To solve this equation, we are going to isolate the variable x.  To do this, we are going to begin by adding x to both sides because this will cancel out the negative x on the right side of the equation.

x + 2 + x = -x + x - 2
When we combine like terms, we get:
2x + 2 = -2
Next, we will try to continue to isolate the variable by subtracting 2 from each side to get the 2x term on the left by itself.
2x + 2 -2 = -2 -2 
When we combine like terms, we get:
2x = -4
Finally, to get x by itself we must divide by 2 to undo the multiplication of the coefficient of the term 2x.
2x/2 = -4/2
When we perform the division, we get:
x = -2
Therefore, x = -2.
We can check this answer by plugging it back into the original equation.  Our answer is verified because 0=0.
Your answer is that x = -2.
Hope this helps!

4. Four friends went on a trip to Mexico. They rented a car for eight days which cost
nlexa [21]

Explanation:

So, I know a lot of people won't do it this way, but this is how I would do it.

First, multiply each expense by eight (eight for the eight days)

$55 x 8 = 440

$25 x 8 = 200

$129 x 8 = 1032

Next, take the three answers and add them together:

440 + 200 + 1032 = 1672

Lastly, divide 1672 by four (four for the four friends)

1672/4 = 418

There you go! Here is your answer. Each friend paid $418

Hope I helped! :D

Please Help!!!!
Angelina_Jolie [31]

Answer:

(4,5)

Step-by-step explanation:

The "feasible region" has vertices (0,0), (7,0), (5,4), and (4,5)

P = 5x + 6y

Plug in each vertices in P  and find out which give maximum value

(0,0) => P= 5(0) + 6(0) = 0

(7,0) => P= 5(7) + 6(0) = 35

(5,4) => P= 5(5) + 6(4) = 49

(4,5) => P= 5(4) + 6(5) = 50

We got maximum P=50 for vertex (4,5)

So  the coordinates of the point that has the maximum value is  (4,5)
