Anna is preparing the soil in her garden for planting tomatoes. The directions say to use 4 pounds of fertilizer forb120 square feet of soil. The area of Anna's garden is 180 square feet. How much fertilizer is needed for a 180 square-foot garden?

6 pounds of fertilizers are needed for garden area of 180 square foot.

Step-by-step explanation:

Let 'x' pounds of fertilizers be needed for 180 square foot garden.

Given:

4 pounds of fertilizer needed for an area of 120 square foot.

The area of the garden given is 180 square foot.

Now, as per question:

4 pounds of fertilizer is equivalent to an area of 120 square foot.

Therefore, 'x' pounds of fertilizer is equivalent to an area of 180 square foot.

Applying proportion and cross multiplying method, we get:

Therefore, 6 pounds of fertilizers are needed for garden area of 180 square foot.

x=-2

infinite number of lines, so there is an infinite number of equations.

step-by-step explanation:

there are an infinite number of line that passes through the point (-2,5)

x=-2   is one line that passes through the point

y = 5 is another line that passes through the point

(these two lines are perpendicular to each other).

since the number of   numbers are infinite and the slope is the ratio of two numbers,(change in y over change in x) we can have an infinite number of slopes.     our only condition is that it passes through the point (-2,5)
