Solve for x −9x+5≤17 OR 13x+25≤−1
arsen [322]

Answer:

(-∞ 2] ∪ [-4/3 ∞ )

Step-by-step explanation:

Given compound inequality,

-9x+5\leq 17\text{ or }13x+25\leq -1

-9x\leq 12\text{ or }13x\leq -26  ( Subtraction property of inequality )

-x\leq \frac{12}{9}\text{ or }x\leq -\frac{26}{13}   ( Division property of inequality )

-x\leq \frac{4}{3}\text{ or }x\leq -2

x\geq -\frac{4}{3}\text{ or }x\leq -2   ( a < b ⇒ - a > - b )

Hence, the solution of the given inequality is,

(-∞ -2] ∪ [-4/3 ∞ )
