If 25 - 4x 16, find : (i) the smallest value of x when x is a real number, (ii) the smallest value of x when x is an integer.

Question

KnowledgeBoat · Accepted Answer

Given, ⇒ 25 - 4x 16 ⇒ -4x 16 - 25 ⇒ -4x -9 Multiplying both sides by -1 we get, ⇒ 4x 9 (As on multiplying by negative no. the sign reverses.) Dividing both sides by 4 we get, ⇒ x ⇒ x 2.25 (i) Given, x 2.25 Hence, smallest value of x when x is a real number is 2.25 (ii) Given, x 2.25 Hence, smallest value of x when x is an integer is 3.
