Answer to Question #162127 in Algebra for Will

Question

Kellie and Maverick are solving the same system of of equations by graphing

y-3x=9

y= 2x²-4x + 12

Kellie believes there is one solution at (3,18). Maverick believes there are two solutions at (3,18) and (0.5, 10.5). Who is correct?

Answer 1

According to the graph y - 3x = 9

Represented by the straight line

y = 2x² -4x + 12

represented by the curve line where they both intercept at ( 3, 18 ) and ( 0.5, 10.5 ). So there are two solutions at ( 3, 18 ) and (0.5, 10.5 ).

So Meverick is correct.
