Barbie spent $166 on clothes. She bought some shirts that cost $14 each and some pants that cost $22 each. She bought a total of 9 items. Select the system of equations to determine how many shirts and pants Barbie purchased. Let x represent the number of shirts and y represent the number of pants. x + y = 166

14x + 22y = 9

x + y = 166, , 14x + 22y = 9,

x + y = 9

22x + 14y = 166

x + y = 9, , 22x + 14y = 166,

x + y = 9

14x + 22y = 166

x + y = 9, , 14x + 22y = 166,

x + y = 36

166x + 9y=14x + 22y

the answer to the question is a  

it has the same slope and the same y-intercept.

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !

answer: all of the odd numbers were opened

the first person was the one that was opening all of the lockers. since one is odd, this causes all of the odd number lockers to be opened in the end.
