Question

Which of the following is the solution to the inequality -2x-4 ≤ 11

Answer 1

Isolate the variable by dividing each side by factors that don't contain the variable.

Inequality Form:

x ≥ −15/2

Interval Notation:

[−15/2, ∞)

Answer 2

`x\geq -(15)/(2)`

Explanation:

add 4 on both sides

leaves you with 15 on the right side

you then divide by negative 2

since you divide by a negative you have to switch the sign
