Question

If $4x\le -3$, then $4x\times (-3)$$(-3)\times (-3)$.
If $-3x>4$, then $(-3x)\times \left(4\right)$$4\times 4$.

• A. $<$
• B. $>$
• C. $\le$
• D. $\ge$

Answer 1

Answer: (B), (D)

$\ge$

Given algebraic inequality $4x\le -3$
On multiplying both sides of the algebraic inequality by $-3$
We get: $\left(4x\right)\times (-3)\ge (-3)\times (-3)$

Next, given algebraic inequality $-3x>4$
On multiplying both sides of the algebraic inequality by $4$
We get: $(-3x)\times 4>4\times 4$
