1.	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.
Answer» 25 – 4x ≤ 16 − 4x ≤ 16 – 25 − 4x ≤ −9 X ≥ 9/4 X ≥ 2.25 (i) The smallest value of x, when x is a real number, is 2.25. (ii) The smallest value of x, when x is an integer, is 3.

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.

Answer»

25 – 4x ≤ 16

− 4x ≤ 16 – 25

− 4x ≤ −9

X ≥ 9/4

X ≥ 2.25

(i) The smallest value of x, when x is a real number, is 2.25.

(ii) The smallest value of x, when x is an integer, is 3.
