Answer is a because -1 just means the opposite
Okay on what? I would be happy to help you
Answer:
5
Step-by-step explanation:
Let :
x(1) be 2
y(1) be 5
x(2) be -2
y(2) be 2
We know that distance between any 2 points is equal to:-
![\sqrt{{(x(2) - x(1) )}^{2} + ({y(2) - y(1))}^{2} }](https://tex.z-dn.net/?f=%20%5Csqrt%7B%7B%28x%282%29%20%20-%20x%281%29%20%29%7D%5E%7B2%7D%20%2B%20%20%28%7By%282%29%20-%20y%281%29%29%7D%5E%7B2%7D%20%7D%20)
So using the above formula ,
![\sqrt{ {( - 2 - 2)}^{2} + {(2 - 5)}^{2} }](https://tex.z-dn.net/?f=%20%5Csqrt%7B%20%7B%28%20-%202%20-%202%29%7D%5E%7B2%7D%20%2B%20%20%7B%282%20-%205%29%7D%5E%7B2%7D%20%20%7D%20)
![= > \sqrt{ {( - 4)}^{2} + {( - 3)}^{2} }](https://tex.z-dn.net/?f=%20%20%3D%20%20%3E%20%5Csqrt%7B%20%7B%28%20-%204%29%7D%5E%7B2%7D%20%2B%20%20%7B%28%20-%203%29%7D%5E%7B2%7D%20%20%7D%20)
![= > \sqrt{16 + 9}](https://tex.z-dn.net/?f=%20%20%3D%20%20%3E%20%5Csqrt%7B16%20%2B%209%7D%20)
![= > \sqrt{25} = 5](https://tex.z-dn.net/?f=%20%3D%20%20%3E%20%20%5Csqrt%7B25%7D%20%20%3D%205)
1000 = 2p + 250
p = poster
1000 - 250 = 750
750 = 2p
750/2 = 375
p = 375
375 posters can be printed for $1000.
