Solve the inequality 14a/11>4/3, and write the solution in interval notation

The line y = x + passes through (−3, 7) and is parallel to y = 4x − 1.

Find the zeros of the function. write the smaller solution first, and the larger solution second f(x)= (x+6)^2-49

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?
