Answer:
32
Step-by-step explanation:
x^2 + 4y = 16 + 20 = 32
Just do substitution.

Answer:
Step-by-step explanation
First, let's remember the equation for point-slope form and how to find the 'm' value:
Now plug your m value and (x1, y1) into point-slope form:
Answer: 
or 
Step-by-step explanation:
Step 1: Factor left side of equation: 
Step 2: Set factors equal to 0: 
or 
Get your answer: or
-3 = x/-9
To make this easier, I'll put it in normal numbers
(-3 = x/-9) -1
3 = x/9
Multiply both sides by nine to take out the division.
27 = x

A pair of perpendicular lines would be line CF and line AJ.
Line BC and line AJ are NOT perpendicular because when a pair of lines are perpendicular, all angles become 90 degrees. It is obvious, in the case, if you were to slide line BC on top of line AJ, the angles will not equal 90 degrees.
