M= 1 y intercept is 0 I think
Answer:
Step-by-step explanation:
1) x - 21x = 5
x = x * 1
21x = x * 21
GCF = x
x - 21x = 5
x*(1 -21) = 5
x * (-20) = 5
-20x = 5
x =5/-20
x = -1/4
2) 6n² = 6 * n * n
30n = 6 * 5 * n
GCF = 6*n = 6n
6n² + 30n = 0
6n*(n + 5 ) = 0
6n = 0 or n + 5 = 0
n = 0 n = -5
n = 0 or -5
Answer: -8
Step-by-step explanation: First add one to both sides. Now you're left with −2(x+3)=10. Then divide both sides by 2 and simplify 10/2 to 5. Next, subtract 3 from both sides (-5-3). Finally, -5-3 is 8 because -5-3 is the same as -5+-3. When you add 5+3, you get 8. However, since your adding two negatives, you end up with -8. I hope this helped you!!!!!!
Answer:
x^2
Step-by-step explanation:
The formula we should use here is (a+b)^2=a^2+2ab+b^2
Using this we should first squared 36, getting us 6
Then divide -12x by 6, getting us -2x
Then we divide-2x by -1, getting us 2x
Lastly we divide 2x by 2 to get x
x is our original factors, but to fit in the equation, we need to square it
The last seems most appropriate
