The answer to your question would be 17y + 7.

To figure this out, you would have to use the distributive property to solve. Multiply 7 by 2y to get 14y.

Next, multiply 7 by 1 to get 7. And since there are like terms, add them together.
14y+3y=17y. And there is still a 7 that we need to put into the equation. Which would be 17y+7

Have a Merry Christmas!!✨❤️

What are the texture of metamorphic​
Flauer [41]

Answer:

This seems to be a Geography question, However, I am answering. The Metamorphic rock textures lies in two larger groups. They are the Non-Foliated and the Foliated.

Explanation:

The answer above explains everything. However, we need to understand the Foliation, and exactly what it is. It is actually developed in the rock through parallel alignment of various minerals(platy), like muscovile, chlorite and biotite, as well as minerals which are needle type such as homblende or feldspars, which are the various tabular minerals.

xeze [42]

Answer:

<u> FlashCard.java</u>

  1. public class FlashCard {
  2.    String Question;
  3.    String Answer;
  4.    public FlashCard(String q, String a){
  5.        this.Question = q;
  6.        this.Answer = a;
  7.    }
  8.    public String toString(){
  9.        String output = "";
  10.        output += "Question: " + this.Question + "\n";
  11.        output += "Answer: " + this.Answer;
  12.        return output;
  13.    }
  14.    public boolean equals(String response){
  15.        if(this.Answer.equals(response)){
  16.            return true;
  17.        }
  18.        else{
  19.            return false;
  20.        }
  21.    }
  22. }

<u>Main.java</u>

  1. public class Main {
  2.    public static void main(String[] args) {
  3.        FlashCard card1 = new FlashCard("What is highest mountain?", "Everest");
  4.        FlashCard card2 = new FlashCard("What is natural satelite of earth?", "Moon");
  5.        FlashCard card3 = new FlashCard("Who is the first president of US?", "George Washington");
  6.        FlashCard cards [] = {card1, card2, card3};
  7.        for(int i=0; i < cards.length; i++){
  8.            System.out.println(cards[i]);
  9.        }
  10.    }
  11. }

Explanation:

In FlashCard.java, we create a FlashCard class with two instance variable, Question and Answer (Line 2 - 3). There is a constructor that takes two input strings to initialize the Question and Answer instance variables (Line 5-8). There is also a toString method that will return the predefined output string of question answer (Line 10 - 15). And also another equals method that will take an input string and check against with the Answer using string equals method. If matched, return True (Line 17 -24).

In Main.java, create three FlashCard object (Line 3-5) and then put them into an array (Line 6). Use a for loop to print the object (Line 8-10). The sample output is as follows:

Question: What is highest mountain?

Answer: Everest

Question: What is natural satelite of earth?

Answer: Moon

Question: Who is the first president of US?

Answer: George Washington
