First, let us break down 28 hours 36 minutes into minutes.

Number of minutes taken to grade 220 essays = (28 x 60) + 36 = 1680 + 36 = 1716 minutes

Now, we can find the average time taken to grade an essay by dividing the time taken to grade 220 essays by 220.

Average amount of time taken to grade an essay = \frac{1716}{220} = 7.8 minutes, or 7 minutes and 48 seconds

Margarita [4]

Answer:

x = 1

Step-by-step explanation:

The line 1 passing  through the points (-2,4), (0,2) and (1,1) is represented by the function f(x).

Again the line 2 is represented by y = g(x) and it passes through the points (-3,-3), (0,0) and (1,1).

So the only common point between line 1 and line 2 is (1,1) and it will be unique since two straight lines meet at only one point if they are not parallel.

Hence, for x = 1 input value produces the same output value y = 1 for the two functions f(x) and g(x) on the graph. (Answer)
