Answer:
y=cotx
Step-by-step explanation:
The greatest common factor between 72 and 54 is 18.
Answer:
-3/2
Step-by-step explanation:
Let x = the integer:
2x^2 - 18 = 9x
2x^2 - 9x - 18 = 0
Now either factor that or use the quadratic formula if you're lazy like me.
x = -3/2 and 6, so x must be 6 because it has to be an integer.
Both the x and y have to be greater than zero so you need to add two inequalities, x>0, y>0
