sqrt((x))+5x<= 4

(x) + 5 x \leq 4

0 \leq x \leq \frac{16}{25}

Interval Notation

[0, \frac{16}{25}]

Decimal Notation

0 \leq x \leq 0.64

Solution steps

x + 5 x \leq 4

Subtract

5 x

from both sides

x + 5 x - 5 x \leq 4 - 5 x

Simplify

x \leq 4 - 5 x

f (x) \leq g (x)

then

g (x) \geq 0

4 - 5 x \geq 0 : x \leq \frac{4}{5}

x \leq 4 - 5 x : x \leq \frac{16}{25} or x \geq 1
