Answer:

Those system of equations are called the system of linear equations with multiple variables.

Step-by-step explanation:

Here it is given a system equations as  

x = 5 ....... (1)

y = 6 ........... (2) and  

- x - y + z = 0 ........ (3)

Those systems of equations are called the system of linear equations with multiple variables.

Those are linear equations as the maximum power of the variables is 1.

We can solve those equations with simple algebra.

Here, x = 5, y = 6 and z = x + y = 5 + 6 = 11 (Answer)

elect the correct answer. graph A graph B graph C graph D A credit card company uses these rules to calculate the minimum amount
laila [671]

The graph that correctly shows the minimum amount due for a credit amount (x)  is graph B.

<h3>How to determine the graph with the minimum amount due?</h3>

First of all, we would assign a variable to the different amount of money as follows:

  • Let x be the credit amount.
  • Let y be the minimum amount due.

Translating the word problem into an algebraic expression, we have;

For a bill of less than $100, the entire amount is due:

0 ≤ x < $100, therefore, y = x

For a bill of at least $100 but less than $500, the minimum due is $100: $100 ≤ x < $500, therefore, y = 100

For a bill of at least $500 but less than $1,000, the minimum due is $300:

$500 ≤ x < $1000, therefore, y = $300

For a bill of $1,000 or more, the minimum due is $500:

Since the credit limit is equal to $2000, we have $1000 ≤ x < $2000 and y = $500

In conclusion, the graph that correctly shows the minimum amount due for a credit amount (x)  is graph B.
