= 11x² + 2

(If you have to solve for x then write the following: )

11x² + 2 = 0

The model represents the equation <br> 4x+ 4 = 12<br> What value of x makes the equation true
myrzilka [38]

Answer:

B

Step-by-step explanation:

All you have to basically do on this one is go backwards.

The beginning equation is 4x+4=12, so to first revesre the adding we are going to use 12, the product, and subtract 4 from it (since that is what was added).

12-4=8

Now you need to reverse the times 4, so to do that just divide instead because that is the invese of multiplication.

8/4=2

Now you have 2, which is the variable, x. To make sure this is right you can just put it into the equation and see if 4x2+4 is 12

Hope this helped!

(-5,3);5×=4y+9 can you help me solve ​
kompoz [17]

Answer:

-25 ≠ 21

Step-by-step explanation:

it looks like the question is asking you to solve 5x=4y+9 when given the ordered pair (-5,3)

you would substitute -5 for x and 3 for y in the equation

5(-5) = 4(3) + 9

-25 = 12 + 9

-25 = 21

the question is asking you to see if the left side is equal to the right side of the equation

-25 is not equal to 21, therefore (-5,3) is not a solution to the equation
