Step-by-step explanation:

Given

3x - y = 2

Substitute y = x - 1 into the equation

3x - (x - 1) = 2

3x - x + 1 = 2 ← simplify left side

2x + 1 = 2 ← required equation after substitution

4. Represent the ordered pairs in the mapping diagram as a set of ordered pairs and as a table.

Firlakuza [10]

Answer/Step-by-step explanation:

✔️As a set of order pairs, the mapping can be represented as (x, y), where x = input and y = output.

Thus:

{(1, 6), (2, 6), (3, 6), (4, 8)}

✔️As a table we have input as x, and y as output, such as:

x | y

1 | 6

2 | 6

3 | 6

4 | 8

the amount of water in a bathtube as it drains can be modeled by this equation with y representing the number of gallons of wate

koban [17]

Since $y$ is representing the number of gallons of water in the tub, we need to replace $y$ with the number of gallons remaining in the tube to find the time. Fortunately, the problem is telling us just that: 17.8 gallons. The only thing left is replacing that value in the equation, and solve for $x$ to find the time:
$17.8=-7.3x+39.7$
$7.3x=21.9$
$x= \frac{21.9}{7.3}$
$x=3$

We can conclude that after 3 minutes <span>the tub will have 17.8 gallons of water remaining.</span>
