2. The probabilities of drawing a spade and a heart are (with no substitute):
P(Spade) * P(Spade) = (13 / 52) * (13 / 51) = 169 / 2652 = 0.06372. You have a
fine beginning on finding the probability. Once you find the probability, you need

6. From the graph, if x = 1, y = 1
We get the identical value by substituting in the equation:
y = -4*1 + 5
y=18. From the graph, when y = -3, x = 2
Utilizing the equation, -3 = -4x + 5
-8 = -4x
=> x = 2 12. 5x + 20y = 60
x + 4y =
