All you have to do is divide 20 by 12.5
Step-by-step explanation:
Let x be the length and y be the width of the rectangular plot.
The plot is bounded on one side by a river and on the other three sides by a single-strand electric fence. It means,
x+2y = 1500
x = 1500 - 2y ....(1)
We know that the area of a rectangular plot is given by :
A = xy ....(2)
Put the value of x from equation (1) in (2)
.....(3)
For largest area, differentiate above area equation wrt y.

Put the value of y in equation (1).
x = 1500-2(375)
= 750 m
Put the value of y in equation (3).

Hence, the largest area is 281250 m² and its dimensions are 750 m and 375 m.

Answer:
y=120x
Step-by-step explanation:
You can just divide all of the points (y/x) and they all equal to 120. And when you add it to the equation its y=120x
Answer:
Equation of a line is y = mx + c
where
m = slope
c = y intercept
y = 1/6x - 3
Comparing with the above formula
m = 1/6
Since the lines are parallel their slope are also the same
So the equation of the line using point (-4,2) is
y - 2 = 1/6( x + 4)
y - 2 = 1/6x + 2/3
y = 1/6x + 2/3 + 2
y = 1/6x + 8/3
Hope this helps
