Answer:

Step-by-step explanation:

-3.1+7-7.4x=1.5x-6(x-1.5)

We move all terms to the left:

-3.1+7-7.4x-(1.5x-6(x-1.5))=0

We add all the numbers together, and all the variables

-7.4x-(1.5x-6(x-1.5))+3.9=0

We calculate terms in parentheses: -(1.5x-6(x-1.5)), so:

1.5x-6(x-1.5)

We multiply parentheses

1.5x-6x+9

We add all the numbers together, and all the variables

-4.5x+9

Back to the equation:

-(-4.5x+9)

We get rid of parentheses

-7.4x+4.5x-9+3.9=0

We add all the numbers together, and all the variables

-2.9x-5.1=0

We move all terms containing x to the left, all other terms to the right

-2.9x=5.1

x=5.1/-2.9

x=-1+1/1.31818181818

THIS IS UR ANSWER... THANK YOUU

What is the slope of the line passing through the points (−3, 4) and (2, −1) ?

diamong [38]

Hey there!

You can find the slope by using this equation:

$\frac{y_2-y_1}{x_2-x_1}$

It doesn't matter what order you use the points in as long as the x's and y's are in the right place.

$y_2=-1 \\ y_1=4 \\ x_2=2 \\ x_1=-3$

Just plug your numbers into the equation and solve.

$\frac{-1-4}{2-(-3)}$
$\frac{-5}{5}$
$-1$

The slope is –1.

Hope this helped you out! :-)
