Hi There!

Your answer will be 405 1/2

To get this answer you must divide 811/2. If i'm correct when you get your answer the top will be the mixed number. The side number will be the denominator and the bottom number will be the numerator.

Solve x2 + 12x = –11 by completing the square. Which is the solution set of the equation?

Ann [662]

If you would like to solve the equation x^2 + 12 * x = -11, you can calculate this using the following steps:

x^2 + 12 * x = -11
x^2 + 12 * x + 11 = 0
(x + 1) * (x + 11) = 0
1. x = - 1
2. x = - 11

The correct result would be x = - 1, or x = - 11.

Please answer this it’s very hard for me

Answer:

C, D, E, F

Step-by-step explanation:

Remember y=mxb?

m is slope and b is y-intercept

so y=2/7x-9

Remember that slope is RISE/RUN so for every 2 squares that you go up, you go 7 squares to the right.

Also remember that since your graph is going thru your Cartiesian Plane in quadrent 4, your y value in your ordered pairs will most probably be a negative.
