Prove that f(x)=x+3/2 and g(x)=2x-3are inverse

Mathematics
1 answer:
goldfiish [28.3K]3 years ago
5 0

Answer:

Proofs

Step-by-step explanation:

f(x) = x +  \frac{3}{2}

y = x +  \frac{3}{2}

x = y +  \frac{3}{2}

x -  \frac{3}{2}  = y

{f}^{ - 1} (x) = x -  \frac{3}{2}

They are not inverse because f^-1(x) = x - 3/2 is not the inverse to g(x) = 2x - 3.

AB = 2x-5 BC = 6x AC = 27
OlgaM077 [116]

Answer:

correct answer is x = 2.75

Step-by-step explanation:

Given;

AB = 2x-5

BC = 6x

AC = 27

Hence,

=> AC = AB + BC

=> 27 = 2x-5 + 6x

=> 27 = 8x-5

=> 27-5 = 8x

=> 22 = 8x

=> 22/8 = x

=> 11/4 = x

or

2.75 = x

Mrrafil [7]
4.72 x 1 = 4.72
8 x X =8x
We need to let the X alone so
4.72 divided 8 = 0.59
1 battery = 0.59
