Answer:
x=2, y=6
Step-by-step explanation:
y=10-2x
x=y-4
substitute x
y=10-2(y-4)
y=10-2y+8
Add 2y to each side
3y=10+8=18
y=6
x=y-4
x=6-4=2
x=2
Answer:
Step-by-step explanation:
The first one is actually 0 I think. The instantaneous ROC at x=1 should also be 0. The last one should be correct.
Basically, the ROC for the first one is 0 because the y value at the start and end of the interval is the same, so the change is the same. However, for the instantaneous ROC at x = 0, you look at the graph and realize that if you find the derivative at that point, it is 0.
