1. x = cost of one adult ticket
y= cost of one child ticket
2x+3y=31.60
x+2y=18.60 l multiply by -2
2x+3y=31.60
-2x-6y=-37.2
-3y=-5.6
y=1.87
2x+3(1.87)=31.60
2x+5.6=31.60
2x=31.60-5.6
2x=26
x=26/2
x=13
Answer: The adult ticket is $13 and the child ticket is $1.87
we have
Find the inverse of f(x)
Let
Exchanges the variables x for y and y for x
isolate the variable y
Let
-----> inverse function
Hence
In the inverse function the denominator can not be zero, therefore the value of m can not be equal zero
<u>the answer is the option</u>
Here is the answer
RQ= 52/2
RQ=26
