Solve the inequality. Graph the solution on a number line. 7 ≥ t/-2

Elodia [21]

$t\geq -14$

The graph is shown in the figure attached.

Step-by-step explanation:

We need to solve the inequality $7\geq \frac{t}{-2}$ and graph the solution.

Solving the inequality: $7\geq \frac{t}{-2}$

Switch sides and reverse the inequality:

$\frac{t}{-2}\leq 7$

Multiplying both sides by -2 and reverse the inequality

$-2\frac{t}{-2}\geq 7*-2$

$t\geq -14$

The graph is shown in the figure attached.
