State, True or False : (i) x<−y ⇒ −x>y (ii) −5x≥15 ⇒ x≤�

1.	State, True or False : (i) x<−y ⇒ −x>y (ii) −5x≥15 ⇒ x≤−3 (iii) 2x≤−7 ⇒ 2x−4≥−7−4 (iv) 7>5 ⇒ 17<15
Answer» State, True or False : (i) $x < - y \Rightarrow - x > y$ (ii) $- 5 x \geq 15 \Rightarrow x \leq - 3$ (iii) $2 x \leq - 7 \Rightarrow \frac{2 x}{- 4} \geq \frac{- 7}{- 4}$ (iv) $7 > 5 \Rightarrow \frac{1}{7} < \frac{1}{5}$

State, True or False : (i) x<−y ⇒ −x>y (ii) −5x≥15 ⇒ x≤−3 (iii) 2x≤−7 ⇒ 2x−4≥−7−4 (iv) 7>5 ⇒ 17<15

Answer»

State, True or False :

(i) $x < - y \Rightarrow - x > y$

(ii) $- 5 x \geq 15 \Rightarrow x \leq - 3$

(iii) $2 x \leq - 7 \Rightarrow \frac{2 x}{- 4} \geq \frac{- 7}{- 4}$

(iv) $7 > 5 \Rightarrow \frac{1}{7} < \frac{1}{5}$
