The system of equations that can be used to determine the number of tetra fish and goldfish purchased is:
x = 2 y. 2 x + 1.5 y = 20
<h3>What are the system of equations ?</h3>
In order to determine the required values, two linear equations would be formed from the question. The two equations would exhibit the relationship between the two types of fishes:
The first equation would show the ratio between the two types of fishes bought: 2y = x
Th second equation would show the total cost of the two type of fish:1.5y + 2x = 20

These points show that this is not going to be a linear line. This is actually a parabola.
I find that the function rule is going to be

1st,2nd,3rd,4th that is your answer
Angles 1 and 3 are vertical lines and because they are vertical, both angles equal each other.
