One possible answer is 171 ÷ 19 = 9
Answer:
None of the equations given is the equation of the function. The correct equation is: 
Step-by-step explanation:
First we must find the slope of the line that passes through these points.
The slope between two points
and
is given by:

where
is the slope
In this case since we have the points:
and 

and the slope will be:

and now we have the slope we use the slope-point equation:

w = 2l-7
2 (2l-7+l)=43,6
3l-7=21,8
3l=28,8l=9,6
w=2.9,6-7=12,2
Area=9,6.12,2=117,12
Answer:
the decimal value for cos x is 1
