Answer:

Add 8 to both sides and then multiply each side by 2

Step-by-step explanation:

Since 8 is negative, we need to add 8 to move 8 to the other side and eliminate it from its original side.

Since x is being divided by 2, we need to multiply by two to isolate x.

Lets solve the equation and see the steps so it is easier.

x/2 - 8 = 14

Add eight to both sides of the equation to get x/2 alone.

x/2 - 8 + 8 = 14 + 8

x/2 = 22

Multiply both sides by two to get x alone.

x/2 • 2 = 22 • 2

x = 44

Now we see the steps we made. Lets look at the choices. Your answer is the third choice. I hope this helps!

Yeah i don't know how to answer this....
Deffense [45]

Answer:

y = \sqrt{16} x

that is equal to  y = 4x

\sqrt{16} = 4

when graphing (x,y) the x is the horizontal value of the point (east west)

and the y in the vertical (north south) ....

if you have y = x it would be a 45 degree line that goes from the lower left to the upper right....

if you compare the red line  the point  1,1  (y=x) versus 1,4 (y=4x) in the blue line you will see that it is "stretched" upward

What happens when you see 42 (17 – 15) / (3 + 1) – 5 ? What do you do first? The mnemonic PEMDAS or Please Excuse My Dear Aunt S
valina [46]

Answer:

The operations done first are:

a)  42 (17 – 15) / (3 + 1) – 5 ; (17 -15) or (3 + 1) (parenthesis) are done first

b)  42 (17 – 15) / (3 + 1) – 5 ; 7 × 2 (multiplication) is done first

Step-by-step explanation:

from the mnemonic PEDMAS, the order of operations are: Parentheses, Exponents, Multiplication/Division, Addition/Subtraction.

hence in the first expression : 42 (17 – 15) / (3 + 1) – 5, the parenthesis (bracket is simplified first as follows:

(17 - 15) = (2) ;  and (3 + 1) = (4) ;  hence the expression will be simplified as follows: 42 (2) / (4) - 5.

Next, since there is no exponent in the expression, Multiplication follows:

42 (2) = 42 × 2 = 84 ; hence he expression becomes: 84 / 4 - 5

Next division follows : 84/4 = 21, therefore the expression becomes

21 - 5.

Finally, subtraction follows : 21 - 5 = 16

b)  5 + 7 x 2 - 9;

first, multiplication is done: 7 × 2 = 14, hence the expression becomes :

5 + 14 - 9.

Next in the order is addition : 5 + 14 = 19, hence, the expression becomes:

19 - 9.

Finally, subtraction follows: 19 - 9 = 10
