Answer:
y = 1/2
x = -3/2
Step-by-step explanation:
y = 3x+5
Substance instances of y in the equation.
x + 3x +5 = -1
4x=-6
x= -6/4
y = 1/2
Answer:
x = 10
Step-by-step explanation:
Divide both sides by 2.
(2x) / 2 = 20 / 2
x = 10
Answer:
- Decay rate, r = 0.014
- Initial Amount =120,000

- P(10)=104,220
Step-by-step explanation:
The exponential function for growth/decay is given as:

In this problem:
The city's initial population is 120,000 and it decreases by 1.4% per year.
- Since the population decreases, it is a Decay Problem.
- Decay rate, r=1.4% =0.014
- Initial Amount =120,000
Therefore, the function is:

When t=10 years
