Question

solve for x and graph the solution on the number line below.
4x ≥ 16
answer attempt 1 out of 2
< > ≤ ≥ or
inequality notation:
number line:
-12 -10 -8 -6 -4 -2 0 2 4 6 8 10 12
click and drag to plot line.
submit answer

Explanation:

Step1: Isolate x

Divide both sides by 4.
$4x\geq16$ becomes $x\geq\frac{16}{4}$

Step2: Simplify the right - hand side

$\frac{16}{4}=4$, so $x\geq4$

Answer:

Inequality Notation: $x\geq4$
Number Line: Plot a closed circle at 4 (because of $\geq$) and draw a line to the right.
