Answer:
Two solutions (-4,-7) and (4,7)
Step-by-step explanation:
x = y + 3
x*y = 28
(y+3)*y=28
y^2+3y-28=0
(y+7)(y-4)=0
y=-7, y=4
x=-4, x=7
Answer:
x=-4
Step-by-step explanation:
x+12+x+16=20
2x=20-28
x=-8/2
x=-4

Answer: That is the orgin.
Step-by-step explanation:
I think the answer is this
2x-4x+1=0

Subtract 1 both sides
-2x=-1
Divide by -2 both sides
x=-1/2
The fourth terminal. The unit circle you move around counterclockwise and 8pi over 4 is 2pi, which is also zero. So the quadrant would be just 45 degrees below 2pi and in quadrant 4
