Question

Help please!!!!!!!!!! ​

Answer 1

`\large\boxed{x\geq-(4)/(3);\ y\geq5}`

Explanation:

We know:

`√(a)=b\ for\ a\geq0\ adn\ b\geq0`

We have

`y=2√(3x+4)+5`

Therefore

`3x+4\geq0` subtract 4 from both sides

`3x\geq-4` divide both sides by 3

`x\geq-(4)/(3)`

`√(3x+4)\geq0` multiply both sides by 2

`2√(3x+4)\geq0` add 5 to both sides

`2√(3x+4)+5\geq5\to y\geq5`
