Answer:
f(x) = 4 - x
Step-by-step explanation:
'f(x) = blah-blah' is the same as saying 'y = blah-blah', except it is also telling you that the x-y relationship is a function.
I notice that for each case, x + y = 4, so y = 4 - x
Or in 'function' terminology, f(x) = 4 - x
21d+.23x (d being per day) (x being every mile above 125)
6x + 2 = 2x - 1
Move the variables to one side. I subtract 2x from both sides.
4x + 2 = -1
Subtract 2.
4x = -3
Now divide by 4 on both sides.
x = -3/4 or -0.75
