Answer:
All real numbers are solutions
Step-by-step explanation:
Let's solve your equation step-by-step.
8x−6=2x−6+6x
Step 1: Simplify both sides of the equation.
8x−6=2x−6+6x
8x+−6=2x+−6+6x
8x−6=(2x+6x)+(−6)(Combine Like Terms)
8x−6=8x+−6
8x−6=8x−6
Step 2: Subtract 8x from both sides.
8x−6−8x=8x−6−8x
−6=−6
Step 3: Add 6 to both sides.
−6+6=−6+6
0=0
The population Pa of insect A after t years is given by the equation
Pa = 1.3(1-0.038)^t
while the population Pb of insect B after t years is
Pb = 2.1(1-0.046)^t
We equate the above expressions to find the number of years t it will take the two populations to be equal:
Pa = Pb
1.3(1-0.038)^t = 2.1(1-0.046)^t
1.3(0.962)^t = 2.1(0.954)^t
These are the equations that can be used to determine how long it will be before the populations of the two species are equal.
We can now solve for t:
(0.962)^t / (0.954)^t = 2.1/1.3
(0.962/0.954)^t = 2.1/1.3
After taking the log of both sides of our equation, number of years t is
t = log (2.1/1.3) / log (0.962/0.954)
t = 57 years
Therefore, it will take 57 years for the population of insect A to equal the population of insect B.
