Joe purchased a tray of 48 petunias to plant in his garden. the graph shows points representing the number of flowers left to plant at several different times while joe is planting.

select from the drop-down menus to complete the equation, in standard form, that represents the relationship between the number of petunias left to plant, y, and the time, x, joe has spent planting.

(choose) x + y = (choose)

Achemist has 200 ml of a 10% sucrose solution. she adds x ml of a 40% sucrose solution. the percent concentration, y, of the final mixture is given by the rational function: the chemist needs the concentration of the final mixture to be 30%. how many milliliters of the 40% solution should she add to the 10% solution to get this concentration?

Is it true or false i’m trying to pass this test so i can leave school
