Let x represent number of redwood trees and y represent number of spruce trees.
We have been given that a park ranger bought 12 trees. We can represent this information in an equation as:
We are also told that redwood trees cost $24 each, so cost of x redwood trees would be .
Each spruce tree costs $16, so cost of y spruce trees would be .
Since the park ranger spent $208 on trees, so we can represent this information in an equation as:
Upon substituting equation (1) in equation (2), we will get:
Therefore, the park ranger bought 2 redwood trees.
Upon substituting in equation (1), we will get:
Therefore, the park ranger bought 10 spruce trees.
B is the right answer according to the result of the equation. "<em>Thanks</em><em> </em><em>me</em><em>"</em><em> </em>if i've been helpful
Answer:
The expression used to represent g(x) as inverse of f(x) is
Option B is correct.
Step-by-step explanation:
We are given:
We need to find the expression that could be used to verify g(x) is the inverse of f(x).
We know that is inverse of function
So placing value of f(x) in g(x)
So, the expression used to represent g(x) as inverse of f(x) is
Option B is correct.
We can also solve to prove that
