Use the relation S { (3,4) , (2,3), (1,2), (2,1)} for questions 1 and 21. State the domain and range of S
2. Is S a function? Explain your reasoning.

Answers

Answer 1

Answer:

Answer:

HOPE THIS HELPS!!

Step-by-step explanation:

1. The domain and range of relation S are as follows:

Domain: The domain refers to the set of all input values in a relation. In this case, the domain of S is {3, 2, 1}, which corresponds to the first element of each ordered pair in the relation.

Range: The range refers to the set of all output values in a relation. In this case, the range of S is {4, 3, 2, 1}, which corresponds to the second element of each ordered pair in the relation.

2. No, relation S is not a function.

To be considered a function, each input value (or element in the domain) should have only one corresponding output value (or element in the range). However, in the given relation S, the input value 2 is associated with both the output values 3 and 1.

Since one input value is associated with multiple output values, S fails the definition of a function.

The lines are parallel. Find the slope-intercept form of the equation y₂.

Answers

Since the lines are parallel and you know the slope of $y_(1)$ is -2, you know the slope of line $y_(2)$ will also be -2. You can see on the coordinate grid that line $y_(2)$ crosses the y-axis at -1. When you piece all of these facts together into slope-intercept form you get $y_(2)$ = -2x - 1.

2. Hessa was playing a computer game. She scored 43 points in Round 1 and 26 points in Round 2. Which sum could she use to add the points together? a. 40 + 20 + 3 + 6 b. 4 + 3 + 2 + 6 c. 40 + 30 + 20 + 60 d. 30 + 4 + 60 + 2

Answers

Answer:

a. 40 + 20 + 3 + 6

Step-by-step explanation:

Points scored by Hessa is as shown below;

Round 1 = 43 points

Round 2 = 26 points

Total points for both rounds = 43 + 26 = 69 points

To determine the sum she could use to add the points together, we must select the sum that will give us the same total of points for both rounds i.e 69 points.

The Round 1 score (43 pt)can also be expressed as (40+3) points

The Round 2 score (26 pt)can also be expressed as (20+6) points

The sum she could use to add the points together will be (40+3)+(20+6)

which is also equal to 40 + 20 + 3 + 6 = 69points

Hence, option a is correct
