Asa saves dimes and quarters so that he will have exact change for he bus. He dabs and then dumps the container that he has been

koban [17]

Asa has 15 dimes and 32 quarters.

Step-by-step explanation:

Given,

Total coins = 47

Worth of coins = $9.50 = 9.50*100 = 950 cents

1 dime = 10 cents

1 quarter = 25 cents

Let,

Number of dimes = x

Number of quarters = y

According to given statement;

x+y=47 Eqn 1

10x+25y=950 Eqn 2

Multiplying Eqn 1 by 10

$10(x+y=47)\\10x+10y=470\ \ \ Eqn\ 3$

Subtracting Eqn 3 from Eqn 2

$(10x+25y)-(10x+10y)=950-470\\10x+25y-10x-10y=480\\15y=480$

Dividing both sides by 15

$\frac{15y}{15}=\frac{480}{15}\\y=32$

Putting y=32 in Eqn 1

$x+32=47\\x=47-32\\x=15$

Asa has 15 dimes and 32 quarters.

Need help with this function problem

kotykmax [81]

Answer:

see attached

Step-by-step explanation:

To find the inverse function, solve ...

x = f(y)

x = (y^7)/7 -4 . . . . . . . use the definition of f(x)

x +4 = (y^7)/7 . . . . . . add 4

7(x +4) = y^7 . . . . . . multiply by 7

(7(x +4))^(1/7) = y . . take the 7th root

The inverse function is the one shown in the attachment.
