The amount of bacteria, fix), observed by a research scientist is represented by the function
f(x) = 3% + 7, where x is the number of hours passed since initial observation.
Which statement best compares the mathematical and reasonable ranges for this function?

Jabari is power washing houses for a summer job. for every job, he charges an initial fee plus $30 for each hour of work. his total fee for a 4 -hour job, for instance, is $170 . jabari's total fee, f, for a single job is a function of the number, t, of hours it takes him to complete the job. write the function's formula.

Two angles are complementary. the large angle is 36 more than the smaller angle. what is the measure of the large angle?

Choose the equation below that represents the line that passes through the point (2, 4) and has a slope of 3. a) y − 4 = 3(x − 2) b) y − 2 = 3(x − 4) c) y + 4 = 3(x + 2) d) y + 2 = 3(x + 4)
