First, we can use the points (4,3) and (20,15) to find the slope of the line:

Now we can find the relation function using the point (4,3) and the slope s=3/4

therefore, the equation to describe the relationship between J and M is m=3/4j
Beacause if it is cold-blooded it needs the sn to warm itself because it cannot with cold blood
Convert 1/4 and 3/10 to have a common denominator:
1/4 = 5/20
3/10 = 620
Now you have 2 5/20 + 4 6/20 = 6 11/20
The answer is A.
6(c-20)≤360 divide both sides by 6
c-20≤60 add 20 to both sides...
c≤80
So the original cost of chairs must be $80.00 or less.
