Question

Which of the following is not a way to represent the solution of the inequality 2(x − 1) greater than or equal to −12?

a.) x greater than or equal to −5
b.) x less than or equal to −5
c.) −5 less than or greater to x
d.) a number line with a closed circle on negative 5 and shading to the right

Answer 1

2(x - 1) > = -12
2x - 2 > = -12
2x > = -12 + 2
2x > = -10
x > = -10/2
x > = -5 or -5 < = x

wrong solution would be B. x less then or equal to -5....because x is greater then or equal to -5
