A linear function is a function that has constant average rate of change;

Also, a relation that represents a function must have unique input and output values.

<h3>Question 11: Relations and Functions</h3>

A relation may or may not represent a function.

When the domain and the range of a relation are unique, then the relation is a function.

So, the true option is (b) function

<h3>Question 12: Relations and Functions</h3>

A one-to-many relation is not a function.

This is so because the domain and the range of the function are not unique

So, the true option is (c) figure 3: one-to-many.

<h3>Question 13: Variables</h3>

A dependent variable is a variable that depends on other variables for its value.

In this case, the dependent variable is (b) boosts the immune system.

<h3>Question 14 and 15: Domain and Range</h3>

The domain is the set of input values (i.e. the x values), while the range is the set of output values (i.e. the y values)

This means that:

The domain of the function is: (a) {2,3,4,5,6}
The range of the function is: (b) {4,6,8,10,12}

<h3>Question 16 and 17: Linear functions</h3>

The graph of a linear function is represented by a straight line, and it has a constant slope or rate.

This means that:

Graph C is a linear function
Table B is a linear function

<h3>Question 18: The table</h3>

The fare of 3 km and 5 km are given as 35 pesos and 55 pesos, respectively.

This means that:

Table (b) represents the information

<h3>Question 19: The linear equation</h3>

Start by calculating the slope (m) using:

$m = \frac{y_2 -y_1}{x_2 -x_1}$

So, we have:

$m = \frac{55-35}{5-3}$

$m = \frac{20}{2}$

$m = 10\\
$

The linear equation is then calculated as:

$y = m(x -x_1) + y_1$

This gives

$y = 10(x -3) + 35$

$y = 10x -30 + 35$

$y = 10x +5$

This means that:

The linear equation that describes the relationship is (c) $


$ $


$ $y = 10x +5$ ; $x \ge 2$

<h3>Question 20: The fare when the distance is 4km</h3>

This means that x = 4.

So, we have:

$y = 10 \times 4 +5$

$y = 45$

Hence, the fare will be (a) 45 pesos

What number is 26.8% of 67.5?<br> and<br> 325% of what is 78.65?

miss Akunina [59]

Well this is easy, just take the percentage as an actual number and just multiply
26.8% as a number is 0.268 (if you don't know how I got this, just divide that percentage by 100, and a 1.00 is equal to a 100%) and 0.268 * 67.5 is 18.09.
(You can round that)
Now 325% as a number is 3.25 (it's bigger than 100% so its increasing)
3.25 * 78.65 is <span>255.6125.</span>

1. A survey of visitors at a national park was conducted to determine the preferred

fiasKO [112]

Using proportions, it is found that the correct statement is:

D. The number of visitors who prefer camping will be 2 times the number of visitors who prefer water sports.

<h3>What is a proportion?</h3>

A proportion is a fraction of a total amount.

In this problem, the table is from a sample of 80 visitors.

Since the <u>proportions stay the same</u>, just the number of visitors change, the correct statement is given by:

D. The number of visitors who prefer camping will be 2 times the number of visitors who prefer water sports.

As from the 80 students, 28 prefer camping and 14 prefer water sports, hence from 200, these numbers will be of 70 and 35 respectively.

Write a recursive formula for the explicit formula.

Setler79 [48]

Answer: A

Step-by-step explanation:

$A_n=9+(n-1)*(-4)\\\\A_1=9+(1-1)*(-1)=9+0=9\\\\A_{n-1}=9+((n-1)-1)*(-4)\\\\A_n-A_{n-1}=9+(n-1)*(-4)-(9+(n-2)*(-4))=-4n+4+4n-8=-4\\\\\boxed{A_n=A_{n-1}-4}\\\\\\Answer\ A$
