Answer:
C
Step-by-step explanation:
the size of the steps gives you the number before x
and the -1 , +4 is just what left when x equals zero, so in the two tables we find it in row two
Answer: f(x) = 0.30x + 2.50
This is the same as writing y = 0.30x + 2.50
========================================================
Explanation:
x = number of pounds
y = f(x) = total cost in dollars
1 pound costs $0.30
x pounds cost 0.30x
This is ignoring the entrance fee
Tacking on the entrance fee leads to a total of y = 0.30x + 2.50
------------------
The independent variable is always x and the dependent variable is always y.
The independent variable (number of pounds) determines what the dependent variable (total cost) will be.
Answer:
none
Step-by-step explanation:
"they are the same" translates to ...
x = x +2
0 = 2 . . . . . . subtract x from both sides. — a FALSE statement
There are no values of x or y that make this true.
_____
The two equations describe parallel lines, so they cannot be "the same." There are no points of intersection.

Answer:
Step-by-step explanation:
1. Replace F(x) with y.
2. Interchange x and y in y = 2x + 1: x = 2y + 1
3. Solve this result for y: 2y = x - 1, or y = (x - 1)/2
4. Replace y with:
-1
F (x):
-1 x - 1
F (x) = -----------
