Answer:

A. -3(5x - 13)

Step-by-step explanation:

When you open the bracket

You have -3 x 5x -3(-13)

Negative negative gives you positive

Then it becomes

-15x + 39

6x-3-11-8x=2 please show work

Ludmilka [50]

Answer: is x = -8

this is how i got it ______

6 x - 3 - 11 - 8 x = 2

(simplify both sides and combine like terms)

(6x + -8x ) + ( -3 + -11) = 2

- 2x + -14 = 2

-2x - 14 = 2

( then you add 14 to both sides)

- 2x - 14 = 2

+14 +14

-2x = 16

( then you divide both sides by -2)

-2x / -2 = 16/ -2

x = -8

ta da!! happy to help!

it made it here. this is for the second one.

( first, we subtract 8n from both sides)

13n + 26 = 8n - 29

-8n -8n

5n + 26 = -29

( then we subtract 26 from both sides)

5n + 26 = -29

- 26 -26

5n = - 55

(after that we divide both sides by 5, we do this to make n alone )

5n/ 5 = -55/ 5

n = -11

Social Security numbers are of the form XYZ - MN - ABCD

Part A:

The first three digits XYZ are referred to as the area number

X is a number 1 - 7 (1, 2, 3, 4, 5, 6, 7)

That means we have 7 choices for X

Y and Z can be any number 0 - 9 (0, 1, 2, 3, 4, 5, 6, 7, 8, 9)

That means we have 10 choices for Y and also 10 choices for Z

So, the number of possible ways are

$7\times10\times10=700$

But we know that the area code 666 has never been used.

So we need to subtract this one from the total.

$700-1=699$

Therefore, the total number of possible area codes is 699.

Answer:

Step-by-step explanation:

So to graph an inverse of the function given we have to switch the x and y values of the function:

So Ill do some points and the rest of the points the same process is applicable.

So our first point is (-1,1)

So our inverse point would be (1,-1)

The second point is (-2,2)

So our inverse point would be (2,-2)

The third point is (-3,3)

So our inverse point would be (3,-3)

Hope this helps!
