2th bounce- 80
5th Bounce- (-)200
9th Bounce- (-)560

Every time the ball bounces it loses 40cm because on the first bounce 160cm-120cm=40cm
And the score goes down by 40 every time and since we go into the negatives the negatives sometimes add on top of each other

On Gabriela’s first birthday, her parents gave her a $50 savings account. On every birthday after that her parents added to the
valkas [14]

Answer: a_1=50,d=25 and $475 deposited into the account on her birthdays by her 18th birthday.

Step-by-step explanation:

It is given that, on Gabriela’s first birthday, her parents gave her a $50 savings account.

Initial term : a_1=50

On every birthday after that her parents added to the account, increasing the amount they deposited by $25 each year.

Common difference : d=25

It forms an AP: 50,75,100,...

nth term of an AP is

a_n=a_1+(n-1)d

Substitute a_1=50 and d=25 in the above formula.

a_n=50+(n-1)25

It represents the amount deposited into the account after n birthdays.

We need to find the amount by her 18th birthday.

Put n=18 in the above equation.

a_{18}=50+(18-1)25

a_{18}=50+(17)25

a_{18}=50+425

a_{18}=475

Therefore, $475 deposited into the account on her birthdays by her 18th birthday.

kakasveta [241]

Answer:

X= 5/12 + 1/24y  

Y= -10 + 29x

Step-by-step explanation:

2(10- 24x)+ 2y                          2(10- 24x)+ 2y

20 - 48x +2y                            20 - 48x +2y

48x =20 +2y                            -2y = 20- 48x

/48   /48  /48                           /-2    /-2    /-2

x= 5/12 + 1/24y                         y= -10 +29x
