Which function represents the equation of the line? a. f(x)= -x-4 b. f(x)= -x+4 c. f(x)= x-4 d. f(x)= x+4

Since the line goes from bottom left to top right, the slope is positive. So, the answer is either C or D.

Moreover, the function passes through [/tex] (0,-4) [/tex], which means that the answer is C. In fact, you have

We can solve this in many ways, let's try this one.

T∧2 = 4 pi∧2 * a∧3 / GM    First we will multiply whole equation with variable( or parameter) M and get

M * T∧2 = 4 pi∧2 * a∧3 / G  After that we will divide whole equation with variable ( or parameter )  T∧2 and get

M = 4 pi∧2 * a∧3 / G * T∧2

This is correct answer

Good luck!!!
