Answer:
f^-1(x) = 1/5x + 1/5
Step-by-step explanation:
Switch the x and y values:
y = 5x - 1
x = 5y - 1
Put the equation back into y = form:
x = 5y - 1
x + 1 = 5y
1/5x + 1/5 = y
y = 1/5x + 1/5
f^-1(x) = 1/5x + 1/5
I am bringing 5 dozen cookies to my class. There is 27 students in my class. Only 18 students are here. If there is 9 students absent , how many cookies will each student get ?
So firts you multiply 5 by 12 and that equals 60, than you subtract 27 and 9 and that equals 18, also you will multiply 18 by 60 and that equals 1080, lat but not least you will need to add 9 cookies and then you have 1089, you can divid 1089 by 18 and that equals 60 cookies for each student.
I hope this the right answer and I hoped this helped.
