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:

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.

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

Answer and Step-by-step explanation:

We are asked to turn this fraction ([tex]\frac{9}{10}[/tex]) into an equivalent fraction, but with a denominator of 100.

[tex]\frac{9 <- Numerator}{10<-Denominator}[/tex]

All we have to do is multiply the numerator and denominator by 10, since 10 times 10 equals 100.

[tex]\frac{9}{10} * \frac{10}{10} = \frac{90}{100}[/tex]

The answer is:

[tex]\frac{90}{100}[/tex]

Question might be incomplete or incorrect so we'd have to assume Mateo took apples

Answer:

5/189 apples

Step-by-step explanation:

If Carlos picks 6/384 apples then there must be 384 apples available to pick from. Amount of apples left after Carlos picks =384-6=378 apples

If Mateo picks 10 apples after Carlos then how much apples Mateo has taken would depend on the number of apples available, hence the fraction of apples Mateo has taken = 10/378

Reduce to lowest terms to get 5/189 apples

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:

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:

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

second one

Step-by-step explanation:

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:

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:

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:

Number 1

Step-by-step explanation:

Because the absolute Value of A is less then the value of B

Step-by-step explanation:

Given information :

Mr. Gonzalez drove 30 miles in March. In January, she drove 1/5 as much as in March.

30 ÷ 5 = 6 miles in January

in JanuaryShe drove 2 times as many miles in February as she did in January. In January, she drove 30 miles.

6 x 2 = 12 miles in February

Answer:

x= 2.4

Step-by-step explanation:

Answer:

2.4 or 12/5

Step-by-step explanation:

1.2/0.96=3/x

convert the decimal into a fraction---- 6/5 /0.96= 3/x

Simplify the complex fraction-----5/4 = 3/x

simplify the equation using cross-mulitpication----- 5 x = 12

divide both sides of the equation by 5--- x= 12/5

Check if the solution is in the defined range

Answer:

20 2 3 6 10 998778889899999

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
