What are the integer values of x which satisfy the inequality -1 < 3 -2x \(\leq\) 5?
The correct answer is D. -1, 0, 1
To solve the inequality \(-1 < 3 - 2x \leq 5\), we will break it down into two separate inequalities:
1. \( -1 < 3 - 2x \)
2. \( 3 - 2x \leq 5 \)
Solve each inequality separately:
1. \( -1 < 3 - 2x \)
Add \(2x\) to both sides:
\( 2x - 1 < 3 \)
Add \(1\) to both sides:
\( 2x < 4 \)
Divide by \(2\):
\( x < 2 \)
2. \( 3 - 2x \leq 5 \)
Subtract \(3\) from both sides:
\( -2x \leq 2 \)
Divide by \(-2\) (remember to reverse the inequality when dividing by a negative number):
\( x \geq -1 \)
Now, combine the solutions from both inequalities:
\( -1 \leq x < 2 \)
This means the integer values of \(x\) that satisfy the original inequality are -1, 0, and 1.
