Answer:
x is less than or equal to 29
Step-by-step explanation:
-49 <_ 9 - 2x
isolate the variable.
-49 - 9 <_ 9 - 2x - 9
-58 <_-2x
-58/-2 <_-2x/-2
When dividing or multiplying by negatives, flip the sign.
-58/-2 <_-2x/-2
29 >_ x
x <_ 29
x is less than or equal to 29
Using an absolute value equation, it is found that:
- The minimum temperature of the aquarium is of 72 ºF.
- The maximum temperature of the aquarium is of 80 ºF.
<h3>What is the absolute value function?</h3>
The absolute value function is defined by:
It measures the <u>distance of a point x to the origin</u> of x = 0, which means that both -2 and 2 are 2 units from 0, hence |-2| = |2| = 2.
The difference between the temperature x and 76 ºF is of 4 ºF, hence the equation is given by:
|x - 76| = 4.
The solutions are found as follows:
Hence:
- The minimum temperature of the aquarium is of 72 ºF.
- The maximum temperature of the aquarium is of 80 ºF.
