Pls only answer if yk it i’m giving correct answer brainliest! :)

-3+10x^3-5x^2

997-25x

Step-by-step explanation:

That is the simplest from of the equation.

I Hope This Helps :)

b. 2

step-by-step explanation:

the slope of a line =δy/δx

δy= y₂-y₁

δx= x₂-x₁

therefore, using the points (-2,-3)   and (3,7) we can calculate gradient as follows:

m=(7--3)/(3--2) (a number minus a negative number the sign changes to a plus)

m=(7+10)/(3+2)

=10/5

=2

what is the original number? you forgot to add it.
