So hmmm check the picture below
so, we're looking for dr/dt then at 4:00pm or 4 hours later
now, keep in mind that, the distance "x", is not changing, is constant whilst "y" and "r" are moving, that simply means when taking the derivative, that goes to 0
Slope = (-5 - (-3))/(3 - 1) = -2/2 = -1
Answer:
14
Step-by-step explanation:
Let x = 1. Substitute x = 1 into the equation:
y = -9X(1)+3
y = -9+3
y = -6
-> Ordered pairs are written in the form (x,y). Thus in this case, your ordered pair is (1,-6).
