Answer:
width = 150 yards
length = 200 yards
Step-by-step explanation:
Using the information given to us, we can make the following two equations:
2L + 2W = 700
L = W + 50
where L is the length in yards and W is the width in yards. This could treat these two equations as a system of linear equations. There are multiple ways to solve a system of linear equations, but I am going to solve this by substitution. Before doing that, I am first going to simplify the first equation, as it will make solving the system easier.
2L + 2W = 700
Divide both sides by 2.
L + W = 350
Since L = W + 50, we can substitute W + 50 for L in the equation L + W = 700.
(W + 50) + W = 350
2W + 50 = 350
2W = 300
W = 150
Now that we found what W is, we can solve for L by plugging 150 into either one of the equations. I am going to plug it into the equation L = W + 50.
L = 150 + 50
L = 200
Now we found what L is. So now we know that the width is 150 yards and the length is 200 yards.
I hope you find my answer and explanation helpful. Happy studying. :)

Answer:
The graph in the attached figure
Step-by-step explanation:
we know 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 <u><em>and the line passes through the origin</em></u>
In this problem the given line represent a proportional relationship, because passes through the origin
we have
---> the constant of proportionality k is equal to the slope
substitute
The linear equation is
To draw a line we need two points
we have (0,0)
To find the other point
assume x=3 and substitute in the equation to solve for y
so
The other point is (3,4)
using a graphing tool
Plot the points (0,0) and (3,4)
To graph the line join the points
see the attached figure
