Answer:

f'(x) = (x + 1)/15

Step-by-step explanation:

f(x) = 15x -1,

Think of the term "f(x)" as a single variable, then solve for the term "x", manipulate the equation like how one would manipulate a literal equation, by inverse operations.

f(x) = 15x - 1

+1 +1

f(x) + 1 = 15x

/15 /15

(f(x) + 1)/15 = x

This means that (denote in the way one would denote an inverse of a function);

f'(x) = (x + 1)/15

{30 POINTS!} HELP! Two communications companies offer calling plans. With Company X, it costs 35¢ to connect and then 5¢ for ea

pav-90 [236]

Answer:

(20 + n)¢

Step-by-step explanation:

With Company X, it costs 35¢ to connect and then 5¢ for each minute.

So, for n minutes of calling the company X charges, C(x) = (35 + 5n)¢

Again, With Company Y, it costs 15¢ to connect and then 4¢ for each minute.

So, for n minutes of calling the company Y charges, C(y) = (15 + 4n)¢.

Therefore, the company Y charges for n minutes of calling less than company X is [(35 + 5n) - (15 + 4n)]¢ = (20 + n)¢ (Answer)

1/4 ÷ 2/3 show,step please

kicyunya [14]

$\frac{1}{4}$ ÷ $\frac{2}{3}$ is the equation

When dividing fractions, you "flip-flop" and multiply

So what that means is that you flip the second fraction and multiply

So $\frac{2}{3}$ is now $\frac{3}{2}$

Now the equation is $\frac{1}{4}$ × $\frac{3}{2}$ which equals $\frac{3}{8}$

Your answer is $\frac{3}{8}$
