Answer:
(x+y+z)=79
5x+2y+z=859
2x+3y+9z=498
Step-by-step explanation:
Its writing 3 different equations that have the same value for the same variable.
The function f(x) = 4(4)x represents the growth of a fly population every year in a remote swamp.
calculates three times a year, not just once a year.

3 times a year
so x becomes 3x


Take log on both sides


Use log property and move exponent before log

Divide both sides by x
log 4 = 3 log(1+r)
Solve for '1+r'
log 4 = log(1+r)^3
Remove log from both sides
4 = (1+r)^3
take cube root on both sides
1.584740= 1+r
1+r = 1.59

so equation becomes

1+r = 1.59
subtract 1 from both sides
So r= 59 = 59%
So growth factor is 59%
Answer is option C
10/14 = 5/7.
5/7 is your answer. Divide both the numerator and the denominator by a number that they both have in common - 2.
Answer:
We end up with our original number
Step-by-step explanation:
Let x be our number
We increase by 100
increase = old number * 100%
increase = x*1
increase = x
New number = old number + increase
= x+x
=2x
Now we decrease by 50%
decrease = number *50%
= 2x*.5
=x
Final number = new number - decrease
= 2x-x
=x
