The slope is the ratio between the change in the y and x values. When you write a line as  , the slope is the coefficient
, the slope is the coefficient  . So, the slope of the first graph is 405, which means that the first plane flies with a speed of 405 miles per hour.
. So, the slope of the first graph is 405, which means that the first plane flies with a speed of 405 miles per hour.
Similarly, from the table we can see that each time you increase x by 1, the distance traveled increases by 435. So, the slope of the second graph is 435, which means that the second plane flies with a speed of 435 miles per hour, and is thus faster.
 
        
             
        
        
        
For this case we have by definition that the area of a parallelogram is given by:

Where:
b: It's the base
h: It's the height
According to the data we have:

Substituting in the formula:

Answer:
h(f(x)) = 2x - 11
Step-by-step explanation:
substitute for x in h (x), the values of f(x)
 h(f(x))= 2(x-7)+3
 =2x-14+3
 =2x-11
 
        
             
        
        
        
Answer:
141.3 cubic inches
Step-by-step explanation:
The volume of a cylinder is found using the volume formula  .
.
The radius is half the diameter 6 which is 3.
Substitute h=5 and r = 3.
