Question

Solve the inequality 4i−4(i+2)≥6(8i−8) and write the solution in interval notation

Answer 1

Answer:

$(-\infty,\frac{25}{24}]$

Step-by-step explanation:

Assuming $i$ is a variable:

$4i-4(i+2)\geq6(8i-8)\\\\4i-4i+2\geq48i-48\\\\2\geq48i-48\\\\50\geq48i\\\\\frac{50}{48}\geq i\\ \\\frac{25}{24}\geq i\\ \\i\leq\frac{25}{24}\\ \\(-\infty,\frac{25}{24}]$
