Step-by-step explanation:
![given \: equation \: is \: \\ {x}^{2} - 2x - 3 = 0 \\ by \: factorization \: we \: get \\ (x - 3)(x + 1) = 0 \\ x - 3 = 0 \\ x = 3 \\ x + 1 = 0 \\ x = - 1 \\ x = 3 \: \: or \: x = - 1 \\ value \: of {(x - a)}^{2} when \: x = 3 \: and \: a = 1 \\ {(3 - 1)}^{2} = {2}^{2} = 4 \\ if \: we \: substitute \: x = - 1 \: we \: get \: same \: answer](https://tex.z-dn.net/?f=given%20%5C%3A%20equation%20%5C%3A%20is%20%5C%3A%20%20%5C%5C%20%20%7Bx%7D%5E%7B2%7D%20%20-%202x%20-%203%20%3D%200%20%5C%5C%20by%20%5C%3A%20factorization%20%5C%3A%20we%20%5C%3A%20get%20%5C%5C%20%28x%20-%203%29%28x%20%2B%201%29%20%3D%200%20%5C%5C%20x%20-%203%20%3D%200%20%5C%5C%20x%20%3D%203%20%5C%5C%20x%20%2B%201%20%3D%200%20%5C%5C%20x%20%3D%20%20-%201%20%5C%5C%20x%20%3D%203%20%5C%3A%20%20%5C%3A%20or%20%5C%3A%20%20x%20%3D%20%20-%201%20%5C%5C%20value%20%5C%3A%20of%20%7B%28x%20-%20a%29%7D%5E%7B2%7D%20when%20%5C%3A%20x%20%3D%203%20%5C%3A%20and%20%5C%3A%20a%20%3D%20%201%20%5C%5C%20%20%7B%283%20-%201%29%7D%5E%7B2%7D%20%20%3D%20%20%7B2%7D%5E%7B2%7D%20%20%3D%204%20%5C%5C%20if%20%5C%3A%20we%20%5C%3A%20substitute%20%5C%3A%20x%20%3D%20%20-%201%20%5C%3A%20we%20%5C%3A%20get%20%5C%3A%20same%20%5C%3A%20answer)

Answer:
I don't know if you want to be a good
First we solve what we can solve.
<span>y</span>-3= 2/3<span>(</span>x-1)
We first multiply
<span>y</span>-3= 2/3 (x) - 2/3
Then we move the -3 and it becomes +3 on the other side
y= 2/3 (x) - 2/3 + 3
And we solve what we can to get our answer.
y= 2/3 (x) + 2 1/3
Answer:
option 1
Step-by-step explanation:
the square root of 6 is 2.44949, rounded it's 2.4
the square root of 42 is 6.48074, rounded it's 6.5
in option 1 the 6 is placed after the 2 because it is point 4, not quite 2 but a bit bigger than 2 but less than 3.
same thing for 42, it is placed after 6 because it is not quite 6 but not over 7. i hope this helped
