Use a form of the distributive property to rewrite the given algebraic expression without parentheses. 2(3x-3)

guajiro [1.7K]

Answer:

6x-6

Step-by-step explanation:

The Distributive property says that a(b+c) = ab+ac

In my example you distribute the value on the outside to the things on the inside

In your problem you have a two on the outside that needs to be distributed to a 3x and a -3

1) 2 multiplied by 3x equals 6x giving you the first part of your answer!

2) 2 multiplied by -3 equals -6 giving you the second part of your answer!

Don't forget that there is a - sign between the 3x and 3, don't drop it!

Put the two values together to get 6x-6

Let me know if you have any further questions :)

AB has a vértices at (-5,1) and (-3,7). After a transformation, the image had endpoints at (3,-1) and (5,5). Describe the transf

Scrat [10]

That looks like a translation; let's check. We have

A(-5,1), B(-3,7), A'(3,-1), B'(5,5)

If it's a translation by T(x,y) we'd have

A' = A + T

B' = B + T

so

T = A' - A = (3,-1) - (-5,1) = (8,-2)

and also

T = B' - B = (5, 5) - (-3, 7) = (8,-2)

They're the same so we've verified this transformation is a translation by (8,-2), eight right, two down.

Put this into Slope Intercept Form<br> x + 6y = –6

mel-nik [20]

Answer:

$y=-\frac{x}{6} -1$

Step-by-step explanation:

Hi there!

We are given the following equation:
x+6y=-6

And we want to convert it into slope-intercept form

Slope-intercept form is known as y=mx+b, where m is the slope and b is the y intercept

The equation is currently in standard form, which is ax+by=c, where a, b, and c are integer coefficients

Notice how in standard form, both the terms that contain x and y are on one side, but in slope-intercept form, y is by itself on one side

So essentially, in order to convert from standard form to slope-intercept form, we need to solve for y

Here is our equation again:

x+6y=-6

Start by subtracting x from both sides

x+6y=-6

-x -x

_______________

6y=-x-6

Now divide both sides by 6

$y=-\frac{x}{6} -\frac{6}{6}$
We can simplify the fractions to become:

$y=-\frac{x}{6} -1$
Hope this helps!
