An appliance repair person charges $55 per trip plus $15 per hour for her labor. the cost of fixing a stove was $92.50. write and solve an equation to find how many hours it took to repair the stove.

15x + 55

92.50 - 55 = 37.5

37.5 divided by 15 = 2.5

She worked for 2.5 hours and added the $55 charge.

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)
