What is the range of f(x) = 3^x + 9? 1. {y | y < 9}
2. {y | y > 9}
3. {y | y > 3}
4. {y | y < 3}

S-7< 3 i need answering this problem someone asap answer

Factor the monomial completely 42a3b3

Follow these steps using the algebra tiles to solve the equation −5x + (−2) = −2x + 4. 1. add 5 positive x-tiles to both sides and create zero pairs. 2. add 4 negative unit tiles to both sides and create zero pairs. 3. divide the unit tiles evenly among the x-tiles. x =
