Answer: 
You can write this as (-infinity, 7) if you aren't able to use the infinity symbol.

Explanation:
Think of x < 7 as writing 
So x is between negative infinity and 7, excluding both endpoints.
To write in interval notation, we write
The curved parenthesis tell us to exclude the endpoint.
Answer:
15 < x < 31
Step-by-step explanation:
Given 2 sides of a triangle then the third side x is in the range
difference of 2 sides < x < sum of 2 sides , that is
23 - 8 < x < 23 + 8
15 < x < 31
Answer:
x = 2
Step-by-step explanation:
if the line passes through the x axis it means we should use the of x
if it passes through y we should use value of y
in this question perpendicular means at a 90 degree angle
the coordinates is 2,6
so x must be 2
