Hello there!
First of all, I like your profile picture!
1) There's a lot of different methods for solving a system of equation. But here are my three favorite.
- Graphing
- Substitution (Which I preferred to use and I think it is easier).
- Elimination
2) When solving a system of equations, you can get;
- One solution
- No solution
- Infinite number of solution
3) The graphing method help solving a system of equation by knowing that the solution to a system of equations is the point of intersection of the two lines.
I hope this answer helps. As always, it is my pleasure helping student like you!
If you round it to the nearest ten thousand it would be 380,000
Answer:
1. Communitave property
2. communitave property
3.
1. distribute 2 to x and 10 to get ride of parenthesis
2. subtract 2x from the left to move it to the right so x is by itself
3. add 15 to both sides to cancel it out on one side, and move to the other.
4. divide by 5 on both sides so you can get the value of x
5. flip equation so it is in the x equals form
4.
1. distribute 2 to the x and positive 3 on the left side, also distribute -4 to both x and -1 , to get rid of our parenthesis.
2. add 4x to both sides so it cancels out on one side and moves to the other ( our xs and numbers need to be on opposite sides)
3. subtract 4 on the left side to move it to the right side because again numbers on the right and letters on the left
4. divide by 6 on both sides of the equation to solve for x
Answer:
12
Step-by-step explanation:
Slope=y2-y1/x2-x1
Slope=9-(-3)/-1-(-2)
Slope=12/1
Slope=12
