Answer:

f(x) = 4x - 1

Step-by-step explanation:

The answer to this question is f(x) = 4x - 1 because function notation displays the values of how the input of x yields the output of y. This means that in this form, y is changed to the x input where the substitution of the x in the equation yields the new y.

The ratio of the number of men to the number of women in a sports club is 5:2.

user100 [1]

Let the number of men and the number of women in the beginning be x and y

Now, $\sf \frac{x} {y} =\frac{5}{2} \\\\\sf=2x=5y \\\\\sf=x=\frac{5y}{2}$

Now, In 2nd case,

No. Of men=x-63 and no. Of women =y-12

Now,the ratio becomes $\frac{x-63}{y-12}=\frac{7}{4} \\\\\sf=4(x-63)=7(y-12) \\\\\sf=4x-252=7y-84 \\\\\sfPutting,\:x=\frac{5y}{2}\:in\: 4x-252=7y-84\:we\: get, \\\\\sf10y-252=7y-84 \\\\\sf=10y-7y=252-84 \\\\\sf=3y=168 \\\\\sf=y=56 \\\\\sf=\boxed{Y=56}$

Now,we have, 2x=5y

Putting the value of Y=56 in 2x=5y,we get,

$\sf 2x=5\:x\:56 \\\\\sfx=\frac{5\:x\:56}{2} \\\\\sfx=\frac{5\:x\: \cancel{56}\:\:28}{ \cancel{2}} \\\\\sf=x=5\: x\: 28 \\\\\sfx=140 \\\\\sf\boxed{x=140}$

Hence, the number of men was 140 and the no. of women was 56
