Equation of a circle in standard form:
(x-h)²+(y-k)²=r²
r=radius
(h,k) is the center.
In this case:
(h,k) =(0,0) (h=0,k=0 )
r=4
Therefore:
(x-0)²+(y-0)²=4²
x²+y²=16
Answer: x²+y²=16
First you have to find the slope, the slope formula is m = y2 - y1/ x2 - x1
m = y2 - y1/ x2 - x1 (-3, 8) (7, 6)
m = 6 - 8/ 7 - (-3)
m = -2/10
m = -1/5
point-slope formula;
y - y1 = m(x - x1) m = -1/5 (-3, 8)
y - 8 = -1/5(x - (-3)
y - 8 = -1/5(x + 3)
so the answer is, B.

Answer:
B
Step-by-step explanation:
I'm pretty sure that the shaded space represents all possible solutions, meaning that the X has to be greater than or equal to 2.

-8x+2=-7x+10
-x+2=10
-x=8
x=-8
