How do you solve -9+11+(-9)+12

So basically, what you want to do, is just add or subtract everything together.

Think of -9 as a number 9 to the left of a number line, and then you're adding 11 units, moving -9 11 times to the right. Once you do this, you get 2. Now, adding negative 9 is the same thing as moving 2 9 times to the right. Once you do that as well, you'll get -7. And then just move -7 12 units to the right on the number line and you'll get 5.

Haha that was a really bad explanation, but hope I helped!

Solve.
Snezhnost [94]

Answer:

v = -1

Step-by-step explanation:

First, you will need to solve it step-by-step:

(4v − 9)(1 + v) = 0

Next, you need to simplify both sides of the equation:

4v(2) − 5v − 9 = 0

Now, factor the left side of equation:

(4v − 9)(v + 1) = 0

The last thing you need to do is to set all of the factors to equal to zero:

4v − 9 = 0 or v + 1 = 0

So, that means that you answer:

v=9/4 or in your case, v = −1

Which system of equations is represented by the graph?
o-na [289]
The answer is the third option, which is:
<span> y = x^2 + 5x + 3 
 6x + y = −27
 The explanation is shown below:
 1. When you solve this problem you have the following solution:
 x=-6
 y=9

 x=-5
 y=3

 2. As you can see the solution corresponds with the graph shown above.
 3. You can give value to the variable x of the first equation and values to the x of the second equation, and plot each point obtain. You will see that the parabola and the line, touch each other at the points (-5,3) and (-6,9)</span>
