The Pen-Ink Company manufactures two ballpoint pens: silver and gold. The silver requires 9 minutes in a grinder and 7 minutes in a bonder. The gold
requires 11 minutes in a grinder and 5 minutes in a bonder. The grinder can be
run no more than 370 minutes per day and the bonder no more than 200
minutes per day. Let x represent the number of silver pens, and let y represent
the number of gold pens. Find the system of inequalities that represents this
company's daily production of silver and gold pens. DO NOT SOLVE.

Marco is studying a type of mold that grows at a fast rate. he created the function f(x) = 345(1.30)x to model the number of mold spores per week. what does the 1.30 represent? how many mold spores are there after 4 weeks? round your answer to the nearest whole number. 1.30 represents the number of mold spores marco had at the beginning of the study; 985 mold spores 1.30 represents the number of mold spores grown in a given week; 448 mold spores 1.30 represents the 30% rate of weekly growth; 345 mold spores 1.30 represents the 30% rate of weekly growth; 985 mold spores

The domain of a function can be represented by which one of the following options? o a. a set of output values o b. a set of f(x) values o c. a set of input values o d. a set of both input and output values

Use the quadratic function to predict f(x) if x equals 8. f(x) = 25x2 − 28x + 585
