Answer:
D. f(x) = 2x - 8
Step-by-step explanation:
What you do is you take the x number and but it into the x spot.
f(x) = 2x Put 5 into the x
2(5) = 10 does not equal 2.
f(x) = x -3 Put 5 into the x
5 - 3 = 2, but if you plug a different x into it, it doesn't work.
D. f(x) = 2x - 8 is your answer.
Answer:
75%
Step-by-step explanation:
9 ÷ 12 = 0.75
0.75 = 75%
Answer:
k = 5
Step-by-step explanation:
Now comparing left hand side & right hand side ,
Cancelling x^2 & 6 from both left hand side & right hand side ,
kx = 5x
=> k = 5
Answer:
top right corner
Step-by-step explanation:
Answer:
14.2 years
Step-by-step explanation:
The multiplier of the population each year is 1 +5% = 1.05, so after n years the population has been multiplied by 1.05^n. You want to find the value of n that makes this expression equal to 2:
2 = 1.05^n
log(2) = n·log(1.05) . . . . . take logarithms
log(2)/log(1.05) = n ≈ 14.2
Growing at a rate of 5% per year, it will take about 14.2 years for the population to double.
