-8 ➗ 2/7
First you have to make the -8 a fraction

-8
—
1

Then you multiply it
-8✖️7
1✖️2

Then you’re left with -56/2
Then you do:
-28✖️2
1✖️2

Then you’re left with -28/1

So your answer is -28

Hope this helps! :3

6x + 3 (2x) - 7 - 2³ Please include th steps to solving it.

Alchen [17]

Answer:

24x-15

Step-by-step explanation:

Let's do this together with a step-by-step explanation!

First we need to make sure we remember that there are appropriate ways on how to solve these. LIKE PEMDAS.

6x + 3 (2x) - 7 - 2³

Let's multiply the 3 and 2x together.

6x + 6x - 7 - 2³

Now let's do the exponent

6x + 6x - 7 - 8

Now let's add everything together! But remember only common variables can be added together.

24x - 15 is the answer.

You can no longer break anything down.

I really hope this helped you!

Write an equation in slope-intercept form that passes through each pair of points. (0, 1) (-3, 1)

lina2011 [118]

Answer:

$y = \frac{0}{ - 3} + b$

Step-by-step explanation:

Slope intercept formula is y=mx+b

(m) is slope

(b) is the y intercept

We'll find slope first.

slope formula is

$\frac{y2 - y1}{x2 - x1}$

y2 and x2 are the y and x values of the second equation and y1 and x2 are the y and x values of the first equation.

So we just put the given values into our equation.

$\frac{1 - 1}{ - 3 - 0}$

Simplify

$\frac{0}{ - 3}$

Now we put this into our y=mx+b

y=0/-3x+b

now we need the (b)

to do this we take the values of one of the coordinates (doesn't matter which) and replace the (y) and (x) in our equation with them.

$y = \frac{0}{ - 3} x + b$

$1 = \frac{0}{ - 3} (0) + b$

Solve

1=0+b

b=1

Put this in our formula

$y = \frac{0}{ - 3} + 1$

Hope this helps! If you have any questions on how I got my answer feel free to ask. Stay safe!
