Would this be correct? I simplified x to 8x.

Arte-miy333 [17]

$\sqrt[3]{8x^3}\implies \sqrt[3]{2^3x^3}\implies \sqrt[3]{(2x)^3}\implies 2x~\hfill y=\stackrel{m}{2} x\stackrel{b}{+8} \\\\[-0.35em] ~\dotfill\\\\ \boxed{A}\qquad m = 2\\\\ \boxed{B}\qquad b = 8\\\\ \boxed{C}\qquad 0=2x+8\implies -8=2x\implies \stackrel{~\hfill y-intercept}{\cfrac{-8}{2}=x\implies -4=x}$

-3x 2 + 2y 2 + 5xy - 2y + 5x 2 - 3y 2 if x=2 and y=-1

Vladimir [108]

If $x=2,y=1$ the formula becomes:
$-3(2)^2 + 2\times1^2 + 5(2) - 2 + 5(2)^2 - 3\times1^ 2\\=(-12+2)+(10-2)+(20-3)\\=(-10+8)+17\\=-2+17\\=15$
