Answer 4

Do you want the graph or the answer to y and x? What are you really asking for? Just to solve?

Answer 5

Simplifying
y = -0.04x2 + 1.3x + 56

Reorder the terms:
y = 56 + 1.3x + -0.04x2

Solving
y = 56 + 1.3x + -0.04x2

Solving for variable 'y'.

Move all terms containing y to the left, all other terms to the right.

Simplifying
y = 56 + 1.3x + -0.04x2

Is this what you're looking for?
