Answer:
a = - 25
Step-by-step explanation:
Given that:
4a+6+16=-9(2+12a)-10(1-11a)
By simplifying:
- Adding like terms and multiplying constants into the bracket
- Negative sign will change the signs in the brackets
4a + 22 = -18 - 108a- 10 +110a
4a + 22 = -28 + 2a
- Taking terms with "a" to left side and others to right
- Signs of transferred terms will be changed
4a - 2a = -28 - 22
- Both terms on right side have negative sign so they wil be added and answer will have negative sign.
2a = -50
- Dividing both sides by 2 we get
a = -50/2
- Reducing to lowest term (dividing both by 2)
a = -25/
I hope it will help you!
Answer:
The population will be 863 in the next eight years
Step-by-step explanation:
Here, we want to know the population of the town in 8 years, given the percentage decrease and the present population
The exponential equation to use is that;
P = I( 1 - r)^n
where P is the future population we want to calculate
I is the present which is 2,400
r is the percentage of decay given as 12% = 12/100 = 0.12
n is the number of years which is 8
Substituting these values, we have that
P = 2,400(1 - 0.12)^8
P = 2,400(0.88)^8
P = 863
