At 2: 15 pm, the temperature of a substance in a science experiment was 7∘f. the temperature was then recorded at 15-minute intervals. at each interval, the new temperature was 3∘f less than the previous temperaturewhat was the temperature of the substance at 3: 30 pm?

The function f(x) is shown in this graph the function g(x)=6x

Find the center of the circle that can be circumscribed about efg with e(4,4) f(4,2) g(8,2)

Part 1: use the graph to count the slope of the line that passes through the points (2,1) and (2,0).part 2 in two or more complete sentences,explain why it is not possible to write the equation of the given line in the traditional version of the point-slope form of a line
