Answer:

24

Step-by-step explanation:

8-(3x-2)2

Multiply 3 and -2

8-(3(-2)-2)2

You should get 8-(-6-2)2

Subtract -6 from 2. You should get -8

8-(-8)2

Since there are 2 negatives your 8 will become a positive and your subtraction sign will become a addition sign.

8+8*2

You should get 8+16

16 plus 8 equals 24.

Therefore, your answer is 24

If 16 x/20 then x equal
PtichkaEL [24]
The answer is 320.

If 16 = x / 20, then x = 320

Multiply both sides of the equation by 20:
20 * 16 = 20 * x / 20

Multiply the terms on the left side of the equation:
320 = 20x/20
320 = 20/20 * x

Simplify the rigth side of the equation:
320 = 1 * x
320 = x

Therefore, x = 320

PLZZZZ HURRY ILL GIVE BRAINLEST POINTS PLZZZZ I NEED A 100% ON THIS TEST
yuradex [85]

Answer:

y=2/3-1

Step-by-step explanation:

Two coordinate points are (-3,-3) and (3,1). If you use Y2-Y1/X2-X1, you will find the slope. Then use y=mx+b to find the equation.

More detailed:

1+3/3+3 ** It is + because when there are minus signs it turns to a plus

4/6 Then simplify it

2/3

Now that the slope is found, we need to use y=mx+b

(I used the point (3,1))  1=2/3(3)+b

                                    1=2+b

                                    -1=b

I hope this is helpful gl on the test! :)
