8 0

Answer:

The denominator is all real numbers except 0.

Step-by-step explanation:

In the function f(x) = 1/x, x appears in the denominator. A denominator cannot be zero since division by zero is undefined.

To find what values of x must be excluded from the domain, set the denominator equal to zero, and solve for x.

x = 0

The denominator is all real numbers except 0.

How many ways can Mrs. Sullivan choose two
sveta [45]

In 371 ways Mrs. Sullivan choose two  students from 27 to help put away calculators at  the end of class

Step-by-step explanation:

let us assume that Mrs.Sullivan  wants to choose 2 students from a group of 27 students

So ,in the first choice we have  27 students

In the  second choice we have  26 choices

So Mrs.Sullivan has = 27 × 26 = 702 ways

But  each group repeated twice,in order to avoid that we will divide the answer by 2

so we will write

= 702 ÷ 2 =<u> 351 ways</u>

<u>This method of calculation is called Combination</u>

Mekhanik [1.2K]

Question is Incomplete; Complete question is given below;

Mr. Lin hires a moving company to help transport furniture to his new home. The bill from the moving company is $400. Mr. Lin includes a 15% tip with his payment.

What is Mr. Lin’s total payment, including tip?

Answer:

Mr. Lin made a Total payment of $460 including the Tip.

Step-by-step explanation:

Given:

Total bill = $400

Percentile amount paid in tip = 15%

We need to find the total payment, including tip.

Solution:

First we will find the amount paid in Tip.

amount paid in Tip can be calculated by Percentile amount paid in tip multiplied by Total bill and then divided 100.

amount paid in Tip = \frac{15}{100}\times 400 = \$60

Now we know that;

Total payment made by Mr.Lin is equal to sum of Total bill and amount paid in Tip.

framing in equation form we get;

Total payment made by Mr.Lin = \$400+\$60 =\$460

Hence Mr. Lin made a Total payment of $460 including the Tip.
