ 30/-10
x ≥ -3.
So, the incorrect answer is B.
