A trench needs to be at least 63 feet below ground level. This means it needs to be more than 3 1/2 times its current depth. This depth is represented by the inequality 3 1/2d < -63, where d is the current depth of the trench. Select from the drop-down to correctly interpret the solution of this inequality.

The current depth of the trench is Choose... feet below ground level.
A. At most 18
B. Deeper than 18
C. less than 18

What is the point-slope form of theequation for the line with a slope of-2 that passes through (1, 4)? a y + 1 = -2(x + 4)b y-1=-2(x-4)c y + 4 = -2(x + 1)d y - 4 = -2(x - 1)

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
