which number line shows the solutions to $\frac{1}{2}x - 2>0$?
which number line shows the solutions to $\frac{1}{2}x - 2>0$?
Answer
Explanation:
Step1: Solve the inequality
Add 2 to both sides of $\frac{1}{2}x - 2>0$, we get $\frac{1}{2}x>2$.
Step2: Isolate x
Multiply both sides by 2, then $x > 4$. On a number - line, the solution of $x>4$ is represented by an open circle at 4 and a ray pointing to the right.
Answer:
The second number - line (the one with an open circle at 4 and a ray pointing to the right) shows the solutions to $\frac{1}{2}x - 2>0$.
