Answer:
Minimum value occurs at (x, y) = (-5,0)
Step-by-step explanation:
Given: 3x + y =15
Rewriting this equation to Slope - Intercept form, we get:
y = -3x + 15
Squaring both sides,


Substituting in
we get:

= 
Comparing this equation with
we get
and
.
The minimum value occurs at the axis of symmetry given by
.
Therefore, x = - 

If x = 5, y = -3(5) + 15 = 0
Thus, the point becomes (5,0) where it is minimum.
It will take him 8 hours to get there.

Answer:
b^5
Step-by-step explanation:
b^ -6 * b^11
We know that a^c * a^d = a^ (c+d)
b^ -6 * b^11 = b^(-6+11)
= b^(5)
