If x= -2 and y=5, find the value of the expression 5y-3x2

Which facts are true for the graph of the function below? check all that apply. f(x) = log8 x. (30 points pls )

Select the correct answer from the drop-down menu. subtracting 3xy^2 from 8xy^2 gives the same result as the expression. [tex]3xy ^{2} - 8xy ^{2} [/tex][tex] { - 7xy}^{2} - {2xy}^{2} [/tex][tex] {7xy}^{2} - {2xy}^{2} [/tex]

Can someone me and plz do the problem
