Step-by-step explanation:
when given the first set, you combine like terms so you add 5h and 3h together and -6 and 2 are combined, so the first one is 8h -4. The second set you distribute 2 to 4h and -2 getting you 8h and -4 as well
1. find the speed of a car
the distance is 124 miles and the time is 2 hours
the speed is defined as distance / time, therefore
speed = 124/2 = 62 miles/hour
that is the speed
2.find the time from equation time = distance/speed, when the distance is 395 miles and the speed is 79 miles/hour, then
time = 395 miles / 79 miles/hour = 395/79
time = 5 hours
The set A U B is represented by shading both circles A and B (also the overlapping region as well). Any point in set A U B will be in either A, B or both.
