Answer:
10 years
Step-by-step explanation:
Let c and s represent the populations of Canyon Falls and Swift Creek, respectively. For time t in years, the respective populations are ...
c = 22500 -740t
s = 15200 +1500t
We want to find t when s = 2c.
s = 2c
15200 +1500t = 2(22500 -740t)
2980t = 29800 . . . . . add 1480-15200, simplify
29800/2980 = t = 10 . . . . divide by the coefficient of t
The population of Swift Creek will be double that of Canyon Falls in 10 years.
Answer:
3.
Step-by-step explanation:
f(-2) = 3(-2)^2 + 4(-2) - 1
= 12 - 8 - 1
= 3.
<span>'x' can be anything. There's no information here to say that it must be
one thing or another. You can't find 'x', because there is no
equation.
You can probably simplify the fraction by doing some factoring, but
there's
no way to tell a value for 'x'. As long as 'x' is not -4, it can be anything, and
its value determines the value of the fraction.</span>
