Which set of ordered pairs does not represent a function?

B. { (3, –2), (3, –4), (4, –1), (4, –3) }
C. { (3, –2), (4, 3), (5, –4), (6, –5) }
D. { (3, –2), (6, –2), (9, –2), (12, –2) }

Answers

Answer 1

Answer:

B. { (3, –2), (3, –4), (4, –1), (4, –3) }

Step-by-step explanation:

Functions are a set of points that show how dependent variables change through independent variables.

Defining a Function

In functions, each x-value is assigned to exactly one y-value. This means that x-values do not repeat. So, if there is one x-value more than once in a set, then it cannot be a function.

For example, set B has the x-value 3 and 4 repeated twice. Thus, it does not represent a function.

Graph of a Function

Functions can also be defined through a graph. Just like with coordinate points, x-values do not repeat on the graph. You can use the vertical line test to see if a graph is a function. If you can draw a vertical line at every point on a graph without it ever intersecting with the graph more than once, then it is a function.

What is a Triangle ?

A triangle is a polygon with three sides , angles and vertices

It is given that

There are 8 triangular windows

The base of the triangle is 12 inches

The height of the window is 14 inches

Area of the triangle is (1/2) * base * height

Area of the triangle = (1/2) * 12 * 14

Area of the triangular window is 84 sq. inches

Area of the 8 Triangular windows is 8 * 84 = 672 sq.ft

James is at a gift sale where everything costs $4 (tax included).
James has $50.
James must have at least $28 remaining when he is finished buying
gifts.
What is the greatest number of gifts James can buy?

Answers

Answer:

total money = 50

money remained = 28

money can be used = 50 - 28 = 22

Max item that can be purchased = 22 ÷ 4 = 5

+ 2 remainder.

items buy = 5

total money left = 30

Answer:

5 gifts

Step-by-step explanation:

Given information:

Cost of one gift = $4Total money = $50Money left after purchasing gifts = at least $28

Let x = greatest number of gifts James can buy

Create an inequality with the given information:

⇒ 50 - 4x ≥ 28

Solve the inequality

Add 4x to both sides:

⇒ 50 - 4x + 4x ≥ 28 + 4x

⇒ 50 ≥ 28 + 4x

Subtract 28 from both sides:

⇒ 50 - 28 ≥ 28 + 4x - 28

⇒ 22 ≥ 4x

Divide both sides by 4

⇒ 22 ÷ 4 ≥ 4x ÷ 4

⇒ 5.5 ≥ x

⇒ x ≤ 5.5

We must round down to 5 as if James buys 6 gifts, he will only have $26 remaining. Therefore, the greatest number of gifts James can buy is 5 gifts.

A triangle has an angle that measures 10°. The other two angles are in a ratio of 7:10. What are the measures of those two angles?

Answers

Answer:

100 degrees and 70 degrees

Step-by-step explanation:

180 - 10 = 170

with a ratio of 7:10

7x + 10x = 170

17x = 170

x = 170/17

x = 10

one angle in 100 degrees and the other is 70 degrees

lily pads increase by 25% every 10 days.if a pond starts with 22 lily pads how many will there be after 50 days?

Answers

Answer:

Step-by-step explanation:

22 (1 + .25) 5

22 ( 1.25 ) 5

3.05

3.05 x 22

=67

There are 67 pads after 50 days

How to determine the number of pads?

The given parameters are:

Initial, a = 22

Rate, r = 25% every 10 days

There are 5 ten days in 50 days.

So, the number of pads after 50 days is:

Pad = 22 * (1 + r)^5

Substitute 25% for r

Pad = 22 * (1 + 25%)^5

Evaluate

Pad = 67.13

Approximate

Pad = 67

Hence, there are 67 pads after 50 days

Answer:

I am not sure.. But I guess it is option D

Step-by-step explanation:

Answer:

the 4th answer

Step-by-step explanation:

well, any negative number up to leading to a 0 in the denominator will create a result <= 0.

because the numerator with x² will be positive. and the denominator with x will be negative.

so, it has to be the third or the fourth answer.

but then the 3rd answer includes -infinity in the interval ("["). and that cannot be right.

so, it leaves the 4th answer as the only possible right answer.

just as an additional quick check : large positive numbers for x will always create posits results for this fraction, so the 1st and 2nd answers do not fulfill the <=0 condition.

How to determine the total cost?

The given parameters are:

Cost = £320

VAT = 45/2 %

The total cost is calculated as:

Total = Cost * (1 + VAT)

Total = £320 * (1 + 45/2%)

Evaluate the product

Total = £392

Hence, the cost of the computer including VAT is £392

Answers

Answer: slope = 6/15

Step-by-step explanation:

▪︎ Slope = rise / run

▪︎ Rise = y2 - y1

▪︎ Run = x2 - x1

☆ Two points: (-7, -2) and (8, 4)

=> Rise = 4 - (-2) = 4 + 2 = 6

=> Run = 8 - (-7) = 8 + 7 = 15

=> Slope = 6/15
