Eamon wants to buy a new baseball glove that costs $50. he has $14 and earns $6 per hour cleaning yards. How many hours must he
konstantin123 [22]

Answer:

The answer is that he would have to work 6 hours to have enough money to buy the glove.

Step-by-step explanation:

1: Find the amount he needs to earn by subtracting $14 from $50: 50 - 14 = 36. So he needs to earn $36.00.

2: Since you have to find the amount of hours, you can divide $6 from $36 to get the amount of hours he needs to work: 36 / 6 = 6. Eamon only gets $6.00 per hour so he would have to work 6 hours to get the $36.00.

Which function is f(x) equal to f^-1(x)?
Morgarella [4.7K]

Answer:

c. f(x) x+1/x-1

Step-by-step explanation:

To answer this question, we need to check each answer one by one until we find the right one.  

y = (x+6)/(x-6)  

switch x and y  

x = (y+6)/(y-6)  

solve for y  

x(y-6) = y+6  

xy - 6x = y+6  

y(x-1) = 6x+6  

y = (6x+6) /(x-1) = 6(x+1)/(x-1)  

f^-1(x) = 6(x+1)/(x-1)  

y = (x+2)/(x-2)  

switch x and y  

x = (y+2)/(y-2)  

solve for y  

x(y-2) = y+2  

xy -2x = y+2  

y(x-1) = 2x+2  

y = (2x+2)/(x-1)  

f^-1(x) = 2(x+1)/(x-1)  

y = (x+1)/(x-1) ------ correct one  

switch x and y  

x = (y+1)/(y-1)  

solve for y  

x(y-1) = y+1  

xy - x = y+1  

y(x-1) = x+1  

y = (x+1)/(x-1)  

f^-1(x) = (x+1)/(x-1)  

f(x) = f^-1(x)
