Create an equivalent system of equations using the sum of the system and the first eguation,
-5x + 4y - 8
4Xy - 2
5x + 4y = 8
9x + 5y 10
-5x + 4y = 8
X + 5y 10
5x + 4y = 8
9x + 5y = 2
-5x + 4y = 8
--x + y + 10

answer: 15

step-by-step explanation:

21/58.

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)
