Answer:
{x,y}={-8,-2}
Step-by-step explanation:
[1] x = 2y - 4
Plug this in for variable x in equation [2]
[2] 7•(2y-4) + 5y = -66
[2] 19y = -38
Solve equation [2] for the variable y
[2] 19y = - 38
[2] y = - 2
By now we know this much :
x = 2y-4
y = -2
Use the y value to solve for x
x = 2(-2)-4 = -8

Answer:
Tationia Rolon
Step-by-step explanation:
I think its C because the median is the number in the middle
Answer:
A
Step-by-step explanation:
equation of the line graphed
(y-4)/(2-4) = (x+6)/(0+6)
(y-4)/(-2) = (x+6)/6
y-4 = (x+6)/-3
y = (x+6)/-3 +4
y = (x+6-12)/-3
y = -1/3x + 2
so the answer is A
Mean absolute deviation of the set is 1.6
