Answers
1st week 10 5
2nd week 20 10
3rd week 30 20
4th week 40 40
A) Amanda's method is linear because the number of minutes increased by an equal number every week.
common difference is 10.
1st week 0 + 10 = 10
2nd week 10 + 10 = 20
3rd week 20 + 10 = 30
4th week 30 + 10 = 40
Billy's method is exponential:
5(2)^x
1st week 5(2⁰) = 5(1) = 5
2nd week 5(2¹) = 5(2) = 10
3rd week 5(2²) = 5(4) = 20
4th week 5(2³) = 5(8) = 40

Answer: x ≤ 5 or x > 7
Step-by-step explanation:
First, we will write an equation for the left side. It's a closed dot going to the left (less than) of 5.
x ≤ 5
Next, we will write the right side. It's an open dot going to the right (greater than) of 7.
x > 7
Lastly, we will combine these to create our compound inequality.
x ≤ 5 or x > 7

365 days = 365*24 hours
365*24 hours = 365*24*60 minutes
2.2 million deaths / year
2.2 * 10^6 deaths / (365*24*60) minutes
4.186 deaths / minute
Answer: Approximately 4 deaths per minutes.
Step-by-step explanation:
Since, 1 year = 365 days,
1 day = 24 hours,
1 hour = 60 minutes,
⇒ 1 year = ( 365 × 24 × 60 ) minutes = 525600 minutes,
If the numbers of deaths in one year = 2.2 million = 2200000
⇒ The numbers of deaths in 525600 minutes = 2200000
⇒ The number of deaths in 1 minute = 2200000/525600 = 4.18569254186 ≈ 4
Hence, There are approximately 4 deaths per minutes.

Answers
Resriction u ≠ 6 and u ≠ 2 (because the denominator cannot be equal lto zero)
Simplification
u^2 - 4 is a difference of two squares, then you can factor it as the product of (u+2)(u-2). So, you can write the expression as:
(u+2)(u-2) / (u-2)(u-6)
Simplify u -2 (because it appears in the numerator and the denominator)
(u + 2) / (u -6), with u ≠2 and u≠6
