Answer(s): B

Explanation:

Substitute 6 for m:



The expression can be reduced to

  1. Option A
  2. Option B
  3. Option C
  4. Option D
  5. Option E

Answer(s): D

Explanation:

Factor the numerator and denominator of the fraction:



Which of the following is the vertex of the parabola which is the graph of the equation

  1. (1, 2)
  2. (1, 2)
  3. (1, 2)
  4. (1, 2)
  5. (2, 1)

Answer(s): C

Explanation:

The equation of a parabola with its turning point c units to the left of they-a xis is written as y=(x + c)2. The equation of a parabola with its turning point d units above the x-axis is written as y= x2+d. The vertex of the parabola formed by the equation y = (x+1)2+2is found one unit to the left of they-a x is and two units above the x-axis, at the point (1, 2). Alternatively, test each answer choice by plugging the x value of the choice into the equation and solving for y. Only the coordinates in choice c, (-1, 2, represent a point on the parabola(y = (x+1)2+2, 2=(-1+1)2+2, 2 = 02+2, 2=2, so it is the only point of the choices given that could be the vertex of the parabola.



is equivalent to

  1. Option A
  2. Option B
  3. Option C
  4. Option D
  5. Option E

Answer(s): A

Explanation:

When a base is raised to a fractional exponent, raise the base to the power given by the numerator and take the root given by the denominator. Raise the base, a, to thebth power, since b is the numerator of the exponent. Then, take theth rooth of that:
