Simplify:
(7b^4)(-9b^2)

The coordinate grid shows points a through k. which points are solutions to the system of inequalities listed below? 2x+ ys 10 2x 4y < 8 oa c, d, k o e, f. g, j oa, c, d, h, k oe, f. g, h, j

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

Last one and the bottom answer choice is y=(x-4)^2+1 you guys!
