Alg 1 pls this is my last question for which algebraic expression is a polynomial with a degree of 2?
a. 4x^3 − 2x
b.10x^2 − x (square root)
c.8x^3 5/x 3 d6x^2 − 6x 5

which  best  describes the transformation from the graph of  f(x) =  x2  to the graph of  f(x) = (x  – 3)2  – 1?   left 3 units, down 1 unitleft 3 units, up 1 unitright 3 units, down 1 unit  right 3 units, up 1 unit

The tiles below are pieces of a normal ecg tracing representing a little less than two heartbeats at a resting rate of 80 bpm. arrange the tiles in their correct order. rank from first to last. do not overlap any tiles.

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