25y - 20x = 100 and 5x - 4x = 20 are? a. neither parallel nor perpendicular
b. the same line
c. parallel
d. perpendicular

(p. s I have already solved both equations, both come out to be 4/5. But, how do I identify if they're on the same line, or parallel?)​

step-by-step explanation:

if x = 2 you have to find x to finish the problem

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)
