3m squared subtracted by 10m equals（ ）？

I'm assuming we are just simplifying. Since no value for m is given.

Both of those terms share a greatest common factor of m. So we will divide each term by variable m and place it on the outside of the parenthesis of the leftover factored equation.

3m²/m - 10m/m = m(3m - 10)

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571

step-by-step explanation:

i think it will be zero as slope has a formula of difference between initial and final distance divided by itz time interval
