Input 3y+11 for x
2(3y+11)-3y=16
6y+22-3y=16
3y= -6
Divide by 3 to isolate y
y=-2
Now for x....
x=3(-2)+11
=-6+11
=5
x=5
Coordinates (5,-2)
Because the x numbers are used more than once it cannot be a function. As for the the relation if its going through the origin then it would be a relation. im going to go with D
Answer:
f(3) = -6
f(-3) = -12
f(0) = -9
Step-by-step explanation:
Substitute each number for x.
f(3) = 3 - 9 = -6
f(-3) = -3 - 9 = -12
f(0 ) = 0 - 9 = -9
Answer:

Step-by-step explanation:
We must develop three equations in three unknowns.
I will use these three:
