Could someone please help me with this question?

4 bags

Step-by-step explanation:

To find the area of the ring, we need to find the area of both the ring AND the garden, and subtract the area of the garden, so our equation will look like this:

So the area of the ring is about 18.84 square yards

If the bags of sand can cover 5 square yards, then we can divide 18.84 by 5 to figure out how many bags we need.

After dividing we find that we need 3 whole bags and about half of a fourth, so the gardener should buy 4 bags of sand

y = - 6

step-by-step explanation:

given the point (- 2, y) lies on the graph then it is a solution of it's equation.

substitute x = - 2 into the equation for value of y

y = 3(- 2) = 3 × - 2 = - 6

the point on the graph is (- 2, 6)
