Answer:
Step-by-step explanation:
4b + 8 = 20
Subtract 8 from both sides
4b + 8 - 8 = 20 - 8
4b = 12
Now divide both sides by 4
4b/4 = 12/4
b = 3
Check:
LHS = 4b + 8
= 4*3 + 8
= 12 + 8
= 20 = RHS
We have the vertex (-4, -1), therefore we have:
Based on time conversion, the age of a teacher who is 50 years old in seconds is 1577880000 seconds.
<h3>What is the age of a teacher who is 50 years in seconds?</h3>
The age of the teacher in years is converted to seconds as follows:
- 60 seconds = 1 minute
- 60 minutes = 1 hour
- 24 hours = 1 day
- 3651/4 days = 1 year
Thus:
50 years to seconds will be:
50 × 365.25 × 24 × 60 × 60 = 1577880000 seconds.
Therefore, the age of a teacher who is 50 years old in seconds is 1577880000 seconds.
