Asuming the added image is part of the complete question...
Answer:
C) rectangle C
Step-by-step explanation:
Observing the image we can see that when the rectangle C is reflected across the x-axis and then moved up 2 units, it will land exactly where the rectangle E is.
I hope you find this information useful and interesting! Good luck!
Answer:
3
-1/3
Step-by-step explanation:
up 3 right 1
down 1 right 3
Y = k/x for some fixed number constant k
7 = k/9
k = 63
so Y = 63/x
14 = 63/x
14 x = 63
x = 63/14 = 9/2
P(winning) = 4/52 = 1/13
P(losing) = 48/52 = 12/13
Expected value
= 1/13 ($498) + 12/13 (−$2)
= $498/13 − $24/13
= $474/13
= $36.46
A) D + Q = 15
B) .10 D + .25Q = 2.85
Multiplying equation A by -.10
A) -.10 D -.10 Q = -1.5 Then adding this to B)
B) .10 D + .25Q = 2.85
.15Q = 1.35
9 Quarters
and if there are 15 coins there are 6 dimes
