x=2 from cross multiplying.
Answer:
A. (1.55, 2)
Step-by-step explanation:
The formula to apply when finding the midpoint of a segment where the coordinates of the end points are given is;

where (x₁,y₁) and (x₂,y₂) are the coordinates of the end points
Given;
x₁= -0.4 ,y₁=2.5, x₂=3.5, y₂=1.5 then applying the formula for midpoint

If you are looking to write an inequality equation that models this situation, then the answer would be:
. The "at most" signals to use the less than or equal to sign.
Answer:
x = 3 or -3
Step-by-step explanation:
So you have the equation x² - 9 = 0
Move the 9 to the other side: x² = 9
Then take the square root of both sides:
= ±
x = ±
= ±3
x = 3 or -3
