4 shirts for $18 that is my answer
Answer:

Step-by-step explanation:
In logarithmic functions, if we have an exponent say the
in
, we can "pull it down" from the power and multiply it next to the log.
Let x represent lower level tickets that cost $77
Let y represent upper level tickets that cost $99
Cost equation: 77x + 99y = 247,071
Tickets equation: x + y = 2615
Using the elimination method, multiply the second equation by -77:
77x + 99y = 247,071
-77x - 77y = -201,355
--> 22y = 45,716
--> y = 2,078
Now plug "y" into either equation and solve for "x". I chose the Tickets equation. x + y = 2615 → x = 2615 - y → x = 2615 - 2078 → x = 537
Answer: lower level = 537 tickets, upper level = 2078 tickets.
Answer:
No
Step-by-step explanation:
because it doesn't pass through the origin.
the additive inverse of non complex 9 is -9 .
<u>Step-by-step explanation:</u>
Complex number is said to be the sum of whole numbers and imaginary numbers.The additive inverse of the any number is the changing the sign of the number. That is instead –ve sign is positive and vice versa.
Additive Inverse of Complex Numbers:
Let take the complex numbers
and its inverse be 
Step 1: Now add the Z and Z-1, we get

Step 2: Combine Like term, we get

Step 3: By using zero product property, we can equating as
and 
and 
Thus, the additive inverse of the complex numbers
.
Now, additive inverse of
=
.
Therefore , the additive inverse of non complex 9 is -9 .
