Here is your answer
The square root of a squared number, will be the number itself.
EXPLANATION:
Let
be a number.
Its square= ![{x}^{2}](https://tex.z-dn.net/?f=%7Bx%7D%5E%7B2%7D)
Now square root of this squared number= ![\sqrt{{x}^{2}}](https://tex.z-dn.net/?f=%20%5Csqrt%7B%7Bx%7D%5E%7B2%7D%7D%20)
= ![{x}^{2×\frac{1}{2}}](https://tex.z-dn.net/?f=%20%7Bx%7D%5E%7B2%C3%97%5Cfrac%7B1%7D%7B2%7D%7D%20)
= ![{x}^{1}](https://tex.z-dn.net/?f=%20%7Bx%7D%5E%7B1%7D%20)
= ![x](https://tex.z-dn.net/?f=%20x%20)
Hence, the initial number x is obtained.

8x + 5.5y = 78.5 would be ur equation for this situation...where x is the number of children's tickets she bought and y is the number of adult tickets she bought
Answer:
b
Step-by-step explanation:
The answer is y= 1 + 1x
because the slope is 1 shown by this table:
1,2
2,3
3,4
4,5
and if the slope is one then 2-1 is 1 and the y intercept is 0,1.
