Answer:

each box has 52 in it

Step-by-step explanation:

first you subtract 288 from 548  =260

this is the total number of nails minus the total 1 inch nails

then you divide 260 by 5 because he has five boxes of 2 inch names which means that you have to account for the even number of nails in each box

Answer:

There were 52 2-inch nails in each box.

Step-by-step explanation:

Let the number of nails in each 2 inch box be = x

As Tony bought 288 other nails and 5 boxes of 2 inch nails with a total purchase of 548 nails, we get the following equation;

288+5x=548

=> 5x=548-288

=> 5x=260

x = 52

Hence, there were 52 2-inch nails in each box.

Given f(x)=4/5x + 13, find the inverse f-¹(x)<br>Given f(x)= 3/x+10 + 4 find the inverse f-¹(x)​
Elodia [21]
  • f-¹(x) = 69/5y
  • f-¹(x) = 13 + 4y/(y + 10)

<h3>How to determine the inverse </h3>

The steps involved in determining the inverse of a function are;

  • Replace f(x) with y in the equation describing the function
  • Interchange x and y
  • Solve for y
  • Replace y by f-1(x)

If f(x) = 4/5x + 13

y = 4/5y + 13

y = 4 + 65 /5y

f^-1 = 4 + 65 /5y

f^-1(x)= 69/5y

If f(x)= 3/x+10 + 4

y = 3/y + 10 + 4

y = 3 + 4y + 10/(y + 10)

y = 13 + 4y/(y + 10)

f^-1(x) = 13 + 4y/(y + 10)

Thus, the inverse of the functions is 69/5y and 13 + 4y/(y + 10)
