Simplify (5x2 + 3x + 4) + (2x2 − 6x + 3). 7x2 + 9x + 7 7x2 + 3x + 7 7x2 − 3x + 1 7x2 − 3x + 7

What is the multiple zero and multiplicity of f(x) = (x ? 3)(x ? 3)(x + 5)? multiple zero is 3; multiplicity is 2 multiple zero is 5; multiplicity is 1 multiple zero is ? 5; multiplicity is 1 multiple zero is ? 3; multiplicity is 2

Idon’t understand! use slope intercept form to solve: through: (2,5) slope= undefined

The graph shows the decibel measure for sounds depending on how many times as intense they are as the threshold of sound. noise in a quiet room is 500 times as intense as the threshold of sound. what is the decibel measurement for the quiet room? 20 decibels28 decibels200 decibels280 decibels
