Given f(x) and g(x) = f(x) + k, look at the graph below and determine the value of k

Step-by-step explanation:

k is the y-intercept.  In other words, the y-intercept is the point ON the y-axis where the line goes through.  Our line goes through the y-axis at 3.  So, k = 3.  The k value for f(x) is -2, right where the line goes through the y-axis.  It will always be that way for lines.

50 min

step-by-step explanation:

they will be decreasing both their times in half

60 / 2 = 30

40/2 = 20

30 + 20 = 50
