Charles has a collection of pennies and dimes worth $0.26. He has 8 coins. Select the TWO EQUATIONS below that make up the system of equations that represents this situation where x represents pennies and y represents dimes.

x+y=8x plus y is equal to 8

x−y=8x minus y is equal to 8

x+y=0.26x plus y is equal to 0 point 2 6

0.01x+0.10y = 0.260.01x+0.10y = 0.26

0.01x+0.10y = 8 , 0.01x+0.10y = 8

0.01x−0.10y = 0.26

Which of the following best describes the graph below? a. it is a function, but it is not one-to-one. b. it is a one-to-one function. c. it is not a function. d. it is a many-to-one function.
