Anna is preparing the soil in her garden for planting tomatoes. The directions say to use 4 pounds of fertilizer for 120msquare feet of soil. How much fertilizer is needed for a 180 square-foot garden

6 pounds of fertilizer.

Step-by-step explanation:

We can solve this problem using rule of three:

Anna needs to use 4 pounds of fertilizer for each 120 square feet of soil. With that values, we make the first fraction: 4/120

Now, she needs X pounds of fertilizer for 180 square feet of soil. The fraction now is X/180

Then, we need to make the first fraction equal to the second, and then find the value of X:

4/120 = X/180

X = 4*180/120 = 6

So Anna will need 6 pounds of fertilizer.

Another way to solve this problem is calculating the amount of soil for one pound of fertilizer:

If 4 pounds of fertilizer is necessary for 120 square feet of soil, 1 pound is necessary for 120/4 = 30 square feet of soil.

If we have 180 square feet of soil, we divide 180 by 30 to find the amount of fertilizer necessary:

180/30 = 6 pounds of fertilizer.

step-by-step explanation:

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.
