For 1- 4 all you have to do is multiply the numbers.

An easier way to write the same equation out would be to add multiplication signs. For example:

1. -2*3 is the same as (-2)(3)

When there are two parentheses next to each other without a sign in between, that means multiplication.

6-9 can also all be converted to be  a whole number, which is what it want you to do.

11 and 12 is where you need to multiply and then add or subtract after you multiply.

Also, for 13 and 14, both the fractions can be converted to be a whole number, so you should turn them into whole numbers first and your life will be a lot easier.

And 15 is also the same thing as 11 and 12.

Extra Help: When you have two negative numbers, the answer will end being a positive and when there are two positive it will remain a positive, and a negative and positive number will be a negative.

Choose the graph that solve the following system x-4y=2 3x+2y=6
Elanso [62]
X - 4y = 2.....multiply by -3
3x + 2y = 6
-------------
-3x + 12y = -6 (result of multiplying by -3)
3x + 2y = 6
------------add
14y = 0
y = 0

3x + 2y = 6
3x + 2(0) = 6
3x = 6
x = 6/3
x = 2

solution is (2,0).....so the graph that has the two lines intersecting (crossing) at (2,0) is gonna be ur graph

Answer:

y = -2x - 5

Step-by-step explanation:

<u>1) Find the slope of the line.</u>

The slope of the original line is the same as the slope of the parallel line.

Slope formula:

m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}}

In this case you can choose any 2 set of points on the table.

m = \frac{4 - 2}{-3 - (-2)} = \frac{4 - 2}{-3 + 2} = \frac{2}{-1} = -2

So the slope of the line is -2

<u>2) Use the point-slope formula to find the equation of the line.</u>

Point-slope formula:

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

Now plug in the point (0, -5) and the slope -2 into the equation.

y - (-5) = -2(x - 0)

y + 5 = -2(x - 0)

To solve the equation first apply the distributive property.

y + 5 = -2x + 0

y + 5 = -2x

Next, subtract 5 from sides.

y = -2x - 5

You know have your equation in point-slope form!
