The numerator of a fraction is 3 less then the denominator. If 1 is added to the numerator, the value of the fraction becomes 3/

andrew11 [14]

The fraction is $\frac{5}{8}$

Step-by-step explanation:

Let,

The denominator of fraction = x

Numerator of fraction = x-3

Fraction = $\frac{x-3}{x}$

According to given statement;

1 is added to the numerator, the value of the fraction becomes 3/4.

$\frac{x-3+1}{x}=\frac{3}{4}\\\\\frac{x-2}{x}=\frac{3}{4}$

Using cross multiplication

$4(x-2)=3*x\\4x-8=3x\\4x-3x=8\\x=8$

Fraction = $\frac{x-3}{x}=\frac{8-3}{8}=\frac{5}{8}$

please help me, im stuck and i do not understand what i need to do, answer the question in the picture please

Answer:

x = - $\frac{1}{4}$

Step-by-step explanation:

To find f(g(x)) substitute x = g(x) into f(x), that is

f(g(x))

= f(x + 1)

= 2(x + 1)² ← expand using FOIL

= 2(x² + 2x + 1) ← distribute

= 2x² + 4x + 2

To find g(f(x)) substitute x = f(x) into g(x), that is

g(f(x))

= g(2x²)

= 2x² + 1

----------------------------------------------------------

Equating gives

2x² + 4x + 2 = 2x² + 1 ( subtract 2x² + 1 from both sides )

4x + 1 = 0 ( subtract 1 from both sides )

4x = - 1 ( divide both sides by 4 )

x = - $\frac{1}{4}$
