Answer:
1
Step-by-step explanation:
9 (x + 9) = 90
(x + 9) = 90/9
x + 9 = 10
x = 10 - 9
x = 1
Answer:
y=11
Step-by-step explanation:
Answer:
816
Step-by-step explanation:
Find total number of people asked by adding all the people.
54 + 56 + 52 + 63 = 225
So, 54 out of 225 people have their favorite snack as brownies.
We need to find out how many it is for 3,400. We can do that by cross multiplying.
54 = x (did it like this so it's better visually)
225 3400
Multiply both sides by 3,400 and divide to get:
x = 816

Ok so you are correct that x is input and y is output
the
you could be talking about a function in general or a kind of function normally used called a one-to-one function which I will assume you are talikning about
one-to-one funciton has that for every input, there is only 1 output, ie, x never repeats with a diffent y
example
(1,2), (2,2) is a function since x didn't repeat
(1,2), (1,3) is not since x repeats with a different y
points given are
(-5,1),(-3,-2), (3,0),(1,1),(2,0),(6,4)(8,-2),(8,7)
we see that the points (8,-2) and (8,7) make it not a function since it is the same input (8) that gives 2 different outputs
professor octavious is wrong since 8 repeats
