17. Jo just started collecting stamps. So far he
has 12 stamps. The number of U. S. stamps,
u, is 3 less than twice the number of foreign
stamps, f. How many of each type of stamp
does Joe have ?

b. x- 48 =120

step-by-step explanation:

the answers are in the images, i received 100% on this assignment. hope this !

hey! so 1 (25) out of 4 (100) is 25 so your answer is 25%. it's like quarters!

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.
