Corey and Joseph were standing next to each other in the backyard when Joseph challenged Corey to guess how tall he was. Corey knew his own height is 6 feet and when they measured their shadows, Corey's shadow was 14.5 feet long and Joseph's was 10.15 feet long. What is Joseph's height?

Answer is in the photo. I couldn't attach it here, but uploaded it to a file hosting. link below! Good Luck!

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.

step-by-step explanation:

i'm sorry mate, but i am not seeing any figures. i am unable to solve this for you.
