Step-by-step explanation:
need to find the halfway point (average) between -0.75 and 0.25 (same as 1/4)

Answer:
The answer is the first choice, x < −4.
Step-by-step explanation:
Let's solve your inequality step-by-step.
2x−2>4x+6
Step 1: Subtract 4x from both sides.
2x−2−4x>4x+6−4x
−2x−2>6
Step 2: Add 2 to both sides.
−2x−2+2>6+2
−2x>8
Step 3: Divide both sides by -2.
x<−4
X^2-9=0 add 9 to both sides
x^2=9 take the square root of both sides
x=±3
