Answer:
100 miles
Step-by-step explanation:
We need to read the graph to determine the answer.
The input is 10 hours
Using the x, go up until you hit the red line and read the y value
The y value is 100 miles
 
        
             
        
        
        
Answer:
16.4 units to the nearest tenth.
Step-by-step explanation:
sin 66 = 15 / x
x *  sin 66 = 15
x = 15 / sin 66
= 16.4196
 
        
             
        
        
        
D) 2.1+2x=7.5
All the sides added together will equal the perimeter
        
                    
             
        
        
        
Your slope is wrong! Your slope is going to be 3/2, or C for the first problem. Your y intercept is wrong! Your Y- intercept is actually (0, -1.3) or B for the second problem. 
Your equation is going to be 
y= 3/2x-1.3
