Which of the sets of ordered pairs represents a function? (5 points) A = {(1, −5), (8, −5), (8, 7), (2, 9)} B = {(7, −4), (7, −2), (6, −3), (−9, 5)} Only A Only B Both A and B Neither A nor B

Answers

Answer 1

Answer:

We conclude that Neither A nor B represents the function.

Hence, the correct option is:

Neither A nor B

Step-by-step explanation:

A function relates an input to an output.

For example, a certain animal grows 30 cm each year. Thus, the height of the animal is associated with its age using the function

h (age) = age × 30

Therefore, if the age of the animal is 3 years, the height is:

h(3) = 3 × 10 = 90 cm

Set A

A = {(1, −5), (8, −5), (8, 7), (2, 9)}

Please check that there are duplicated inputs.

i.e. x = 8 is appeared twice.

Thus, set A does not represent the function because the function has repeated inputs or x-values. In other words, each input is not related to exactly one output.

Therefore, the set A of ordered pairs does not represent a function.

Set B

B = {(7, −4), (7, −2), (6, −3), (−9, 5)}

Please check that there are duplicated inputs.

i.e. x = 7 is appeared twice.

Thus, the set B does not represent the function because the function has repeated inputs or x-values. In other words, each input is not related to exactly one output.

Therefore, the set B of ordered pairs also does not represent a function.

Conclusion:

We conclude that Neither A nor B represents the function.

Hence, the correct option is:

Neither A nor B

Answers

On a coordinate plane, the point (0,20) is graphed.

Here’s why:
You can rewrite the equation as y=1/4x+20 and 20 is an y-intercept point and the coordinate is (0, 20)
Remember that the coordinates are written (x,y).

What are the coordinates of the point on the directed line segment from (3, -3) to
(7,5) that partitions the segment into a ratio of 5 to 3?

Answers

Answer:

(5.5, 2)

Step-by-step explanation:

Points given:

(3, -3) and  (7,5)

Partition ratio:

5 to 3

Formula for the point:

x = x1 + a/(a+b)×(x2 - x1) y = y1 + a/(a +b)×(y2 - y1)

So the points are:

x = 3 + 5/(5+3)×(7-3) = 3 + 5/8×4 = 5.5y = -3 + 5/8×(5 - (-3)) = -3 + 5/8×8= 2

Find the maximum value of
P = x + 6y
subject to the following constraints:
(2x + 4y < 10
X + 9y < 12
x > 0
y0
P = [?]

Answers

Answer:

(3, 1)

Step-by-step explanation:

Given the following constraints:

2x + 4y ≤ 10

x + 9y ≤ 12

x ≥ 0

y ≥ 0

We have to first graph the above constraints and secondly, we find the  boundary points for the feasible region. This is done by plotting the graphs of 2x + 4y ≤ 10  and x + 9y ≤ 12.

 From the graph, the following points satisfy the constraints:

(0,0) , (3,1) , (0,4/3) , (5,0)

Given that:

P = x + 6y

For (0, 0): P = x + 6y = 0 + 6(0) = 0

For (3, 1): P = x + 6y = 3 + 6(1) = 9

For (0, 4/3) P = x + 6y = 0 + 6(4/3) = 8

For (5, 0) P = x + 6y = 5 + 6(0) = 5

The graph shows the cost of buying tickets to a concert.
a. What does the point (4,122) represent?
b.What is the unit rate?
c.What is the cost of buying 10 tickets?

Answers

Answer:

a) The point (4, 122) represents that the cost of 4 tickets is $122

b) The unit rate is 30.5 dollars per ticket

c) The cost of buying 10 tickets is $305

Step-by-step explanation:

Let us solve the question

From the given graph

∵ The x-axis represents the number of tickets

∵ The y-axis represents the cost of tickets in dollars

∴ The line represents the relationship between the number of tickets

   and their cost

a)

∵ The point (4, 122) lies on the line

∴ x = the number of tickets

∴ y = their cost

x = 4 and y = 122

∴ The cost of the 4 tickets is 122 dollars

The point (4, 122) represents that the cost of 4 tickets is $122

b)

∵ The unit rate is the slope of the line

The slope of the line = Δy/Δx, where

Δy = y2 - y1 Δx = x2 - x1

∵ The line passes through points (0, 0) and (2, 61)

x1 = 0 and x2 = 2

y1 = 0 and y2 = 61

→ Substitute them in the rule of the slope above

The slope of the line = [tex]\frac{61-0}{2-0}[/tex] = [tex]\frac{61}{2}[/tex] = 30.5

The unit rate is 30.5 dollars per ticket

c)

∵ The linear equation is y = m x + b, where

m is the slope of the line b is the y-intercept (value y at x = 0)

m = 30.5 ⇒ the slope of the lone

b = 0 ⇒ The line passes through the origin point (0, 0)

∴ The equation of the line is y = 30.5x

x = 10 ⇒ number of tickets

→ Substitute x by 10 in the equation to find the cost of 10 tickets

∴ y = 30.5(10)

y = 305

The cost of buying 10 tickets is $305
