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.

How can you solve the literal equation y-3x=13
ser-zykov [4K]
So to begin, you need to find x and y. If you have answer options, plug those in. If you don't, your toast. Just kidding :) 
So, your answer would be y3=13. I think you can handle the rest. 3 * what equals 13?

How do you find the answer to this?
Stels [109]

Answer:

  D)  {-1}

Step-by-step explanation:

A rational expression is "not defined" when its denominator is zero. Hence to find values of x that make the expression "not defined," you solve the equation ...

  denominator = 0

  2x +2 = 0 . . . . . . put the actual denominator into the equation

  x + 1 = 0 . . . . . divide by 2

  x = -1 . . . . . . . . subtract 1

The expression is "not defined" for x in the set {-1}.
