2x + y = x - y - 3 = 6
Add 3 to everything
2x + y + 3 = x - y - 3 + 3 = 6 + 3
2x + y + 3 = x - y = 9
2x + y + 3 = 9
2x + y = 6 = x - y
Add y to everything
2x + 2y = 6 + y = x
Since x = 6 + y substitute every x with 6 + y
2(6 + y) + 2y = x
12 + 4y = x
This is as simplified as I can get and then just place 12 + 4y into every x in the original problem then solve
X = -1/2 (negative)
y = - 1.8 (negative)
so It's in Quadrant 3
Answer:
c
Step-by-step explanation:
Answer:
cos(x)=0.6
Step-by-step explanation:
cos(x) represents the horizontal distance of the unit vector
sin(x) represents the vertical distance of the unit vector (0.8)
tan(x) represents the distance on the tangent line from the point to the x-axis
cot(x) represents the distance on the tangent line from the point to the y=axis
