4.7c + 3.8 = 13.2
4.7c = 13.2 - 3.8
4.7c = 9.4
c= 9.4 / 4.7
c=2
Alrightie! So we are trying to isolate independent variables! WOO HOO!
So for a.) y = mx + b which is the point-slope formula... do this :)
y = mx + b
y - b = mx + b - b
y - b = mx


b.) follow the same way I did above, but instead of dividing x, divide by m.
c.) I = prt which is the equation for interest.
divide each side by pr.
d.) This one is like a and b. So lemme show ya.


Time taken by Julian to complete 24 km trip to Guelph at 12 km/h =
hours
Time taken by Julian for return trip at 8 km/h =
hours
As given, the total distance is 24 + 24 = 48 km.
And the total time is 2 + 3 = 5 hrs.
Hence, the average speed for the entire trip is =
The answer is 9.6 km/hour.
Step-by-step explanation:
a) 2(32-4j+8k-jk)
b)a(3a-ab+3c -bc)
c)m(2m - mn + 2n - n^2)
3.072 seconds, (38.4/12.5)
