What values from the set {10, 11, 12, 13} that makes the equation 2(× - 5) = 12 true is, , 10, 11, 12 or 13?

olasank [31]

Answer: The value necessary from the set to make the equation true was 11.

Step-by-step explanation:

Process of elimination:

1. 2([10]-5)

= 2(5)

= 10, not 12.

2. 2([11]-5)

= 2(6)

= 12; the answer we need.

We substituted x for 11, and then the equation worked; so therefore the value we needed from the set was 11.

Solve the Quadratic Equation for x

dmitriy555 [2]

Answer:

x = +/- sqrt10 i + 1

Explanation:

Key: +/- is plus-minus

I used complete the square

x^2 - 2x + 11 = 0
x^2 - 2x = -11 -2/2 = (-1)^2 = 1
( x - 1 ) ^2 = -10
x - 1 = +/- sqrt10 i
x = +/- sqrt10 i + 1
