Answer:

64 nickels and 24 dimes

Step-by-step explanation:

Let there be x nickels and y dimes

The number of nickels is 8 less than 3 times the dimes

i.e. x = 3y-8

Value of the coins = 5x+10y

= 560 cents (given)

Substitute x value in the second equation

5(3y-8)+10y = 560\\25y = 600\\y =24\\

Substitute in

x = 3y-8\\=64

There are 64 nickels and 24 dimes.

Given the piecewise function. Shown below
creativ13 [48]

Answer:

  (x, g(x)) = {(-2, -2), (0, 0), (2, 2), (4, -3), (6, -3)}

Step-by-step explanation:

The first three values of x in the table are all less than or equal to 2, so the first part of the function definition applies. The y-value is equal to the x-value. The ordered pairs are ...

  (-2, -2), (0, 0), (2, 2)

The last two values of x in the table are more than 2, so the last part of the function definition applies. For those values of x, the y-value is -3. The ordered pairs are ...

  (4, -3), (6, -3)
