Answer:
-12
Explanation:
We are given information to solve for 2 variables x and y. To solve this I substituted 3x for y in the equation 5x - 4y = 21
So substituting gets us 5x - 4(3x) = 21
and we can solve the equation for x
5x - 12x = 21
-7x = 21
x = -3
Now that we have found x, we can find y simply by putting it in the equation y = 3x
y = 3(-3) = -9
Once we have both variables, we can find the answer to x + y
-3 + -9 = -3 - 9 = -12
So the answer to the question
x + y = -12
1. Ten school children are asked to stand in a line to wait for ice cream cones.
A "line" in this case is a permutation because the order makes a difference. If
Raquel is first in line, that's different than being second or last. How many
different lines are possible for these 10 children?
Answer:
There are 3628800 possible number of arrangements
Explanation:
Given
Number of children = 10
Required
Possible number of arrangements
From the question, we understand that the order of arrangement matters;
So; to solve this, we make use of the following formula
[tex]n! = n * (n-1) * (n-2) * ..... * 3 * 2 * 1[/tex]
In this case, n = 10
[tex]10! = 10 * 9 * 8 * 7 * 6 * 5 * 4 * 3 * 2 * 1[/tex]
[tex]10! = 3628800[/tex]
Hence, there are 3628800 possible number of arrangements
Identify whether each example is a job change, or a career change. Taryn is a Salesperson who leaves a job at a grocery store and takes a job at a department store: Monika is a High School Principal who takes a new job at a different high school: Justina is a Carpenter who takes a job as an Electrician: Odell is a Flight Attendant who undergoes training and becomes an Airline Pilot: Archie is a Registered Nurse who leaves his job at a hospital and goes to work at a nursing home: Frederick is a Bank Teller who takes a job as a Cashier:
Answer:
Taryn is a Salesperson who leaves a job at a grocery store and takes a job at a department store: Job change.
Monika is a High School Principal who takes a new job at a different high school: Job change.
Justina is a Carpenter who takes a job as an Electrician: Career change.
Odell is a Flight Attendant who undergoes training and becomes an Airline Pilot: Career change.
Archie is a Registered Nurse who leaves his job at a hospital and goes to work at a nursing home: Job change.
Frederick is a Bank Teller who takes a job as a Cashier: Job change.
Explanation:
A job change is when there is a change in the job/ place of work but the person still retains or does the same work, but just in a new environment. Whereas a career change is when the person changes his field of expertise or interest from one field to another, thereby making a complete overhaul of things. This may not necessarily involve a change in the workplace.
In the case of Taryn, Monika, Archie, and Frederick, their jobs remain the same even when they change their workplace. Taryn change from a grocery store to a department store, Monika from one high school to another, Archie from a job as a registered nurse in a hospital to a nursing home while Frederick changes from a Bank Teller to a cashier.
Whereas, Justina's case of changing from a carpenter to an electrician and Odell's job as an Airline Pilot from a Flight Attendant are examples of career changes.
