The graph and inverse of a function are reflections of each other along the line y = x.
A relation made up of ordered pairs (x, y) has as its inverse the set of all ordered pairs (y, x).
When a point is mirrored over the line y = x, the x- and y-coordinates swap places. Similarly, when a point is mirrored over the line y = -x, the x- and y-coordinates swap places and become negated.
Therefore,
The point (x, y)'s reflection over the line y = x is (y, x).
The point (x, y)'s reflection over the line y = - x is (-y, -x).
Thus, the graph and inverse of a function are reflections of each other along the line y = x.

Answer:
ax+16=b−3x
Step-by-step explanation:
Step-by-step explanation:
7 1/5 × 49 7/5 = 49
convert mixed numbers into improper fractions (whole number × denominator + numerator)
7 × 5 + 1 = 36
49 × 5 + 7 = 252
36/5 × 252/5 = 49
All fractions must have a common denominator
49 × 5 = 245
36/5 × 252/5 = 245/5
Add numerators
36 + 252 = 288
288/5 = 245/5
57 3/5 = 49
These do not equal each other according to my calculations. Is the problem written correctly? Or did I misinterpret a given number?
(josue) 16.8/7 = $2.4 per lb
(ricardo) 12.75/5 = $2.55 per lb
ricardo is incorrect because if you solve for the price per pound ( price/amount ), josue paid $2.40 for each pound of pretzels while ricardo paid $2.55 per pound. ricardo ended up paying more.
