Answer:
True
Step-by-step explanation:
In mathematics, a conic section (or just conic) is a curve obtained by intersecting a cone (more precisely, a right circular conical surface) with a plane. The point line and pair of intersecting lines are special types of conic sections.
 
        
             
        
        
        
3x+12=39
Minors 12 on both side
3x=27
Divide 3 on both side
X=9
        
             
        
        
        
A multiplicative inverse is the same thing as a reciprocal, which is basically just flipping the fraction and changing the sign. Therefore the multiplicative inverse of -1/9 is 9
        
                    
             
        
        
        
Step-by-step explanation:
3x + 10 < 3
3x + 7 < 0
3x < -7
x < -7/3 = -2.3333...
or
2x - 5 >= 5
2x >= 10
x >= 5
x < -7/3 or x >= 5
