Bernard solved the equation 5x+(-4)= 6x+4 using algebra tiles. Which explains why Bernard a
to both sides in the first step of the solution?
He wanted to create zero pairs on the left side of the equation to get a positive coefficient
He wanted to combine more negativelifes with the 4 negative tiles on the left side of the e
the larger coefficient on the left side of the equation.

Two lines that do not intersect are skew. always sometimes or never

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
