Answer:
(3, 18)
Step-by-step explanation:
When we have a system of equations like:
y = f(x)
y = g(x)
The solutions of that system are the points (xₙ, yₙ) such that:
yₙ = f(xₙ)
yₙ = g(xₙ)
This means, if we graph these functions, the solutions are the points where the graphs intersect.
Then we just need to find points (xₙ, yₙ) that belong to both functions.
In this case, we have two tables, the first thing we need to do is see if there is a common coordinate pair in these tables, if there is, then that is the solution.
If there is not a common coordinate pair, then we need to use the data in the tables to find the functions for each one, and then find a solution in the way that we explained above.
By looking at the table in the image, we can see that the coordinate pair:
(3, 18)
is in both tables.
Then, this point is the solution of the system.
