Answer:

yes, each input (x) has only one output (y)

Step-by-step explanation:

Answer:

aₙ = 2aₙ₋₁  for n ≥ 2
a₁ = 3

Step-by-step explanation:

A geometric sequence can be expressed recursively using the following general equation

aₙ = r . (aₙ₋₁), n ≥ 2
where
aₙ is the nth term
a₁ is the first term of the geometric sequence

r is the common ratio = aₙ/aₙ₋₁

Here we have the terms 3, 6, 12, 24, 48

The common ratio r = 6/3 = 12/6 = ....... = 48/24 = 2

The first term a₁ =  3

So the recursive relation is
aₙ = 2aₙ₋₁  for n ≥ 2
a₁ = 3

Step-by-step explanation:

To graph any point (±x, ±y) we must follow the steps as illustrated below.

The set of ordered pairings (x, y) where f(x) = y makes up the graph of a function.

These pairs are Cartesian coordinates of points in two-dimensional space and so constitute a subset of this plane in the general case when f(x) are real values.

Given, The points (- 4,- 4.5), (1, 2.5), and (- 2, - 0.5).

Now, To graph the point (-4, - 4.5) we should move 4 units left along the x-axis and down 4.5 units along the y-axis.

Similarly, for points (1, 2.5) and (- 2, - 0.5) we must follow the exact steps.

The graph of the points is shown in the attached image.

Based on the information given, the values are:

1. 80 rides

2. 53. 3%

3. 56. 6%

4. 30 students

Percentage can be defined as the ratio of a number to 100.

It is denoted with the symbol, '%'

How to determine the values;

1.. 24 rides = thirty percent of the total rides

Total rides = 24 rides/ 30%

Total rides = 24/ 30/ 100 = 24/ 0. 3 = 80 rides

2.  There are 14 Apple computers

16 PC computers

% of PC computers = 16/ 16 + 14 × 100/ 1

% of PC computers  = 16/ 30 × 100

% of PC computers  = 0. 53 × 100 = 53. 3

3.  3 out of 30 are not working

% of the working computers = 30- 3/ 30 × 100

% of the working computers = 17/ 30 × 100

% of the working computers = 56. 6

4.

If 12 students = 0. 4

Then x students = 1 - 0. 4 = 0. 6

cross multiply

x = 18 students

Total number of students = 40% + 60% of students = 18 + 12 = 30

Thus, the values are 80 rides, 53. 3%, 56. 6% , 30 students respectively.

Answer:

C. 2

Step-by-step explanation:

The equation that could represent a balanced hanger B, which is equivalent to hanger A, is: 6x + 3y = 3(3y + x).

Variables, which are alphabets represents unknown values and can be used in creating equations that model a scenario.

For example, in the model shown in the image, x represents the weight of each triangle while y = the weight of each square.

From the first balance, we can rearrange the squares and triangles to create hanger B.

The first equation is: 3(2x + y) = 9y + 3x

The second equation that can be created using the set of shapes would be:

6x + 3y = 3(3y + x)

Therefore, the equation that could represent a balanced hanger B, which is equivalent to hanger A, is: 6x + 3y = 3(3y + x).

The number of each type of jewellery she made is 12 earrings and 8 bracelet .

She sells earrings and bracelets on Etsy.

The earrings cost $5 a pair and bracelets cost $12.

She made 20 pieces on Saturday for $156.

let

x = number of pair of earring made

y = number of bracelets

Therefore, the system of equation that can be used to find the number of each jewellery she made can be calculated as follows;

5x +  12y = 156

x + y = 20

multiply equation(i) by 5

5x +  12y = 156

5x + 5y = 100

subtract equation(i) from equation(ii)

7y = 56

y = 56 / 7

y = 8

Hence,

x + 8 = 20

x = 20 - 8

x = 12

Therefore, the number of earring and bracelet she made are 12 and 8 respectively.

Answer:

b = 16

Step-by-step explanation:

the sum of the 3 angles in a triangle = 180°

sum the angles and equate to 180

b + 15 + 8b - 18 + 39 = 180

9b + 36 = 180 ( subtract 36 from both sides )

9b = 144 ( divide both sides by 9 )

b = 16

Answer: 1. (21/10 or 2.1). 2. (3/2 or 1.5)

Step-by-step explanation:

1. Let's take the first equation as an example (5 1/4 ÷ 2 1/2)

2. First, make both fractions improper (21/4, and 5/2)

3. Next, multiply the first fraction by the reciprocal (numerator and denominator swapped) of the second fraction. This is because, to keep the equation mathematically the same, we need to turn the division question into a multiplication question. In this case, it is 21/4 x 2/5 which answers 21/10, or 2.1.

4. Using the same method, we get 7/2 x 3/7, which is 3/2 (simplified), or 1.5.

Using proportions, it is found that the total length of the tree is of 194 inches. Three separate measurements are needed because it is only possible to add values measured in the same unit.

A proportion is a fraction of a total amount, and equations can be built to find the desired measures in the problem using a rule of three, that can be either direct(cross multiplication) or inverse(line multiplication), deriving from proportional relationships. One example of application of proportions is for unit conversion problems, as unit conversion involve rates between the variables.

For this problem, we have that the measurements in inches, considering the rates in the problem, are as follows:

Hence:

48 + 126 + 20 = 194 inches.

The total length of the tree is of 194 inches. Three separate measurements are needed because it is only possible to add values measured in the same unit.
