Answer:
Step-by-step explanation:
Let
p ----> the price of a watermelon in dollars
w ---> the weight of a watermelon in pounds
In this problem we have a proportional relationship
Remember that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form
or
In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin
In this problem
The value of the constant of proportionality k is the same that the unit rate
Find out the unit rate
Divide the total cost by the total weight
![k=\frac{4.38}{7.3}=\$0.60\ per\ pound](https://tex.z-dn.net/?f=k%3D%5Cfrac%7B4.38%7D%7B7.3%7D%3D%5C%240.60%5C%20per%5C%20pound)
substitute in the equation
Answer:
Bottom left
< means that it's dashed line
Yes it is correct. You plotted the slope and initial rate value correctly and found the
point of intersection.
Answer:
60 feet of fencing
Step-by-step explanation:
Let x feet be the width of the garden plot, then 2x feet is the length of the garden plot.
The area of the garden plot is
![A=x\cdot 2x\\ \\200=2x^2\\ \\100=x^2\\ \\x=10\ feet\\ \\2x=20\ feet](https://tex.z-dn.net/?f=A%3Dx%5Ccdot%202x%5C%5C%20%5C%5C200%3D2x%5E2%5C%5C%20%5C%5C100%3Dx%5E2%5C%5C%20%5C%5Cx%3D10%5C%20feet%5C%5C%20%5C%5C2x%3D20%5C%20feet)
Find the perimeter of the rectangular garden plot:
![P=x+2x+x+2x\\ \\=10+20+10+20\\ \\=60\ feet](https://tex.z-dn.net/?f=P%3Dx%2B2x%2Bx%2B2x%5C%5C%20%5C%5C%3D10%2B20%2B10%2B20%5C%5C%20%5C%5C%3D60%5C%20feet)
