Solving Absolute Value Equations
For nitrogen to be a liquid, its temperature must be within 12.78 °F of -333.22 °F.
The equation |x + 333.22 | = 12.78 can be used to find x, which represents the
maximum and minimum temperatures at which nitrogen is a liquid.
? is the maximum temperature at which nitrogen is a liquid.
? is the minimum temperature at which nitrogen is a liquid. - ANS - -320.44 is the
maximum temperature at which nitrogen is a liquid.
-346 is the minimum temperature at which nitrogen is a liquid.
\For nitrogen to be a liquid, its temperature must be within 12.78 °F of -333.22 °F.
Which equation can be used to find the maximum and minimum temperatures at
which nitrogen is a liquid, x?
The equation that can be used to find the maximum and minimum temperatures is
|x + ? | = .? - ANS - |x + 333.22 | =.12.78
\Jamaal is allowed to walk no farther than three blocks in either direction from his
house. If his house is located on the 57th block of the town, which absolute value
equation can be used to determine the farthest block to which Jamaal is allowed
to walk? - ANS - D: |x - 57| = 3
\Josefina started to solve for x in the equation
3.5 = 1.9 - 0.8|2x - 0.6| using the steps below:
3.5 = 1.9 - 0.8|2x - 0.6|
1.6 = -0.8|2x - 0.6|
-2 = |2x - 0.6|
Why did Josefina stop at Step 3? - ANS - Absolute values cannot equal a negative
number. This equation has no solution.
\Max rides his scooter toward Kim and then passes her at a constant speed. His
distance in feet, d, from Kim t seconds after he started riding his scooter is given
by d = |150 - 9t|.
1: What does the 150 in the equation represent?
2: What does the 9 in the equation represent? - ANS - 1: Max's starting distance
from Kim
2: Max's constant speed
