2x + y = 3
3x - y = 12
Add both equations
5x = 15, x = 3
2(3) + y = 3
6 + y = 3, y = -3
Solution: x = 3, y = -3... or (3,-3)
Answer:
Step-by-step explanation:
The first time the basketball bounces it reaches a height of 
.
The second time the basketball bounces it reaches a height of ![(0.722) (0.722) (6) = [(0.722) ^ 2] (6)](https://tex.z-dn.net/?f=%280.722%29%20%280.722%29%20%286%29%20%3D%20%5B%280.722%29%20%5E%202%5D%20%286%29)
. Therefore, after b rebounds the height that the basketball will reach is given by:
Answer:
Middle: 2.5 ft
Right: 4,375 ft
Left: 1,875 ft
Step-by-step explanation:
We know that a tree in the middle is 2.5 feet tall.
Now the tree on the left measures 3/4 of the tree in the middle, therefore:
2.5 * 3/4 = 1.875
Which means that the tree on the left is 1.875 feet tall.
Finally the tree on the right 1 3/4, which would be 1.75 times the tree in the middle, therefore:
2.5 * 1.75 = 4.375
Therefore the tree on the right is 4.375 feet tall.
