9) Solve by the elimination method.<br><br> x + y = -5<br> x - y = 11
vlabodo [156]
<h2><u>Answer:</u></h2>

x = 3

y = -8

<h2><u>Step-by-step explanation:</u></h2>

x + y = -5

x - y = 11

Since the y's will cancel out, we don't need to modify the two equations in any way.

Now, just add the two equations.

x + x = 2x

y + (-y) = 0

-5 + 11 = 6

2x = 6

Divide by 2.

x = 3

To find y, plug 3 in as "x" in one of the two equations.

3 + y = -5

y = -8

Given the function g(x) = 8x − 2, compare and contrast g(−2) and g(4). Choose the statement that is true concerning these two va
Anit [1.1K]
G(-2) = 8(-2) -2 = -16 - 2 = -18 
g(4) = 8*(4) - 2 =  32 - 2 = 30 
 as you can see 30 is greater than -18 so the answer is C

Which of the following is the solution to the equation - n/2 + 14 = 0 ?
poizon [28]
The answer is n=28;

1. Subtract 14 from both sides (-n/2 = -14)

2. Multiply by 2 on both sides to get rid of the fraction (-n = -28)

3. Divide by -1 to get n by itself (n = 28)

You could also eliminate step three by multiplying by -2 instead of just 2.

Hope this helps!
