Answer:
y = -x + 1
Step-by-step explanation:
The slope-intercept formula is y = mx + b where m is the slope and b is the y-intercept. Since slope is...
this means that the slope of the line is -1 (the rise is -1, the run is 1, -1/1 = -1). By looking at the graph you can also see that the line goes through 1 on the y-axis, so the y-intercept is 1. By plugging in the appropriate values, the equation of the line is y = -1x + 1 or just y = -x + 1
Answer:
8(15-m)
Step-by-step explanation:
By looking at the options, we can understand that the right one is 8(15-m), since we need to multiply the time by the number of question.
Also, we can check that result by arranging an equations usint the total time.
55 = 3m - 8(15-m)
55 = 3m - 120 + 8m
55 = 11m - 120
55 + 120 = 11m
175 = 11m
m = 175/11 = 15.91
55 = 3*15.91 - 8(15-15.91) = 47.73 - 120 + 127.28 = 55.01 ≈ 55
694,891 - 35,427 rounded to the nearest ten thousand is 614,000.
Answer:
8/21
I don't think that it can be simplified further....
