Write an inequality for Graph 3.

• x ≤ -2 AND x > 5
• x ≤ -2 OR x > 5
• x ≥ -2 OR x < 5
• -2 ≤ x < 5

• n > 6 and n < -14

• n > -1 or n < -7

• n > -7 and n < -1

• no solution

What is the reason that absolute value is always written as a positive?

• Absolute value is talking about numbers so it must be positive.
• Absolute value does not always have to be positive.
• Absolute value is like a clock it has only positive numbers.
• Absolute value is talking about distance, distance is always measured by positive numbers.

Solve |x – 12| - 3 = 11.

• -2, -26
• -2, 26
• 3, 25
• 4, -7

solve for x

• 25/4

• 12/7

• -5/2

• -3/4

solve for m

• -15
• 15
• 30
• -30

−6 < 2t − 5 < 3

• −0.5 < t < 4

• 0.5 < t < −1

• −11/2 < t < 2

• 11/2 < t < −2

Solve for x:

ax - b = cx + d

• x = (a-c)/(b+d)

• x = (b+d)/(a-c)

• x = (b+d)/(a+c)

• x = (a+c)/(b-d)

• (2.5+h)f
• g=1
• f(5+h)/2
• (5f+h) / 2

Which relation is NOT a function?

• {(1,-5), (3,1), (-5,4), (4,-2)}
• {(2,7), (3,7), (4,7), (5,8)}
• {(1,-5), (-1,6), (1,5), (6,-3)}
• {(3,-2), (5,-6), (7,7), (8,8)}
