ANSWER
First choice
EXPLANATION
The graph of f(x) and
are symmetric about the line y=x.
This means that the graph of
is the reflection of f(x) in the line y=x.
This explains why the composition of a function and its inverse yields x, as the result.
The first choice is correct.
Answer:
see explanation
Step-by-step explanation:
Since it is a balance then both sides are the same, that is equal.
The 4 weights represented by circles can be written as 4w, then
4w = 25 ← equation representing the situation
Divide both sides by 4 to find w
w = 25 ÷ 4 = 6.25 ← the weight of 1 circle

Step-by-step explanation:
$19.50
-$15.50=
$4.00
1slice of pizza and 1soda is $4
so 2slices of pizza and 2 sodas is $8
$15.50-$8=$7.50
Now you have 3 slices of pizza left
$7.50/3slices=$2.50
1slice of pizza is $2.50
