Question

solve the inequality and graph the solution.
51 ≤ t + 55
to draw a ray, plot an endpoint and select an arrow. select an endpoint to change it from closed to open. select the middle of the ray to delete it.

Explanation:

Step1: Isolate the variable t.

Subtract 55 from both sides of the inequality $51\leq t + 55$.
$51-55\leq t+55 - 55$

Step2: Simplify the expressions.

$-4\leq t$ or $t\geq - 4$

Answer:

The solution of the inequality is $t\geq - 4$. To graph it, plot a closed - circle at $t=-4$ (because the inequality is $\geq$) and draw a ray to the right.
