Answer:

y-4 = 3(x-1)

Step-by-step explanation:

First you will need to find the slope of the two points.

You can do this by using the slope formula:

m=(y_{2}-y_{1} ) /(x_{2}-x_{1})

Which would equal :

\frac{7-4}{2-1} =\frac{3}{1} =3

You would also have to know what point-slope form is:

y-y_{1}=m\left(x-x_{1}\right)

Now insert your points, and the slope.

y-4 = 3(x-1)

Easy + brainliest<br><br> 2x(^3) + 10x(^2) − 4x(^2)y − 20xy<br><br> factor this pls, (show all work)
Dimas [21]

Answer:

Answer:

2x • (x2 - 2xy + 5x - 10y)

Step-by-step explanation:

Step  1  :

Equation at the end of step  1  :

(((2•(x3))+(10•(x2)))-(22x2•y))-20xy

Step  2  :

Equation at the end of step  2  :

(((2 • (x3)) +  (2•5x2)) -  22x2y) -  20xy

Step  3  :

Equation at the end of step  3  :

((2x3 +  (2•5x2)) -  22x2y) -  20xy

Step  4  :

Step  5  :

Pulling out like terms :

5.1     Pull out like factors :

 2x3 - 4x2y + 10x2 - 20xy  =

2x • (x2 - 2xy + 5x - 10y)

Final result :

2x • (x2 - 2xy + 5x - 10y)
