Answer:
y = 4
Step-by-step explanation:
The given points are on the horizontal line ...
This is the standard-form equation of that line.
67 degrees
All angles in a triangle add up to 180 degrees. So...
23 + x + 90 = 180
113 + x = 180
x = 67 degrees
I will assume you want it in the form of y>mx+b
0.5x-2y>3
0.5x-3>2y
0.25x-1.5>y
f(-3)=4
Substitute x=-3 into the function
f(-3)=(-3)^2-5
f(-3)=9-5
