4-9y^2>= 0

Solution

4 - 9 y^{2} \geq 0

Solution

- \frac{2}{3} \leq y \leq \frac{2}{3}

+2

Interval Notation

[- \frac{2}{3}, \frac{2}{3}]

Decimal Notation

- 0.66666 \dots \leq y \leq 0.66666 \dots

Solution steps

4 - 9 y^{2} \geq 0

Move

4

to the right side

- 9 y^{2} \geq - 4

Multiply both sides by

- 1

9 y^{2} \leq 4

Divide both sides by

9

y^{2} \leq \frac{4}{9}

For

u^{n} \leq a

, if

n

is even then

- \frac{4}{9} \leq y \leq \frac{4}{9}

\frac{4}{9} = \frac{2}{3}

- \frac{2}{3} \leq y \leq \frac{2}{3}
