    1.) Graph the solutions q - 7 > 0

    Solving for q:

    q-7+7>0+7

    q>7

    Pleae see the graph in the attaced file

    2.) - x + z > z is only possible if x < 0 (True or false?)

    Solving for x:

    -x+z+x-z>z+x-z

    0>x

    x<0

    Answer: True

    3.) The solution to the inequality 4x > 20 is x > 5. (True or false?)

    Solving for x:

    4x/4>20/4

    x>5

    Answer: True

    4.) Solve the inequality:

    Y

    - - - > 10

    -6

    Solving for y:

    Multiplying the inequality by (-6)

    (-6) [ y / (-6) >10]

    (-6) y / (-6) < (-6) (10)

    y<-60

    Answer: Option C: Y < - 60

    5.) Solve the inequality. 42 < - 6d

    Solving for d

    42-42+6d<-6d-42+6d

    6d<-42

    6d/6<-42/6

    d<-7

    Answer: Second option d < - 7
