X-1+3/2x-2>1

(x-1) + 3 / (2x-2) > 1

Multiply by lcd.

(x-1) + 3 > 2x-2

(x-1) + 5 > 2x

x-1 + 5 > 2x

x + 4 > 2x

4 > x

x<4

x-1+3>2x-2

x-2x>-2+1-3

-x>-4

=x<4

Step-by-step explanation:

false

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)
