12 600
Step-by-step explanation:
the highest i hope it is helpfull my answer thank you
The point is at an x value of -2 and it goes up the imaginary axis 3 units, so the imaginary part of the complex number is 3i.
Hiiiiiiiiiiiiiiiiiiiiiiiii
So basically, the first question after the word problem is asking you to write an equation to represent the value of Mama's car after a certain amount of years (t). Since the value of her car decreases by 3% each year, you could multiply 3% by the original value of her car, to find what 3% is, OR you could subtract 19,400 (the value of her car after 1 year) from 20,000 INSTEAD of multiplying 20,000 by 3%.
Equation: value=20,000 - 600t
To answer the next question, just plug it into the equation you created.
500<20,000 - 600t
-19500< -600t
32.5>t
Final Answer: It would take at least 32 and 1/2 years for the value of Mama's car to be less than $500.
Hope this helps!! :)
