7. g(x) = (4/3)x - 7/3
8. h(x) = (18x + 2)/10
9. f(x) = (2/9)x - 1/9
10. f(x) = (-6x + 2)/5
11. g(x) = (5/8)x - 3/4
12. h(x) = (8x + 9)/8
13. h(x) = (-7/5)x - 1
14. f(x) = (9/8)x + 3/8
15. g(x) = (18x + -36)/30
Are f and g inverses of each other? Give your explanation to support your response.
16. f(x) = (2x + -6)/7
g(x) = (7/2)x + 3
17. f(x) = -(1/5)x + 3/5
g(x) = -5x + 3
18. f(x) = x + 1/2
g(x) = 1x - 1/2
19. f(x) = (63x + 42)/49
g(x) = (7/9)x - 2/5
20. Fahrenheit and Kelvin temperature scales are related by the formula K = 5/9 (F - 32) + 273. Solve this equation for F.

Generally we switch the roles of and to find the inverse.
1. {(18, -3), (-13, -10), (-3, 17), (0, -15)}
the inverse:{(-3, 18), (-10, -13), (17, -3), (-15, 0)}
2. {(5, -11), (-19, -19), (-6, -4), (-3, 8), (-12, 5)}
the inverse:{(-11, 5), (-19, -19), (-4, -6), (8, -3), (5, -12)}
3. {(-9, -8), (-16, 5), (17, 6), (19, 4), (-8, 9), (-10, -10)}
the inverse:{(-8, -9), (6, -16), (6, 17), (4, 19), (9, -8), (-10, -10)}
4. {(8, -5), (-4, -14), (16, 12), (-13, 4), (-17, -2), (3, -13)}
the inverse:{(-5, 8), (-14, -4), (12, 16), (4, -13), (-2, -17), (-13, 3)}
5. {(-14, -9), (-0, 2), (8, -4), (-5, 6), (-7, -4)}
the inverse:{(-9, -14), (2, 0), (-4, 8), (6, -5), (-4, -7)}
6. {(-15, -1), (0, -1), (-6, -1), (-16, 3)}
the inverse: {(-1, -15), (-1, 0), (-1, -6), (3, -16)}

Are and inverses of each other? Give your explanation to support your response.
16. to make sure if and inverses , find inverse of and see if it is equal to
or should be or
...this is and as you can see it is equal to
do same with
....... is equal to
so, and are inverses of each other
I am sure you will be able to do 17,17, and 19 by yourself
