The sine of 30° is  0.5 .
Angles don't have y-values, and neither do their sines.  But
IF you draw a graph of the sine function, AND the angles 
(the independent variable) are marked off on the x-axis of 
the graph, AND the value of the sine function of each angle 
(the dependent variable) is marked off on the y-axis of the 
graph, THEN the y-value corresponding to the angle of 30° 
would be displayed as 0.5 .

Answer:
6 weeks
Step-by-step explanation:
6*5=30
100+30=130
20*6=120
120+10=130
130=130
 
        
             
        
        
        
Yes, (3, 2) is a solution to y = 2x - 4. (:
