Step-by-step explanation:
The slope is often called "rise over run" because it measures the difference in y-values divided by the difference in x-values:
slope (m) = (y2-y1) / (x2-x1)
slope = (4-1) / ((-6)-0)
slope = 3/(-6)
slope = -1/2 [divide numerator and denominator by (-3)]

Use a variable (x) for the smallest angle (call it angle 1). Angle 1 = x The second angle is twice the smallest angle (2x) The largest angle is 6 times the smallest angle (6x) Take the sum of all three of those angles and make an equation, equal to 180. x + 2x + 6x = 180 9x = 180 (combined like terms) x = 20 (divide by 6) Angle 1 (x) = 20 Angle 2 (2x) = 40 Angle 3 (6x) = 120
Answer:
4.5 seconds
Step-by-step explanation:
The difference means subtraction.
So, we just subtract 33.9 from 38.4 to find the difference:
38.4 - 33.9
4.5
The difference is 4.5 seconds
