PLZ HELP I AM ON A TIME LIMIT I WILL GIVE 5x^5 + 4x^4 − 2x^2 + x − 7 if x = −1.

so ya... And remember to use order of op

Which inequality comparing two of the expressions is true when 0.7 < x < 0.9

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]

Solve this equation using substitution. {4x + y = −2} {4x + 6y = 44}
