Answer:

Explanation:
d(x) = -2x - 6
to find the inverse of a function, you need to follow these steps:
1. set d(x) = y
2. interchange the variables, so y becomes x and x becomes y
3. solve the equation for y
<u>step 1:</u> set d(x) = y
y = -2x -6
<u>step 2:</u> interchanging the variables
y = -2x - 6 turns into x = -2y - 6
<u>step 3:</u> solving for y
x = -2y - 6 < add 6 to both sides to get rid of it on the right
x + 6 = -2y < divide both sides by -2 to get y alone
x + 6 / -2 = 
-2y / -2 = y
= y
so the inverse of the function is 
The three options that describe the typographic hierarchy are given below:
- The importance of information is shown through the text.
- The presentation of the text in terms of structure.
- The placement of the text defines its flow and hierarchy.
Thus, the correct options are A, B, and C.
<h3>What is Typographic hierarchy?</h3>
Typographic hierarchy may be characterized as an approach that utilizes typography: the size, font, and layout of distinct text components to produce a hierarchical division that can authenticate users where to look for specific information.
The purpose of using this methodology is to focus on the main points of the article accordingly. It increases the sense of understanding of the readers with focus.
Therefore, it is well described above.

Answer:C)User interface
Explanation: User interface(UI) is the interaction phase of the user or programmer with the computer system and network. This phase helps the user to connect with the operating system function and let them process it according to the requirement. Example-monitor , keyboard, mouse etc.
Other options that are given are incorrect because operating system is the system that is part of the interface , information is the data and storage is for the storing of data,.Thus the correct option is option(C)
Answer:
iron
Your water might be affected by iron, which is a commonly-occurring constituent of drinking water. Iron tends to add a rusty, reddish-brown (or sometimes yellow) color to water. If the color is more black than red, your water might contain a combination of iron and manganese.
