Can someone please help? The Girl Scouts sold 4 boxes of sugar cookies to strangers and 124 boxes to relatives (all at the same time) If she sold $320 worth of sugar cookies in total, what was the price of each box?

$2 dollars and 50c

Step-by-step explanation:

124 + 4 equals 128 and 320 divided by 128 is 2.5, so 2 dollars and 50 cents.

correct answer:

b.(19,-2)

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.
