For the function R(x)= x+4/x-3, find the values of x that make the function less than or equal to 0

-4x<3

Step-by-step explanation:

1)Break this into 2 case, equal to 0 and and less than 0.

2)The number equals zero if its numerator is 0 which happens when x=-4.

3) A fraction is less than 0 it is negative. Negative fractions are either +/- or -/+,  so we have two subcases.

3a) For +/- the numerator is positive when x>-4 and denominator is negative when x<3. Putting those two together we have -4<x<3.

3b)For -/+ the numerator is negative when x<-4 and the denominator is positive when x>3 however those two values don't overlap.

4) Putting this together we have -4x<3

80+60+y=180

then divide the difference between 60 and y and add it to 180

so x =180 +( (y-60)/2)

x equals 200
