Slope is 2 because it goes up by two and over by one
Let's find f(g(x)):
f(x) = 2/x. Let's replace the two instances of x with g(x) = 2/x:
2
f( g(x) ) = --------------- = x. Thus, we have shown that f and g are inverses.
(2/x)
For this case we have a function of the form:
Where,
A: initial value of an autographed baseball
b: growth rate
x: number of years
Substituting values we have:
For the moment when the value is at least 650 $ we have the following inequality:
Answer:
a one-variable inequality that could be used to solve for the number of years, x, it would take for the baseball to be worth at least $650 is:
Answer:
The bear is 35 years of old now.
Step-by-step explanation:
Leon wanted to know the age of the black bear at the zoo.
He is informed that if he adds 10 years to the age of the bear and then doubles it, the bear would be 90 years old.
Let the present age of the bear is x years.
So, according to the above condition we can write
2(x + 10) = 90
⇒ 2x + 20 = 90
⇒ 2x = 70
⇒ x = 35
So, the bear is 35 years of old now. (Answer)
