If 25 – 4x ≤ 16, find:
- the smallest value of x, when x is a real number.
- the smallest value of x, when x is an integer.
उत्तर
25 – 4x ≤ 16
– 4x ≤ 16 – 25
– 4x ≤ – 9
`x ≥ 9/4`
x ≥ 2.25
- The smallest value of x, when x is a real number, is 2.25.
- The smallest value of x, when x is an integer, is 3.
