Dominic is a landscape architect and is designing a garden with an area of up to 500 square feet. he will use two types of plants: zinnias and petunias. each zinnia plant requires 1.6 square feet of ground and each petunia plant requires 1.8 square feet of ground. each zinnia plant costs $4 and each petunia plant costs $3, and the architect must spend no more than $600. let z represent the number of zinnia plants and p represent the number of petunia plants. three of the constraints for this situation are z≥0 , p≥0 , and 1.6z+1.8p≤500 . what is the other constraint for this situation? enter your answer in the boxes. __ z + __ p ≤ __

The third constraint was based on the total area that the garden can only take. Now the last constraint must be based on the total cost that should be spend in order to make a 500 square feet of garden, that is:

4 z + 3 p ≤ 600

answer: it actually depends on which is the independent variable and which is the dependent variable. let us say we're looking at a linear equation. y=2x+3. we theoretically could switch the equation to be x=(y-3)/2 and it would be the same line. so either a causes b or it can be that b causes a. so technically the answer is false

step-by-step explanation:

answer: 8 years

step-by-step explanation:

the explanation is that in 8 years the child will be 20 and in 8 years the father will be 40 and 20 is half of 40.
