a.
Use the domain and range of each of the following relations to determine which is a function.
{3, 7, - 7,9}
b. {(3,9), (7. - 4), (-7,7)}
• {(3,9), (7. - 4), (37)
d. {(3,9), (7. - 4), (7,6), (-7, 7)}
Please select the best answer from the choices provided

Answers

Answer 1

Answer:

Option B.

Step-by-step explanation:

A relation is called a function if there exist unique value of y for each value of x.

In option (a), \(\{3,7,-7,9\}\) is set not a relation.

In option (b), \(\{(3,9),(7,-4),(-7,7)\}\) is function because there exist unique value of y for each value of x.

In option (c), \(\{(3,9),(7,-4),(3,7)\}\) is not function because there exist two value of y, which are 9 and 7, for x=3.

In option (d), \(\{(3,9),(7,-4),(7,6),(-7,7)\}\) is not function because there exist two value of y, which are -4 and 6, for x=7.

Therefore, the correct option is B.

Answer 2

Here are the ones to pick from
1. -2 + -2 +6 +x
2. 6(-2 +x)
3. 6(-2 +x)
4. -3 (1 - 2x)

Answers

Answer:

Option #4

Step-by-step explanation:

Expand option #4

=-3(1-2x)

=-3 -2x*-3

=-3+6x which is what your original equation was.

becoz it is a multiple choice, we can go by elimination, hence when we expand #4, we will get -3+6x

You have to look at both x and y and it’s power. You have to look for the lowest power for x and y. For y as you can see that the lowest power is 2. As for x it can be either power of 3 or even 2. When you removed x^2 and y^2 from the equation. The inside parenthesis will be x^2-3xy. Just remember when you divide both x^2 and y^2, you subtract the power.

When you get the answer, please check the answer if it’s the same as the original. Meaning distribution both x^2 and y^2 to inside parenthesis. And for the power, you add them. This way you can double check and see if it’s the same.

cassie is placing stickers on a page that is 12 inches long and 8 inches wide the sticker are 3 inches long and 2 inches wide

cassie is placing stickers on a page that is 12 inches long and 8 inches wide the sticker are 3 inches

Answers

Answer:

To find the greatest number of stickers Cassie can place on a page that is 11 inches long and 8 inches wide without them overlapping, we need to use the same approach as before.

Firstly, we need to calculate the maximum number of stickers that can fit along the length of the page, which is now 11 inches. Since each sticker is 3 inches long, we can fit 3 stickers along the length (11 ÷ 3 = 3 with a remainder of 2).

Next, we can calculate the maximum number of stickers that can fit along the width of the page, which is still 8 inches. Since each sticker is 2 inches wide, we can fit 4 stickers along the width (8 ÷ 2 = 4).

To ensure that the stickers do not overlap, we can only use the full row of 3 stickers from the previous calculation. Therefore, we can place 3 stickers along the length and 4 stickers along the width, giving us a maximum of 12 stickers that Cassie can place on the page without them overlapping.

Step-by-step explanation:

Answer:

16

Step-by-step explanation:

First, find out how much stickers you can put on the long side:

12/3 = 4

Next, find out how much stickers you can put on the wide side:

8/2 = 4

Lastly, calculate them together:

4x4=16

So the answer is 16.

Answers

answer: 1/7

the formula for slope is rise over run, or y1-y2 divided by x1-x2. we can choose either number as y1 or y2 but it needs to stay consistent with x

so let’s plug in from your table.

0-1 divided by -7 -0
(you could also do 1-0 divided by 0-(-7))

-1/-7 which equals 1/7

so, your slope is 1/7

Which expression is equivalent to -1/3 ( 6x + 15 ) - 3?
a) -2x + 12
b) -2x + 2
c) -2x - 2
d) -2x - 8​

Answers

The correct answer is (D) -2x - 8.

To simplify the expression -1/3 ( 6x + 15 ) - 3, we can first apply the distributive property to the term in parentheses:

-1/3 ( 6x + 15 ) - 3 = -1/3 * 6x - 1/3 * 15 - 3

Then we can simplify using the properties of multiplication and division:

-1/3 * 6x - 1/3 * 15 - 3 = -2x - 5 - 3

Finally, we can combine like terms:

-2x - 5 - 3 = -2x - 8

The correct answer is therefore (D) -2x - 8.✅

The graph that represents the function g(x) = 2(0.5)ˣ -1 is given.

What is graph?

In mathematics, a graph is a visual representation or diagram that shows facts or values in an ordered way.

The relationships between two or more items are frequently represented by the points on a graph.

Given expression,

g(x) = 2(0.5)ˣ -1

To draw the graph take x = 0, 1,2, -1 , -2 and so on .

And draw these numbers in the graph.

Take x=0

g(0) = 1

the point is (0,1)

And now , take x = 1

g(1) = 0

the point is (1,0)

Take x =-1

g(-1) = 3

The point is (-1,3)

Therefore, the graph is given in the image.

Answer:

Step-by-step explanation:

Hope this helps! :)

Answer:  \(4\sqrt{3}\)  (choice A)

========================================

Work Shown:

\(\sqrt{48} = \sqrt{16*3}\\\\\sqrt{48} = \sqrt{16}*\sqrt{3}\\\\\sqrt{48} = 4\sqrt{3}\)

The idea is to factor 48 such that one of the factors is the largest perfect square possible. So that's why we go with 48 = 16*3. Then we use the rule \(\sqrt{x*y} = \sqrt{x}*\sqrt{y}\) to break up the root.

Each subject is taught by a different teacher, so students change classrooms every period. Students don’t have a class every period, but every student has a homeroom class. Consider five samples from this population, then answer the questions that follow. Sample A: Survey four random students in each of Rima's classes. Sample B: Survey two random students from each homeroom class. Sample C: Survey three random girls from every third-period class. Sample D: Survey every sixth person in the student directory. Sample E: Survey every third person in the band directory. Part A Is sample A a random sample? Why or why not?

PART A: Sample A is not a random sample. In a random sample, all members of the population have an equal chance of being selected. Sample A has students from Rima’s classes, but no students from other classes. Students from the other two grades in the school won’t be represented.

PART B: Sample B is a random sample. Every student, or every member of the population, has a homeroom class. All of them have an equal chance of being selected in the sample.

PART C: Sample C is not a random sample because the sample excludes boys. The sample should include both girls and boys to represent the entire student population.

PART D:  Sample D is a random sample. All students in all grades are featured in the student directory, so all of them have an equal chance of being picked for the sample.

PART E: Sample E is not a random sample because it consists of only the students in the band and excludes all other students from the sample. Because not every student is in the band, this is not a fair representation of the entire student body.
