Answer:
16n + 18
Step-by-step explanation:
-5n + 3(6 + 7n)
Distributing the 3 over the parenthesis:-
= -5n + 3*6 + 3*7n
= -5n + 18 + 21n
= 16n + 18
Answer:
A, B, D, and E
Step-by-step explanation:
recall that the inverse functions verify the identity rule that one function applied on the other will render the identity "x". It is like launching a function from a value x, and then taking the trip back to the value that originated it.
Such also implies that the domain where you started becomes the Range of the function that makes the trip back. And of course, its reciprocal: The Range of the starting function becomes the Domain of the function that gets back.
Therefore, andswers A, B, D and E are correct answers
E.g.
4
4/4=1
but
4/8=0 remainder 4
--------------------------------
12
12/4=3
but
12/8=1 remainder 4
Answer:
Andy gets 7 questions wrong.
Step-by-step explanation:
Let A, B, C and D be the number of questions answered wrong by Andy, Beth, Charlie, and Daniel, respectively.
Andy and Beth together get the same number of questions wrong as Charlie and Daniel together:
Andy and Daniel together get four more questions wrong than Beth and Charlie do together:
Charlie gets five questions wrong:
Solving the linear system:
Andy gets 7 questions wrong.
Answer: Cost of tickets for adults = $22
Cost of tickets for children = $15
Total number of tickets sold = 732
Total receipts = $12,912
Let x be number of adult ticket's sold and y be the number of child ticket's sold.
Therefore, we have:
--------------- equation 1
Also, we have:
Now, let's substitute the value of x:
Now, let's substitute the value of y=456 in equation 1, we have:
Therefore, the number of child ticket's sold is 456 and number of adult ticket's sold is 276
