<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>

Y=x+2<br> and then you have x=-3 <br><br><br> You also have to use transitive property
tresset_1 [31]
If y = x+2 and x = -3 then we can say that y = -3+2 after replacing the 'x' with -3

From here, we just add -3 and 2 to get -1 which is why y = -3+2 turns into y = -1

So together x = -3 and y = -1

They pair up to form (x,y) = (-3,-1)

Use the Distance Formula to find the distance between (13, 1) and (9,- 4), rounded to the nearest hundredth.
valina [46]

Answer:

  about 6.40 units

Step-by-step explanation:

The distance formula is ...

  d = √((x2 -x1)^2 +(y2 -y1)^2)

For the given points, the distance between them is ...

  d = √((9 -13)^2 +(-4-1)^2) = √((-4)^2 +(-5)^2) = √(16 +25)

  d = √41 ≈ 6.40

The distance between the points is about 6.40 units.
