The first one (top left) is a function. Use the vertical line test, if a vertical line crosses the line drawn on the graph twice, then it's not a function.
Answer:
x=(3a+5)/(2a-b)
Step-by-step explanation:
We spread the a to the 2x and -3 first,
2ax -3a= bx+5 5ax
By adding 3a, we pass the -3a over
2ax=bx+5+3aa bx+5+3aa
We'll pass the bx over the bx, then
2ax-bx=5+3aa-bx=5
Now we will party like this on the left side,
5+3a) x(2a-b)=5+3a)
Everything we have to do to find x is to separate both sides by (2a-b)
x=(3a+5)/=(3a+5)/ (2a-b)

Answer:
B: (-7, -8)
Step-by-step explanation:
If the midpoint of (-3, 4) is (-5, -2), then the difference in x is 2, and the difference in y is 6. So to get from the midpoint to b, you have to add two to the x value, and add 6 to the y value. This gets us to the point (-7, -8).
