Solve by completing the square <br> X^2+12x-13=0
coldgirl [10]
I order to do this question, you need to put the 13 on the right side. So now you have x^2+12x+0=13. Now, take half of 12, and square it. Add this to both sides to get x^2+12x+36=49. Now factor the left side by putting the half of 12 into this blank to get, (x+_)^2=49. Final Answer is,
(x+6)^2=49.

Solve the system of equations.<br><br> 14x + y = −4<br><br> y = 3x^2 − 11x − 4
sveta [45]
You can use substitution here. First, get y alone:

14x + y = -4
subtract 14x from each side
y = -4 - 14x

Then, plug y into the second equation

-4 - 14x = 3x² - 11x - 4
 then solve from there

Hope this helps :)

Which ordered pairs are solutions to the inequality 2x + y &gt; 8 ? Choose all answers that are correct.
gtnhenbr [62]
Hi again!

2x + y > 8

The correct answer is option D
-------------------------------------------

Honestly I don't think we can solve the equation to find the answer. What we can do is to find the boundary line. (I think you know what that is) After that, shading the appropriate area.

y > -2x + 8

Again, credit to my beautiful graphing calculator. Here is how it looks like.
