Solve for x:

• x = yb - v

• x = by - v

• x = by + v

Write an equation that models the following situation:
Samantha's hair was known to grow very rapidly. It began at a length of 6 in and grew at a rate of 14% a week.

• y=6(0.14)^x

• y=6(1+14)^x

• y=6(1.14)^x

• y=6(0.86)^x

Convert the point-slope equation y - 12 = 3(x - 9),

to Slope intercept form.

• y = 3x -9

• y = 3 x - 15

• 3x - 12y = -27

• y = 3

Which graph does NOT pass the vertical line test?

• Graph 1

• Graph 2

• Graph 3

• Graph 4

The cost of 5 squash and 2 zucchini is $1.32. Three squash and 1 zucchini cost $0.75. Write a system of equations.

• 5q + 2z = 1.32

  1z = 0.75

• 5q + 2z = 1.32

  3q + 1z = 0.75

• q + z = 1.32

  q + z = 0.75

• 5q + 2z = 0.75

  3q + 1z = 1.32

The length, L , of a rectangle is 8 ft more than 6 times the width,W . The perimeter is 156 ft. Which system of equations best expresses this relationship?

• L+W=156

  L=6W+8

• LW=156

  L=W+6

• L=W+6

  156=2L+2W

• L=6w+8

  156=2L+2W

What is the solution to the systems of equations shown in the graph?

• 1 Solution x=-1/2

• 1 Solution y=-1/2

• Many Solutions

• No Solution

Find the answer using substitution: Please list your answer as a coordinate (x,y)

What are the

roots (x-intercepts) of the function

f(x)= (x - 2)(x + 3)?

• x = - 2 or x = 3

• x = 2 or x = -3

• The are no real roots

• x = 2 or x = 3
