2. A zero of an expression is a value of the input variable that results in the expression having a value of zero (catchy and appropriate name). Is x=3 a zero of the quadratic expression shown below? Justify your
yes/no answer.
4x - 8x-12

A, b, c, and d have the coordinates (-8, 1), (-2, 4), (-3, -1), and (-6, 5), respectively. which sentence about the points is true? a. a, b, c, and d lie on the same line. b. and are perpendicular lines. c. and are parallel lines. d. and are intersecting lines but are not perpendicular. e. and are parallel lines.

If (x-2) 2= 49, then x could be a. -9 b. -7 c.- 2 d. 5 e.9

20 solve 2(4 x + 3) < 5 x + 21. a) { x | x < 9} b) { x | x > -5} c) { x | x > -9} d) { x | x < 5}
