Clothing Online An online clothing company sells custom sweatshirts. The company charges $2.50 for shipping plus $6.50 for each sweatshirt. Write a linear function rule that models the total cost y (in
dollars) for any number of sweatshirts x.

Multiply. −2x(6x4−7x2+x−5) express the answer in standard form. enter your answer in the box.

What is the multiplicative rate of change of the exponential function shown on the graph?

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?
