Given f(x)=-6x-1 and g(x)=x^3,choose the expression for (f g)(x)

a.-18x^3-3
b.-6x^3-1
c.-6x^3-1x^3
-1)^3

When the solutions to each of the two equations below are graphed in the xy-coordinate plane, the graphs of the solutions intersect at two places. write the y-cordninates of the points of intersection in the boxes below in order from smallest to largest. y=2x y=x^2-3

Is this a polynomial function? i need to know asap

The linear combination method is applied to a system of equations as shown. 4(.25x + .5y = 3.75) → x + 2y = 15 (4x – 8y = 12) → x – 2y = 3 2x = 18 what is the solution of the system of equations? (1,2) (3,9) (5,5) (9,3)
