The Least Common Multiple of 5, 6, 7, and 9 goes into 5, 6, 7, and 9. The Least Common Multiple of 5, 6, 7, and 9 is 630. If you multiply that by 2, 3, 4, and so on, you get a never-ending set of numbers that go into 5, 6, 7, and 9.
Answer:
f^-1(x) = x +6
Step-by-step explanation:
To find the inverse of the function
y = f(x)
solve the equation
x = f(y)
for y.
Here, you want ...
x = f(y)
x = (y -6)
x +6 = y . . . . . . add 6 to both sides

I just took the test, the answer is: Fiona's meals are less expensive. :)
For both GCF and LCM you find something in common.There is nothing else similar but only differences
18/6=3,3•(-3)=-9,28+(-9)=19
19 is your answer
