Ratio of hot to cold drinks is 2: 3 there are a total of 900. how many were hot

600

Step-by-step explanation: you multiply 3 times 300 equals 900 and you multiply 2 times 300 equals 600

Step-by-step explanation:

2x + 3x =900

5x = 900

x= 900/5

X= 180

Therefore, hot drinks equal 180*2= 360

Cold = 180*3= 540

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value

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.
