Answer:
x=2, y= 4
Step-by-step explanation:
Equation 1 is 2x-4y = -12
Equation 2 is 2x+y = 8
Subtracting the two equations gives -4y-y = -12-8 (The 2x and the other 2x cancel each other out).
Simplifying we get -5y = -20 and y =4
Substituting y =4 into original equation back we get 2x -4(4) =-12
This equals 2x -16 =-12 and 2x = 4 and x =2
Answer:
D=6
Step-by-step explanation:
A quick and easy way to find the distance between these points is to use the distance formula: d= √(x2-x1)^2 + (y2-y1)^2, where (x1,x2) and (y1,y2) are the coordinates of the first and second point. (It doesn't matter which point is (x1,x2) or (y1,y2), just stay consistent)
Plug in the coordinates:
d= √(0-(-6)^2+ (8-8)^2
Simplfy
d=√(6)^2+(0)^2
d=√36
d= 6
Answer:
y=-1/6x-3
Step-by-step explanation:
y-y1=m(x-x1)
y-(-2)=-1/6(x-(-6))
y+2=-1/6(x+6)
y=-1/6x-6/6-2
y=-1/6x-1-2
y=-1/6x-3
