Okay so, f(x) is another way of writing y.
If the problem were to give you an x value you would put it in the x spot.
For example:
f(x) = 1/2x - 7
is the same thing as y = 1/2x - 7
If the problem were to say: "Solve for y, if x = 2" your problem would look like this
f(2) = 1/2(2) + 7
Now, multiply 1/2 by 2, and you get 1. Now the equation is:
f(2) = 1 + 7
So add 1 and 7 = 8
so that would be f(2) = 8
And your final answer would be y = 8

I would need a graph chart to do this, sorry :/
Answer:
183.3333
Step-by-step explanation:
Let the number be X
Therefore
0.6X=110
X=110/0.6
X=183.3333
Answer:
-9,-21
Step-by-step explanation:
let the numbers be x and y and x>y
x-y=12
y=2x-3
x-(2x-3)=12
x-2x+3=12
-x=12-3
-x=9
x=-9
y=2(-9)-3=-18-3=-21
