Answer:
the coefficient is 12
Step-by-step:a numerical or constant quantity placed before and multiplying the variable in an algebraic expression  explanation:
 
        
             
        
        
        
Answer:
w-6b+4/6
Step-by-step explanation:
To get the answer you have to first open the bracket which will give you w=6a+6b-4.You then take 6b-4 to the other side to meet w after this divide all by 6 to make a the subject of the formula.
 
        
             
        
        
        
Graph the parabola using the direction, vertex, focus, and axis of symmetry.
Direction: Opens Up
Vertex: <span>(−<span>5/8</span>,−<span>41/16</span>)</span>
Focus: <span>(−<span>5/8</span>,−<span>5/2</span>)</span>

It invalidates his hypothesis because it is possible for the time a trip takes to depend on the distance that is traveled during the trip.
Option C is the right answer.
The missing graph has been attached with the answer.
<h3>What is a Scatter Plot ?</h3>
These are Cartesian Points and it represents relationship between two variables.
It is given that 
Will's Hypothesis is time can never be a dependent variable.
Although from the graph plotted it can be seen that the time is dependent on distance travelled and
the in a scatter plot , the dependent variable is plotted on y axis and here the time is plotted on y axis , 
therefore the scatter plot invalidate Willis’s hypothesis.
It invalidates his hypothesis because it is possible for the time a trip takes to depend on the distance that is traveled during the trip.
Option C is the right answer.
