For this case we must simplify the following expression:

(1-2n) -7n (12-2) =

We solve the operation of the second parenthesis, taking into account that different signs are subtracted and the sign of the major is placed:

(1-2n) -7n (10) =

We multiply:

(1-2n) -70n =

We eliminate the parentheses:

1-2n-70n =

We add similar terms, taking into account that equal signs are added and the same sign is placed:

1-72n

Answer:

The simplified expression is: 1-72n

(This is what I think) First, we minus 720 from her 1000. Now she has $280 left. 280 divided by 28 (the trainer cost) is 10. So, she can spend 10 hours with the personal trainer.

The equation of the line that contains the points (-8, 1) and (0, -5) is
posledela

Answer:

y = -3/4x -5 (G)

Step-by-step explanation:

Find the slope by using the slope formula. (It's hard to format here so look it up)

Basically, it is y2 - y1/x2 - x1

-5 - 1/ 0 + 8

-6/8 = -3/4

The slope is -3/4.

Plug in for y = mx + b

y (y coordinate) = -5

x (x coordinate) = 0

slope (m) = -3/4

-5 = -3/4(0) + b

-5 = 0 + b

b = -5

y = -3/4x -5

atroni [7]

Answer:

I believe the question says "5j + 16 - 12(-9j - 4) - 12j"  I hope I'm correct because I have almost no idea what you typed.

If you did type "5j + 16 - 12(-9j - 4) - 12j" then your answer would be 133j + 52 I believe. You never put how you would like your problem to be solved, so I simplified.

Step-by-step explanation:

Hope this helps.
