Find the solution of the system of equations.
-3 + 9y = -19
3x - 3y = 9

your answer is the frist one

hop i

what i would say the best answer is a. 40.5

m∠a is 90°

m∠b is 40°

given : the shape of his satellite can be modeled by   where x and y are modeled in inches.

now,the given equation   is a equation of parabola.

here, coefficient of x is positive, hence the parabola opens rightwards.

on comparing this equation with standard equation , we get

in standard equation, coordinates of focus=(0,m)

thus for given equation coordinates of focus=(0,1.5)
