Type the correct answer in each box. Joan is hiking. She wants to cover 1,600 feet. She hikes 600 feet every 3 hours.

The equation of the line that models y, the distance left to hike, after hiking for x hours is y =

200

x +

1600

. It will take Joan

8

hours to hike 1,600 feet.

Is it negitive or positive 200?

b

step-by-step explanation:

guess at question:

a vertical line intersects the graph of g(x,y) = 0 at two points. what conclusion follows about the function f(x) implicitly defined by g(x,f(x)) = 0?

the domain of f(x) cannot include the x coordinate of any such vertical line.

informally, f(x) is not a function, and

g(x,y)=0 cannot be solved for y uniquely.

the relation r = {(x,y) such that g(x,y) = 0} is a function if

for all (a,b) ∊ r and (c,d) ∊ r, a=c implies b=d.
