Answer:
 y ≥ 3x +4
Step-by-step explanation:
The line is solid, so the inequality will include the "or equal to" case. The shading is above the line, so values of y greater than or equal to those on the line are in the solution set. The only choice with the correct (≥) inequality symbol is ...
 y ≥ 3x +4
 
        
             
        
        
        
Answer:
b.   z = 4
Step-by-step explanation:
Multiply both sides of the equation by 1/10. This gives ...
   (1/10)·10z = (1/10)·40
   z = 4                 simplified
_____
<em>Check</em>
Putting 4 where z is in the original equation should give us a true algebraic expresion. It does.
   10·4 = 40        true
