Answer:

The origin is (0,0) and to plot the points go over on the sideways line (right for positive numbers and left for negative numbers). Crawl over the sideways line and up the up and down line. For negative numbers on the up and down line go down, but for positive go up.

(m3 - 6m2 - 16m + 63) divided by (m - 7)

Arlecino [84]

Therefore( $m^3 -6m^2-16m +63$ )÷ (m-7) $= (m^2 +m-9)$

Step-by-step explanation:

$m^3 -6m^2-16m +63$

$=m^3 -7m^2$ $+m^2 -7m$ $-9m+63$

$= m^2(m-7)$ $+m(m-7)$ $-9(m-7)$

$= (m-7 ) (m^2 +m-9)$

Therefore( $m^3 -6m^2-16m +63$ )÷ (m-7) $= (m^2 +m-9)$

What is 7 / 2/3 in simplest form

galina1969 [7]

To do this we have to do 7 divided by 2/3

The first step to dividing fractions is to turn it into a mutipuacation sentence

7x2/3

Now we want to flip the second fraction over or make it a reciprocal

Our new equation is

7x 3/2 which is equal to 21/2

There are two ways. You may simplify it to 10 1/2 or just leave it as it is

hope this helped!! If you have questions, feel free to ask
