Answer:
y = - 1/2x - 4.5
Step-by-step explanation:
Step 1:
x + 2y = - 9 Equation
Step 2:
2y = - x - 9 Subtract x on both sides
Answer:
y = - 1/2x - 4.5 Divide 2 on both sides

Given:
Triangular prism.
Base area : 37.4 square yards
height : 5 yards
To find the volume of the ramp based on the given figures, we simply multiply the base area by the height.
Volume = base area * height
V = 37.4 square yards * 5 yards
V = 187 cubic yards.
The volume of the triangular prism-shaped ramp is 187 cubic yards.

Suggesting that you want this in standard form, in terms of quadratic equations, you would technically follow a process similar if not almost exactly like the 2 - step equation method with the exception of separating the (x)s and the equations to find x and then plug it in and what-not.
With that being said you would subtract 5 in (x+5) from said 5 in the second equation and -10 in the first equation in order to get 2x^2+7x-15, you would continue to do the same for the x by subtracting it from both ends making the 7x a 6x because there is a 1 at the beginning of each x if there is no number that is shown already. Which finally gives you the equation (y= 2x^2+6x-15)
