Work out the length of EA in the diagram below

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?

Plot the points (0,6), (3,15.8), and (9.5,0) using the graphing tool, and find the function

One integer is 5 more than another. their product is 104. find the integers
