Answer:
f^-1(x) = x + 5
Step-by-step explanation:
f(x) = x-5
y = x-5
Exchange x and y
x = y-5
Solve for y
x+5 = y-5+5
x+5 =y
The inverse is x+5
Assuming that this is a linear relationship you must find the rate of change...$23.81-$20.70= $3.11. 3.11 is how much it changed that year. What that also gives you is how much you bought the post for at 0 years by subtracting $20.70 and the $3.11 = the price of the poster. This gives us the equation y=3.11(x)+17.59
Where Y is the value and X is the amount of years.
Answer:
Linear: y = 2x-1
Step-by-step explanation:
slope 1 = (5 - -9)/(3 - -4) = 14/7 = 2
slope 2 = (19-5)/(10-3) = 14/7 = 2
equation: y = mx + b b = y-mx = 19 - 2*10 = -1
y = 2x - 1
Population are often modelled by exponential functions
The population will reach 1000000 people after 26.5 years
The population function is given as:
When the population reaches 1000000 people, we have:
P(x) = 1000000
So, the equation becomes
Divide both sides by 692600
Take logarithm of both sides
Apply logarithm to both sides
Make x the subject
Solve the logarithms of 1.444 and 1.014
Divide
The value of x, is the number of years the population reaches 1000000 people.
Hence, the population will reach 1000000 people after 26.5 years

The <u>correct answer</u> is:
16/45.
Explanation:
We want the probability that a student's eye color is blue if they made an A in physics. This means we look at the column for students with an A.
There are 32 students with blue eyes in the A column.
This is out of 32+58=90 students that made an A.
This makes the probability 32/90, which simplifies to 16/45.
