7 - 2x ≤ 23
A. x ≤ 8
B. x ≥ 8
C. x ≤ -8
d. x ≥ -8
7-2x¡Ü23
Subtracting 7 from each side
-2x¡Ü16
Dividing both sides by -2
x>=-8
(When you divide by a negative, you flip the sign)
okay so the answer is b?
Scotty or Rome -- or whatever your name is -- please do not switch names, especially in the same thread.
No, I didn't say b. It's d.
To solve the inequality 7 - 2x ≤ 23, we need to isolate the variable x. Here is the step-by-step process:
1. Subtract 7 from both sides of the equation: 7 - 2x - 7 ≤ 23 - 7. This simplifies to -2x ≤ 16.
2. Divide both sides of the equation by -2. Since we are dividing by a negative number, the direction of the inequality sign will reverse: -2x / -2 ≥ 16 / -2. This simplifies to x ≥ -8.
Therefore, the correct answer is (d) x ≥ -8.
