Use the point-slope form to write an equation of a line through the given points.
Luden [163]

Answer:

y-2=1/3(x+3)

Step-by-step explanation:

m=(y2-y1)/(x2-x1)

m=(4-2)/(3-(-3))

m=2/(3+3)

m=2/6

simplify

m=1/3

y-y1=m(x-x1)

y-2=1/3(x-(-3))

y-2=1/3(x+3)

16r^4t-6r^3t^2+4rt^2=
DochEvi [55]

Answer:

2rt(8r^3-3r^2t+2t)

Step-by-step explanation:

We have been given a polynomial 16r^4t-6r^3t^2+4rt^2 and we are supposed to simplify our polynomial.

We will use factoring to simplify our polynomial. Let us factor out the greatest common factor of all the terms.

We can see that 16, 6 and 4 has 2 as their greatest common factor.

The greatest common factor of r^4, r^3,r is r.

The greatest common factor of t, t^2, t^2 is t.

So the greatest common factor of the terms of our expression will be 2rt.

Let us factor out 2rt from our given polynomial.

2rt(8r^3-3r^2t+2t)

As we can not factor our expression more, therefore, we will get 2rt(8r^3-3r^2t+2t) after simplifying our polynomial.

Step by step solution :

Step  1  :

Equation at the end of step  1  :

 -15ab • (0 -  (2a2 • b3))

Step  2  :

Multiplying exponential expressions :

2.1    a1 multiplied by a2 = a(1 + 2) = a3

Multiplying exponential expressions :

2.2    b1 multiplied by b3 = b(1 + 3) = b4
