I need to know how to find x

Mathematics
1 answer:
enyata [817]2 years ago
5 0

Answer:

x = \frac{20}{3}

Step-by-step explanation:

ΔABC and ΔEDC are similar triangles ( AA ), hence the ratios of corresponding sides are equal, that is

\frac{AB}{ED} = \frac{BC}{DC}, substitute values

\frac{x}{4} = \frac{5}{3} ( cross- multiply )

3x = 20 ( divide both sides by 3 )

x = \frac{20}{3}

Determine whether f(x)=5x+1/x and g(x)= x/5x+1 are inverse functions. Explain how you know.
vladimir1956 [14]
A property of inverse functions is that if f(x) = a, g(a) = x

F(x) = (5x+1)/x
G(x) = x/(5x+1)

Plug in x = 3.
F(3) = 16/3
G(16/3) = 16/83. Since it doesn’t equal 3, it’s not an inverse function
