Answer:
8x^3-7x^2-11x+9
Step-by-step explanation:
(8x^3-5x-1)-(7x^2+6x-10)
remove unnesasary ( )
8x^3-5x-1 -(7x^2+6x-10)
the distribute
8x^3-5x-1 -7x^2-6x+10
combine like terms
8x^3-11x+9-7x^2
use the communative property to reorder the equation
8x^3-7x^2-11x+9

Answer:
graphs left to right have a=1, a=0.25, a=-1
Step-by-step explanation:
A negative value of 'a' makes the parabola open downward, so the rightmost graph goes with a=-1.
A value of 'a' less than 1 flattens the graph, so the middle graph goes with a=0.25.
A value of 1 gives a standard open-upward parabola, corresponding to the leftmost graph.
