The table and the graph below each show a different relationship between the same two variables, x and y:

x y graph
4 100 x y
5 125 2 60
6 150 4 120
7 175 6 180
8 240

how much more would the value of y be on the graph than its value in the table when x = 12?
20
30
60
70

there are many solutions.

step-by-step explanation:

step 1: simplify both sides of the equation.

4x+6=4x^2+10x−4

step 2: subtract 4x^2+10x-4 from both sides.

4x+6−(4x^2+10x−4)=4x^2+10x−4−(4x^2+10x−4)

−4x^2−6x+10=0

step 3: factor left side of equation.

−2(2x+5)(x−1)=0

step 4: set factors equal to 0.

x=-5/2 or x=1
