Question

If 25 – 4x ≤ 16, find:

(1) the smallest value of x, when x is a real number,

(2) the smallest value of x, when x is an integer.

Solution

25 – 4x ≤ 16

-4x ≤ 16 – 25

-4x ≤ -9

`"x" ≥ 9/4`

x ≥ 2.25

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

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

  Is there an error in this question or solution?
