20 POINTS!!!
1 answer:
Try graphing using the x-intercept and y-intercept.
-15x - 5y = 45
Put in x = 0 to get -5y = 45, making y = -9. Point (0, -9) is on the line.
Put in y = 0 to get -15x = 45, making x = -3. Point (-3, 0) is on the line.
-2x + 6y = 6
Put in x = 0 to get 6y = 6, making y = 1. Point (0, 1) is on the line.
Put in y = 0 to get -2x = 6, making x = -3. Point (-3, 0) is on the line.
(We've actually stumbled on the solution since (-3, 0) is on both lines!)
Graph the two lines using the points found above.
The solution is x = -3, y = 0.

<h3>What is circle?</h3>A circle is a closed two-dimensional figure in which the set of all the points in the plane is equidistant from a given point called “centre”. The perimeter around the circle is known as the circumference.
Given that:
radius of a circular path is 7m.
Rate = Rs .35 per meter
We know that
Circumference of circle =
Circumference of circle=43.98 m
Now,
Cost = Circumference × Rate
Cost =43.98× 35
Cost = Rs 1539.38
Therefore, the cost of fencing the path is Rs 1539.38.
