Answer:
x = 
Step-by-step explanation:
Given
A = 
xy
Multiply both sides by 2 to clear the fraction
2A = xy ( divide both sides by y )
= x
Y=200x. it will take joan 8 hours to hike 1600 ft.
Answer:
B
Step-by-step explanation:
The initial value for a function is the value of y when x=0. For function A, we can see from the table that when x = 0, we have y = 4. For function B, we plug in 0 in our equation and solve: y = 3(0) + 5, or y = 5. So, because function B has a larger value of y when x = 0, function B has the greater initial value because the initial value for Function A is 4 and the initial value for function B is 5.
