The solution to the equations is x=20 and y=40

Step-by-step explanation:

Let,

Small tier = x

Medium tier = y

According to given statement;

1.The situation with a system of equations.

3x+y = 100 Eqn 1

3x+2y=140 Eqn 2

2. Solving the System of equations;

Subtracting\ Eqn\ 1\ from\ Eqn\ 2\\(3x+2y)-(3x+y)=140-100\\3x+2y-3x-y=40\\y=40\\Putting\ value\ of\ y\ in\ Eqn 1;\\3x+40=100\\3x=100-40\\3x=60\\Dividing\ both\ sides\ by\ 3\\\frac{3x}{3}=\frac{60}{3}\\x=20

The solution to the equations is x=20 and y=40

True or false is a relation in which each y value has only 1 x value
boyakko [2]

Answer:

The statement is true that a function is a relation in which each y value has ONLY 1 x value.

Step-by-step explanation:

The statement is true that a function is a relation in which each y value has ONLY 1 x value.

The reason is very clear that we can not have the repeated x-values (two same x-values).

For example, given the set of the ordered pairs of a relation

{(3, a), (6, b), (6, c)}

As the same x values (x=6) has two different Y values. Hence, the stated relation is not a function.

In order to be a function, a relation must have only 1 x-value for each y-value.

Therefore, the statement is true that a function is a relation in which each y value has ONLY 1 x value.
