It’s d since it’s asking about origin
2x-y=8...(1)
x+y=7....(2)
from (2)
y=7-x....(3)
put (3) into (1)
2x-(7-x)=8
2x-7+x=8
2x+x=8+7
3x=15
x=5.....(4)
put (4) into (2)
x+y=7
5+y=7
y=7-5
y=2
Hope it helps c:
Answer:

QAV = 36% * 360º = 129.6º
Answer:
see below
Step-by-step explanation:
We know that the center is (0,0) and the radius is |3 - 0| = 3.
Standard form of a circle: (x - h)² + (y - k)² = r² where (h, k) is the center and r is the radius. Plugging in h = 0, k = 0 and r = 3 gives us x² + y² = 9.
Answer:
![\frac{33}{50}](https://tex.z-dn.net/?f=%5Cfrac%7B33%7D%7B50%7D)
Step-by-step explanation:
Given: 2 1/5÷3 1/3
Rewrite as improper fractions:
÷ ![\frac{10}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B10%7D%7B3%7D)
"Keep, change, flip:"
* ![\frac{3}{10}](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B10%7D)
Multiply across: ![\frac{11 * 3}{5*10}= \frac{33}{50}](https://tex.z-dn.net/?f=%5Cfrac%7B11%20%2A%203%7D%7B5%2A10%7D%3D%20%5Cfrac%7B33%7D%7B50%7D)
Have a nice day!
