Question

solve the inequality and graph the solution. $\frac{f}{4}+72 < 73$. plot the endpoints. select an endpoint to middle of the segment, ray, or line to delete it.

Explanation:

Step1: Isolate the fraction term

Subtract 72 from both sides of the inequality $\frac{f}{4}+72 < 73$.
$\frac{f}{4}+72 - 72<73 - 72$
$\frac{f}{4}<1$

Step2: Solve for f

Multiply both sides of the inequality by 4.
$4\times\frac{f}{4}<4\times1$
$f < 4$

Answer:

The solution of the inequality is $f < 4$. On the number - line, we have an open - circle at 4 (since the inequality is strict, $f$ cannot equal 4) and the line extends to the left of 4.
