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

The equation X squared plus Y squared minus 2X plus 7Y +1 equals zero can be written as which of the following equations
ad-work [718]

For this case we must write in algebraic symbology the expression described above:

We have an equation, then:

  • x squared plus y squared: x ^ 2 + y ^ 2
  • minus 2x plus 7y plus 1: -2x + 7y + 1
  • equals zero: = 0

We construct the equation:

x ^ 2 + y ^ 2-2x + 7y + 1 = 0

Answer:

x ^ 2 + y ^ 2-2x + 7y + 1 = 0
