Answer:
1. A is d=1.75
Step-by-step explanation:
Standard form of a circle" (x-h)²+(y-k)²=r², (h,k) being the center, r being the radius.
in this case, h=-2, k=6, (x+2)²+(y-6)²=r²
use the point (-2,10) to find r: (-2+2)²+(10-6)²=r², r=4
so the equation of the circle is: (x+2)²+(y-6)²=4²
No I do not know how to do this
Answer:
It will go 400 kilometers in 5 hours and 800 kilometers in 10 hours
Step-by-step explanation:
80*5= 400 (in 5 hours)
80*10=800 (in 10 hours)
Answer:y=2x+1
I believe. I could be wrong. But I think im right
Step-by-step explanation:
2x-y=-1
-2x -2x
(-1)-y=-1-2x(-1)
y=2x+1
