D = x
E = .5x
F = 2x-2
(x)+(.5x)+(2x-2)=180
3.5x-2=180
3.5x=182
x=52
F = 2(52)-2 = 102 degrees
This problem describes two points in a route of 4 hours. He went through 68 miles after the first two hours, and 132 miles after 4 hours of driving. We need to calculate the average rate of change.
The average rate of change is the division between the total distance and the time it took to travel that distance, so we have:
The average rate of change is equal to 33 miles per hour.
I think the y coordinate. Not sure
No, Louise is incorrect because using the order of pemdas I know that (5x3+3)2 is 36. I also know that (5x3)2+(3)2 is 36 using the order of pemdas. However the 3rd problem is 25x6+9 and using pemdas I know that this would equal 234 which is not equal to 36 therefore Louise is incorrect.
