Question
A company manufactures cell phone cases. the length of a certain case must be with in of as shown. All cases with lengths outside of this range are removed from the inventory How could you use an absolute value inequality to represent the lengths of all the cases that should be removed ? Explain.
Hint:
|x| is known as the absolute value of x. It is the non-negative value of x irrespective of its sign. The value of absolute value of x is given by
We will construct an equation which models the situation with the help of the concept of absolute value.
The correct answer is: Thus, the equation representing the given situation is 𝑥 − 125 > 0.25
Step by step solution:
Given,
Let the length of the case that should be removed be x
Length of the case = 125 mm
Error that is allowed in making the case = 0.25 mm
We form an equation in terms of length of the case.
The length of the case which is removed is either smaller than (125-0.25) mm or greater than (125+0.25)mm in length
We can write the above lengths as
And
We can rewrite the above equations as
And
X -125 > 0.25
We combine the above two cases to get the following equation.
Thus, the equation representing the given situation is
And
We can rewrite the above equations as
And
We combine the above two cases to get the following equation.
Thus, the equation representing the given situation is
Absolute value of a variable has many uses in mathematics. Geometrically, the absolute value of a number may be considered as its distance from zero regardless of its direction. The symbol |.| is pronounced as ‘modulus’. We read |x| as ‘modulus of x’ or ‘mod x’

A. The cost of 4 tetras is the same as the cost of a rainbow fish.
B. One rainbow fish plus 5 tetras Cost $21.
C. An equation to find the cost r, in dollars of a rainbow fish is 8r + 2(r + 6) = 37
D. Reducing the number of rainbow fish by 1 would result in a total cost of $28.50
E. An equation to find the cost t, in dollars , of a tetra is 8t + 2t + 6 = 37
Let's talk about the cost equation.
A company must determine the cost of producing and selling one of its products to create a cost equation. It must also calculate the overhead costs of production. Typically, the cost equation is the cost of manufacturing and selling one item multiplied by the number of items sold and added to the company's overhead costs.
For example, a company with $300,000 in overhead costs that manufacture and sells products that cost the company $5 each has a cost equation of 300,000 + $5. (5 x number of products sold).
