Which of the following situations models a geometric sequence? select all that apply.

Options 1, 3, 4.

Step-by-step explanation:

We will check each and every option given here.

1) Amount of cell phone users increases by 33% every year.

Its a geometric sequence because the number of users are increasing exponentially every year.

2) Amount of cakes in bake sale increases by 3 each year the fundraiser is held.

amount of cakes is increasing with a common difference of 3 so it's an arithmetic sequence.

3).Uranium loses half of its weight every 415 years.

Exponential decay in every 415 years. So geometric sequence with a common ratio of 1/2.

4).A family of rabbits doubles in size every 3 months.

Exponential series again so geometric sequence with a common ratio of 2.

5).Car drives at a constant speed of 58 mph.

Its a linear function representing an arithmetic sequence with a common difference of 58 mph.

6). Number of students increases by 122 every year.

An arithmetic sequence with a common difference of 122.

7). Number of pieces of chalk in a class room decreases by 10 throughout the school year.

It's an arithmetic sequence having common difference of 10.

step-by-step explanation:

x = -4

step-by-step explanation:

- 20 - 4(x + 3) = 4x

=> -20 - 4x - 12 = 4x

=> - 32 -4x = 4x

=> -32 = 4x + 4x

=> - 32 = 8x

=> -32/8 = x

=> -4 = x
