For f(x) = 5x + 1
drek231 [11]

Answer:

A. f(7) = 5(7) + 1\\\\f(7) = 36

B. f^{-1}(x) = \frac{x - 1}{5}

C. f^{-1}(7) =\frac{6}{5}

D. f(\frac{6}{5}) = 7

Step-by-step explanation:

A. To solve the first part of the problem we must replace x = 7 in the function f(x) = 5x + 1

So:

f(7) = 5(7) + 1\\\\f(7) = 36

B. In part B we must find the inverse function of f(x) = 5x + 1

To find the inverse function do y = f(x)

y = 5x +1

Now clear the variable x.

\frac{y - 1}{5} = x

Replace x with y.

y = \frac{x - 1}{5}

Finally

f^{-1}(x) = \frac{x - 1}{5}

C. Now we take the inverse function found above and replace x = 7

f^{-1}(7) = \frac{7 - 1}{5}\\\\f(7) = \frac{6}{5}

D. Now we substitute x = f(f^{-1}(7)) in the original function.

x = f( f^{-1}(7))\\\\f^{-1}(7) = \frac{6}{5}\\\\ x= f(\frac{6}{5} )\\\\f(\frac{6}{5}) = 5(\frac{6}{5}) + 1\\\\f(\frac{6}{5}) = 7

Please do all problems with work on paper thank you​
damaskus [11]

a. \frac{11}{12}

b. \frac{39}{20}

c. \frac{20}{21}

Step-by-step explanation:

Step 1; First, we convert the given fractions into improper ones. To do this, we multiply the whole number with the denominator of the fraction and add with it the same fraction's numerator whereas the denominator remains unchanged. To convert the fraction

3\frac{1}{4} = (3 × 4) + 1 / 4 = \frac{13}{4},

2\frac{1}{3} = (2 × 3) + 1 / 3 = \frac{7}{3},

6\frac{1}{5} = (6 × 5) + 1 / 5 = \frac{31}{5},

4\frac{1}{4} = (4 × 4) + 1 / 4 = \frac{17}{4},

5\frac{2}{7} = (5 × 7) + 2 / 7 = \frac{37}{7},

4\frac{1}{3} = (4 × 3) + 1 / 3 = \frac{13}{3}.

Step 2; Now we subtract, using LCM to arrive at the answer

3\frac{1}{4} - 2\frac{1}{3} = \frac{13}{4} - \frac{7}{3} = \frac{39-28}{12} = \frac{11}{12},

6\frac{1}{5} - 4\frac{1}{4} = \frac{31}{5} - \frac{17}{4} = \frac{124-85}{20} = \frac{39}{20},

5\frac{2}{7} - 4\frac{1}{3} = \frac{37}{7} - \frac{13}{3} = \frac{111-91}{21} = \frac{20}{21}.
