What is the volume of the figure below?

For f(x)=2x+3 and g(x)=x^2- 8 find (f+g) (x)

Another type of subtraction equation is 16-b=7. explain how you would sole this equation then solve it.

Four equations are shown below.equation 1: y=2*equation 2: y=2x-5equation 3: y=x2 + 6equation 4: tdentify one linear equation and one nonlinear equation from the list.why each equation you identified is linear or nonlinear.nd one nonlinear equation from the list. state a reasonlinear equation
