4|n+8| = 56 <br><br>please help
Alchen [17]
To solve the absolute value equation you first need to get everything not in the absolute value bars to the other side of the equation.

Step 1) Divide by 4
|n+8| = 14

*Remember: when solving absolute value equations, you make what the expression (n+8) is equal to negative and positive. Not the other way around.

Step 2) Make two equations

n+8 = 14
n+8 = -14

Solve and you'll see that n= 6 and -22

N76 [4]

Answer:

Final Exam score is the response variable.

Step-by-step explanation:

The response variable is the variable of interest. It is what is being tested for given the predictor variables.

Which system is equivalent to 3x squared - 4y squared = 25 over -6x squared -2y squared = 11
TEA [102]
So we are given the following system:
3x^2-4y^2=25\\&#10;-6x^2-2y^2=11\\\text{Multiply the second equation by -2:}\\12x^2+4y^2=-22\\\text{Add to the first equation we get:}\\15x^2=3&#10;\text{ therefore }x=\pm \sqrt{ \frac{1}{5} }
Using the first equation again we get:
3x^2-4y^2=25\\&#10;3x^2=4y^2+25\\&#10;x^2= \frac{1}{3}(4y^2+25)\\x^2= \frac{1}{3}(4 \frac{1}{5} +25)\\= \frac{43}{5}\\x=\pm \sqrt{ \frac{43}{5} }
