Answer:
(x,y) ⇒ (x - 3) (y - 4)
C(5, -1)
Step-by-step explanation:
For this case, the first thing we must do is define variables:
x: number of quarters
y: number of nickels
We now write the system of equations:
x + y = 68
0.25x + 0.05y = 13.40
Solving the system we have:
x = 50
y = 18
Answer:
they have:
quarters = 50
nickels = 18
Answer: <u><em>A, because when x=1/-1 you don't need to write down the one meaning it is -x and then +2 is the y which means the full answer is y=-x+2</em></u>
Total cards = 52
Total kings = 4
P(2 kings) = (4/52)(4/52) = 1/169
Answer : 1/169
