Alright, for the two equations you gave me, which are x=y+4 and y=x+4, we can try substitution to get the answer! Substitution is when you take one variable from one equation and plug it into another equation to find out what both variables are!
To do this, we start with the first equation, x=y+4. Then, from the second equation we know that y=x+4 so we can plug x+4 in for the y in the first equation. We now have x=(x+4)+4 as our first equation.
Now, we can simplify! The parenthesis aren't important in this equation, so we can just get rid of them, giving us x=x+4+4. Now we can simplify to give us x=x+8. Now, all that's left is to subtract the x from both sides of the equation! This gives us 0=8, but we know that that's not possible because there is no way that 0 can equal 8. This means that this equation doesn't have an answer!
To check this, you can repeat the steps above with the second equation, but you will still end up with 0=8, and that, again, means that this equation doesn't have an answer.
30 divided by 6 gives you the amount of laps which would be 5 laps
Answer:
(x^87*(x^2+4))/54
Step-by-step explanation:
Answer:
-1
Step-by-step explanation:
Square root 1 is 1. Add that to the 12 to get 13. Subtract 13 from both sides to get: -5x = 5. Divide both sides by -5 to get your answer: -1
Steps:
1. Substitute the y in y=4x + 4 and put
X-6=-4x+4
2. Add 4x to both sides
3. 5x-6=4
4. Add 6 to both sides
5. 5x=10
6. Divide by 5 on both sides
7. X=2
8. Now to find the y, you substitute 2 for x in the problem y=x-6
9. Y=2-6
10. Y=-4
11. Your answer is
(2, -4)
