Answer:
the common ratio is 0.98.
Step-by-step explanation:
A fish population in a lake decreases by 2% each year. We are asked to find the common ratio.
The decrease of population of fish 2% annually means the population becomes next year 100% - 2% = 98%
Therefore, the common ratio would be 98%. Upon converting 98 percent to a decimal we will get,
98% =
Therefore, the common ratio or decay factor is 0.98.
We have two equations and two unknowns/variables
y = 2x + 4
y = x + 2
We can solve by substitution or by elimination.
Let's try substitution.
Since both equations are set equal to y, set the two equations equal to one another and solve for x.
x + 2 = 2x + 4
Use algebra to solve
x = -2
Now use this value of x in one of the original equations to solve for y.
y = x + 2
y = -2 + 2
y = 0
So the solution is (-2,0).
