-4x > 8
Divide by -4:
x < -2
-4x + 7 > 15
-4x > 8
Divide by -4:
x < -2
Answer:
Step-by-step explanation:
The standard equation of a circle is given by:
Where (<em>h, k</em>) is the center and <em>r</em> is the radius.
We are given that the center is (4, -7) and that the radius is √(43).
So, <em>h</em> = 4, <em>k</em> = -7, and <em>r</em> = √(43). Substitute:
Simplify. Hence, our equation is:
