Is the relation a function? Explain

Answers

Answer 1

Answer:

No, does not pass the vertical line test

Step-by-step explanation:

Answer 2

Answer:

No.

Step-by-step explanation:

A function is a relation in which that one x-value (input) is related to exactly one y-value (output). For relations shown on graphs, we can use the vertical line test.

Since the line would intercept at 2 points in the graph at one point, it is not a function.

10. Shown here is the graph of which inequality?

Answers

Answer:

B) 3x +2y >= 6

Step-by-step explanation:

Shannon ran the race slower than Patti but faster than Phan. What might her time be?

Phan: 7.7
Daniel: 7.44
Patti: 7.1
Ida: 7.501
Maisha: 7.01
Ali: 7.941
Manuel: 7.332

Answers

Since she was slower than Patti but faster than Phan, the compound inequality that models her time t is:

[tex]7.1 < t < 7.7[/tex]

An inequality is said to be compounded if it includes two terms, for example:

[tex]a < x < b[/tex]

Which has the following interpretation: x is more than a and x is less than b.

In this problem:

Shannon is slower than Patti, hence her time is greater than 7.1.She is also faster than Phan, hence her time is less than 7.7.

Then, the inequality is:

[tex]7.1 < t < 7.7[/tex]

(b) 25 - x = 15 - (3x + 10)
(c) 4x = 2x + 2x + 5 (x - x)

Answers

Answer:

Step-by-step explanation:

(a) 2x + 4 (x - 1) = 2 + 4x

2x +4x - 4 = 2 + 4x

6x -4 = 2 + 4x

2x = 6

x = 3 One solution

(b) 25 - x = 15 - (3x + 10)

25 - x = 15 - 3x - 10

2x = 15 - 25 - 10

Han and Priya were making a kite. Han cut out a piece of fabric so

that there were 2 short sides of the same length on top and

2 long sides of the same length on the bottom. Priya cut 2 pieces

of wood to go across the diagonals of the kite. They attached the

wood like this:

Han asked Priya to measure the angle to make sure the pieces of

wood were perpendicular. Priya said, "If we were careful about

the lengths of the sides of the fabric, we don't need to measure

the angle. It has to be a right angle."

Complete Priya's explanation to Han.

Answers

A kite is a quadrilateral which has two equal adjacent sides. Therefore measuring the lengths accurately would make the pieces of wood perpendicular. Since the diagonals of a kite are at right angle to each other.

Quadrilaterals are shapes which has four straight sides. Examples are; square, trapezium, kite, rectangle etc.

A kite is a shape which has adjacent sides to have equal lengths. It has two diagonals, and one line of symmetry.

The lengths of the sides of the fabric being exact imply that the pieces of wood would be perpendicular as suggested by Priya when fixed appropriately to the piece of fabric. This is because the diagonals of a kite are always perpendicular. Thus measuring the angles as suggested by Han is not necessary.

The 2 pieces of wood intersect at right angles if the length of sides of the fabric are measured correctly.

Since Priya said to Han that "If we were careful about the lengths of the sides of the fabric, we don't need to measure the angle. It has to be a right angle."

Priya used the properties of a kite.

Since from the properties of a kite, two pairs of sides are equal. Also, since thes two pairs of sides are equal, the diagonals from the vertices of the kite intersect at right-angles.

So, as Priya said to Han, the angle made by the 2 pieces of wood have to be right angles if the sides are measured correctly, since the diagonals intersect at right angles.

So, the 2 pieces of wood intersect at right angles if the length of sides of the fabric are measured correctly.

PARALLEL PERPENDICULAR OR NEITHER

Answers

Answer:

Parallel

Step-by-step explanation:

Using these points, we can determine that the equation is as follows:

Line B: y = -2/3x + 7/3

And since Line A has the same slope, it would make Line A's equations like this:

Line A: y = -2/3x - 11/3

This makes these equations Parallel to each other because they have the same slope with different y-intercepts.

The members of a book club spend the same amount of money for refreshments at each meeting. At one meeting they bought 6 bagels and spent $9.00 on beverages. At the next meeting they bought 8 bagels and spent $8.20 on beverages. What was the cost of each bagel?

Answers

The members of a book club spend $0.4 for each Bagel as refreshment.

Let x represent the cost of each bagel.

At a meeting, they bought 6 bagels and spent $9.00 on beverages, hence:

Cost = 6x + 9

At another meeting, they bought 8 bagels and spent $8.20 on beverages, hence:

Cost = 8x + 8.20

Since the same money is spent on each meeting, hence:

6x + 9 = 8x + 8.2

2x = 0.8

x = $0.4

Therefore the cost of each bagel is $0.4

Explanation:

If x repeats itself, then we don't have a function. For instance, relation 2 has the x value -4 show up twice. That input leads to multiple outputs which is why we don't have a function. Relation 4 is a similar story (this time the input 'u' shows up twice).
