25 dollars I think. Use a calculator if necessary.
Multiply both sides by b to get a = bc.
Answer:
y=-x-3
Step-by-step explanation:
Pick two points on the line and use the slope formula. I chose (-3,0) and (0,-3). Use the slope formula. Ur answer is -1 (slope). The equation is y=mx+b. b is the y-int. That's -3 so ur equation is y=-x-3.
Answer:
The graph in the attached figure
Step-by-step explanation:
we know that
The equation of the circle into center radius form is equal to

where
(h,k) is the center of the circle
r is the radius of the circle
In this problem we have


so
the center is the point 
the radius is 
therefore
the graph in the attached figure
Wouldn’t be 0 because that’s where the line cross the middle line
