A refrigerator should be set at 38*f with an allowance for 2*. 1.) Write an equation to find the maximum temperatures at which the refrigerator should be set. 2.) Solve the equation to find the maximum and minimum temperatures at which the refrigerator should be set.

1) For this case we can use the absolute value and we can write the limit with this expression:

Where T represent the temperature for the refrigerator in F.

2) If we solve for T we have this:

We can add 38 in all the sides of the inequality

And finally we got:

So then the refrigerator can work between 36 F and 40 F for this case.

Step-by-step explanation:

For this case we know that the refrigerator hould be set at 38 F, and the allowance or the variation is 2F.

Part 1

For this case we can use the absolute value and we can write the limit with this expression:

Where T represent the temperature for the refrigerator in F.

Part 2

If we solve for T we have this:

We can add 38 in all the sides of the inequality

And finally we got:

So then the refrigerator can work between 36 F and 40 F for this case.

26?

step-by-step explanation:

example 2 – simplify: step 1: completely factor both the numerators and denominators of all fractions. step 2: change the division sign to a multiplication sign and flip (or reciprocate) the fraction after the division sign; essential you need to multiply by the reciprocal. step 3 : cancel or reduce the fractions.
