Solve the system of equations by graphing.
x + y=7
2x-4y=8

Could somebody me with this radical simplification?

Drag the tiles to the correct boxes to complete the pairs. label each function. as even , odd, or neither.

Answer asap! show all work! find the number of complex roots, the possible number of real roots and the possible rational roots of the polynomial function. then, solve for all roots. x^3 + 2x^2 + 3x + 6 = 0
