A. When you go left, you are going negative and when you go up, you are going positive
Can y’all answer my recent question and i’ll answer this plz
Step-by-step explanation:
Given
for first circle, center is at
and radius is
units
General equation of circle with center (h,k) and radius r units is given by
![\Rightarrow (x-h)^2+(y-k)^2=r^2](https://tex.z-dn.net/?f=%5CRightarrow%20%28x-h%29%5E2%2B%28y-k%29%5E2%3Dr%5E2)
for the given circle it is
![\Rightarrow (x-3)^2+(y-2)^2=2^2\\\Rightarrow (x-3)^2+(y-2)^2=4](https://tex.z-dn.net/?f=%5CRightarrow%20%28x-3%29%5E2%2B%28y-2%29%5E2%3D2%5E2%5C%5C%5CRightarrow%20%28x-3%29%5E2%2B%28y-2%29%5E2%3D4)
for second circle center is at (0,-1) and radius is 3 units
Equation is given by
![\Rightarrow (x-0)^2+(y+1)^2=3^2\\\Rightarrow (x-0)^2+(y+1)^2=9](https://tex.z-dn.net/?f=%5CRightarrow%20%28x-0%29%5E2%2B%28y%2B1%29%5E2%3D3%5E2%5C%5C%5CRightarrow%20%28x-0%29%5E2%2B%28y%2B1%29%5E2%3D9)
Answer:
77) YES , 78) YES , 79) NO , 80) YES
Step-by-step explanation:
77) 12/4=3 and 18/6=3 so YES
78) 30/6=5 and 40/8=5 so YES
79) 36/25=1.44 and 48/40=1.2 so NO
80) 15/5=3 and 13.8/4.6=3 so YES
