Answer:
-63
Step-by-step explanation:
The opposite, or additive inverse of a number is found by changing the sign of the number. With the exception of zero, a number and its opposite (additive inverse) sum to zero.
subtract 4x from both sides and you get y=4x
y varies directly with x. When x is 1, y is 1/4. when x is 4, y is 1. when x is 8, y is 2. So on and so on. Sorry if this is confusing. Direct variations is one of my weak points
Answer:
Kayla is correct; the center is a fixed point in the middle of the sphere.
Step-by-step explanation:
Kayla is correct. Raymond is wrong because a point cannot be a radius: a radius is a line segment from the center to the surface.
The center is the fixed point in the middle of the sphere.
Answer:
(x+4)^2 + (y+3)^2 = 5^2
Step-by-step explanation:
The equation of a circle is
(x-h)^2 + (y-k)^2 = r^2
now substitute the known values
(x+4)^2 + (y+3)^2 = 5^2
and theres your equation
