What is a synthetic material made of?

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

Solve the equation 1. x-3/4=2 4/52. -1/3x-11= -20 3. -12+5/7x= -19

Which graph represents the same relation as the table below? x f(x) –2 5 0 1 1 –1 2 –3
