Hello there!

The number of people in different cities should be represented on a graph as Two-dimensional.

I'll explain why: The number of dimensions you need on a graph is equal to the number of variables that you are studying. In this case, you have two variables in the study:

1)The number of people
2)The city where they live

You'll need a two-dimensional graph with two axes in which one of the axes represents the number of people and the other axis represents the city. If you were also studying the age of those people, you'll need one more dimension to include this new variable.

Have a nice day!

Which table can be created using the equation below? –2 + 4x = y Answers are below.

Nikitich [7]

If you want you can rewrite the formula into slope intercept form so you don't get confused:
y=4x-2
Choice 1:
y=4x-2
y=4(-5)-2
y=-20-2
y=-22

y=4(0)-2
y=0-2
y=-2

y=4(3)-2
y=12-2
y=10

The best choice is the first one.
I hope this helped!

Diagram 1 shows absolute function of f(x)= 3x-1a)State the domain for that functionb)State the value of a

omeli [17]

The function given is,

$f(x)=3x-1$

a) Domain

This is the set of all points over which a function is defined.

Therefore, the domain of the function is

$-2\leq x\leq1$

b) Solving for the value of a

To solve for the value of a, the value of y = 0 at x = a

Therefore,

$\begin{gathered} f(x)=3x-1 \\ \text{where,} \\ f(x)=y=0 \\ x=a \end{gathered}$

Solving for a

$\begin{gathered} 0=3(a)-1 \\ 0=3a-1 \\ \end{gathered}$

Collect like terms

$\begin{gathered} 3a=0+1 \\ 3a=1 \end{gathered}$

Divide both sides by 3

$\begin{gathered} \frac{3a}{3}=\frac{1}{3} \\ a=\frac{1}{3} \end{gathered}$

Hence,

$a=\frac{1}{3}$

What process do you use to find the percent change of a quantity?

Sever21 [200]

First, we need to get the amount of change:
The amount of change can either be an increase or a decrease.
It can be calculated as follows:
amount of change = $\frac{"new"value - "old"value}{"old" value}$

If the amount of change is positive, then it is an increase
If the amount of change is negative, then it is a decrease

Then, we need to convert this amount into a percentage:
Changing the amount into a percentage can simply be done by multiplying this amount by 100
This means that:
% of change = amount of change * 100

Combining the two steps:
% of change = $\frac{"new"value - "old"value}{"old" value}$ * 100

Examples:
The original price of a certain product was $10. It then became $12. Find the % of increase.
% of change = $\frac{12-10}{10} * 100$ = 20%
This means that the price increased by 20%

The temperature decreased from 25 degrees to 20 degrees. Find the percentage of decrease.
% of decrease = $\frac{20-25}{25} * 100$ = -20%
This means that the temperature decreased by 20%

Hope this helps :)
