Original height=10 feet
Height after first bounce: (10 feet)*90%=(10 feet)*90/100=9 feet
Height after second bounce: (9 feet)*90%=(9 feet)*90/100=8.1 feet
Height after third bounce: (8.1 feet)*90%=(8.1 feet)*90/100=7.29 feet = 7.3 feet
Height after fourth bounce: (7.29 feet)*90%=(7.29 feet)*90/100=6.561 feet=6.6 feet

Answer: Option <span>B) 9, 8.1, 7.3, 6.6,...</span>

PLEASE HELP LOTS OF POINTS!!!!!!!! TWO QUESTIONS!!!!!!!!!
zubka84 [21]

Answer: Number one would be 3x+2y+-14 and x+y=-4, second one is x=-3, y=7

Step-by-step explanation:

The first one is solved by inputting the x and y in each one and finding which one comes out true, the second on is solved by substitution. to find x you would subtract x in the first equation and make it y=4-x then input that equation in the y in the second equation.
