Step-by-step explanation:

Answer:

[tex]\{(2,8),(2,1),(-9,-5),(-8,9)\}[/tex] is not a function

Step-by-step explanation:

Given

[tex]\{(-3,-1),(8,-1),(0,-5),(-9,-2)\}[/tex]

[tex]\{(5,9),(-3,-5),(0,4),(-9,9)\}[/tex]

[tex]\{(9,0),(-5,4),(5,0),(6,3)\}[/tex]

[tex]\{(2,8),(2,1),(-9,-5),(-8,9)\}[/tex]

Required

Which is not a function

A function is of the form [tex](x,y)[/tex]

Assume a function is:

[tex]\{(x_1,y_1),(x_2,y_2),(x_3,y_3).....,(x_n,y_n)\}[/tex]

In simple terms:

For an ordered pair to be regarded as a function, no x value must be repeated

Analyzing the options:

1. [tex]\{(-3,-1),(8,-1),(0,-5),(-9,-2)\}[/tex]

This is a function because none of the x values (-3, 8, 0 and -9) appeared more than once

2. [tex]\{(5,9),(-3,-5),(0,4),(-9,9)\}[/tex]

This is a function because none of the x values (5, -3, 0 and -9) appeared more than once

3. [tex]\{(9,0),(-5,4),(5,0),(6,3)\}[/tex]

This is a function because none of the x values (9, -5, 5 and 6) appeared more than once

4. [tex]\{(2,8),(2,1),(-9,-5),(-8,9)\}[/tex]

This is not a function because one of the x values (2) appeared more than once.

i.e.

[tex](2,8)[/tex]   and   [tex](2,1)[/tex]

Answer:

128

Step-by-step explanation:

Top Triangle

Let the base angles of the top triangle = y

y + 102 = 180

y = 78

The vertex

Is found by adding the two base angles together and subtract that from 180

y + y + vertex = 180

78 + 78 + vertex = 180

156 + vertex = 180

vertex = 180 - 156

vertex = 24 degrees

Bottom Triangle

Because the base angles are connected by a vertically opposite angle on the bottom triangle, both base angles are 26

Therefore 26 + 26 + x = 180

52 + x = 180

x = 180 - 52

x = 128

Answer:12 beads

Step-by-step explanation: If she has 48 beads and wants to make 4 bracelets, you will have to divide 48 by 4 which gives you 12

Answer:

22 people saw an horror movie

Step-by-step explanation:

Total people who attended the Sunday matinee = 48

People who saw romantic comedy = 3/8 of 48

= 3/8 × 48

= (3*48) / 8

= 144 / 8

= 18 people

People who saw action movie = 1/6 of 48

= 1/6 × 48

= 48/6

= 8 people

People who saw horror movie = x

Total people who attended the Sunday matinee = People who saw romantic comedy + People who saw action movie + People who saw horror movie

48 = 18 + 8 + x

48 = 26 + x

Subtract 26 from both sides

48 - 26 = 26 - 26 + x

22 = x

x = 22 people

22 people saw an horror movie

Answer:

2 answers are true

Step-by-step explanation:

If no adult chaperones were needed, 30 students could go to the zoo. Is true

If 16 adults go to the zoo, then 6 students can go. Is also true

An equilateral polygon has congruent sides, like a rhombus.

An equiangular polygon has congruent interior angles, like a rectangle.

In other words: Equilateral doesn't necessarily have congruent INTERIOR angles while equiangular does have/need congruent interior angles.

A = lw

~~~~~~~~~~~~~

Part A:

2[(4x - 6) + 12] = 36

8x- 12 + 24 = 36

8x = 36 - 12

x = 3

Part B:

A = 6 × 12 = 72 inch.²

Answer:

2,500 students

Step-by-step explanation:

If the population has increased by 25%, the total population of the school is now 125% of what it used to be. Then to figure it out, you find out 125% of 2000 which is 2,500 students!

Answer:

x=35; y=55; z=55

Step-by-step explanation:

x+y=90; z+x=90

z+35=90

z=90-35= 55

x=90-55= 35

y= 90-35 =55

Answer:

The estimate is 186.5 seconds.

Step-by-step explanation:

To calculate the estimate of the time the racing car will take to travel 10 miles, we have to first find the ratio of the original distance to the requested distance.

The number of seconds in an hour is [tex]60 \cdot 60[/tex] seconds, which equals to 3600 seconds.

[tex]\frac{193}{10} = \frac{3600}{x}[/tex]

[tex]19.3 = \frac{3600}{x}[/tex]

[tex]x = \frac{3600}{19.3}[/tex]

[tex]x \approx 186.5[/tex]

Hence, the estimate is 186.5 seconds.

Answer: A) 90.75 ft.

Step-by-step explanation: because if we cut 10 from 100 we will get 90

Answer:

3335 chairs

Step-by-step explanation:

To find the total number of chairs, multiply 29 by 115, since there are 29 rows that have 115 chairs:

29(115)

= 3335

So, the auditorium has 3335 chairs in all

Answer: 3335 Chairs

Work: So, the question already gave us how many seats are there per row, now we need to find out how many are there in 29 rows. You multiply 115 by 29 to find out how many seats are there, and you get 3335 chairs. I hope this helps you, and stay safe. :)

Answer: the answer is 1.6

Step-by-step explanation: 8 divided by 5 is 1.6

Answer:

14

Step-by-step explanation:

When you sqaure a number you multiply it by itself once so it would be (3x3) + 5. Rmemeber PEMDAS, so you multiply 3x3 first to get 9 and then you add 5 to get 14.

Answer:

12.41m

Step-by-step explanation:

Well, if we divide by the hypotenuse of the Pythagorean Theorem due to the angle created between the divisions on the scale between the 8th and 7th degree law of the Mathematical Institution of Nigeria, Ghana and Ethiopia (MINGE), then we get the result of 12.41.

Answer:

equation 1

y = -2x

equation 2

y = x-3

Solution to both

(1,-2)

Step-by-step explanation:

We need to get the equations of both lines

General form is;

y = mx + c

where m is slope and c is the y-intercept

Table 1

since we have a point 0,0; the y-intercept here is zero

Let us get the slope. We can do this by selecting any two points

m = (y2-y1)/(x2-x1)

m = (2-10)/(-1+5) = -8/4 = -2

So the equation of the first line is;

y = -2x

Table 2

we get the slope

m = (4+2)/(7-1) = 6/6 = 1

The partial equation is;

y = x + c

To get c, we select any two point and substitute

4 = 7 + c

c = 4-7

c = -3

So the equation is;

y = x-3

To get the solution to both systems, we equate the y

-2x = x - 3

-2x-x = -3

-3x = -3

x = -3/-3

x = 1

To get y, we substitute;

recall; y = -2x

y = -2(1)

y = -2

Solution to the system is;

(1,-2)
