Answer:
a
Step-by-step explanation:
Umm this should be in physics but F is proportional to 1/r^2 I am assuming you want to just take the derivative in respect to r of both sides of the equation
F = (2.99x10^16)/r^2
So you do that and you get
dF/dr = -2(2.99 * 10 ^16)/ (r^3)
is this for calc class?
Answer:
i think it is 8/125
Step-by-step explanation:

The given equation has a slope of 
. Parallel lines have the same slope.
Point-Slope formula: y - y₁ = m(x - x₁) ; where (x₁, y₁) is the point and "m" is slope
y - y₁ = m(x - x₁)
y - (-4) = (x - 2)
y + 4 = x + 
<u> - 4</u> <u> - 
</u>
y = x - <u>
