<span>-3xy 3 + 7xy 3 + (-xy 3) + (-3xy 3).

First combine like terms:
</span>-3xy 3 + (-3xy 3) + 7xy 3 + (-xy 3)
<span>
-3xy3 +  -3xy3 = -6xy3
7xy3 + -xy3 = 6xy3

The answer is 7xy3 + 6xy3</span>

2+5k=3k-6 i need the steps to solve this . i am struggling to find the answer. can you help me?
Katarina [22]
Ok, so what you're going to do is add the -6 to the other side and combine it with the number 2 making it 8, then you are going to subtract the 5k from the left side and add it to 3k so if you now have a -5k + 3k it would = -2k then you would take the 8=-2k and divide each side by -2 which leaves you with -4=k

Simplify The following equations
Y_Kistochka [10]
<span>mostly collect like terms
use associative property which is
(a+b)+c=a+(b+c)
also -a+b-c=(-a)+(b)+(-c) so you can move them around
and remember that:
you just use a general rule
x+x=2x
x^2+x^2=2x^2
3xy4xy=7xy
3x+4x^2=3x+4x^2
you can only add like terms( like terms are terms that are same name like x or y are differnt, and like terms have same power exg x^2 and x^3 and x^1/2 and such

I will oly put the naswers because I don't have much time

first one: 2a+3b+2c

second one: remember that -(-6c)=+6c so the answer is c-10a-2b

third one: -a-8b-5c

Write an equation in slope intercept form for the line that goes through the point (-2,-5) and (3,5)
Orlov [11]

Answer:

Slope intercept form is y=mx+b

Let’s first find the slope, which is y2-y1/x2-x1

Let’s make the point (-2,-5) our x1 and y1 and let’s make the point (3,5) our x2 and y2.

5+5/3+2

10/5

2 = slope

So far, our equation is looking like this:

y=2x + b

To find the y-intercept (b), let’s plug in one of the points.

Let’s use the point (3,5)

(5)=2(3) + b

5=6 + b

What adds to 6 to equal 5? -1

So, our y-intercept is going to be -1

Finally, our equation is going to look like this:

y=2x-1

Hope I helped!
