Jailene is mixing marshmallows and Rice Krispies to make Rice Krispy
treats. The number of cups of
marshmallows, m, needed for r
cups of Rice Krispy r is described by
the equation r= 1.5m.
How many cups of marshmallows
are needed to mix with 3 cups of
Rice Krispies?

m = 2

Step-by-step explanation:

The number of cups of  marshmallows, m, needed for r  cups of Rice Krispy r is described by  the equation :

r= 1.5m ...(1)

We need to find the no. of marshmallows  are needed to mix with 3 cups of  Rice Krispies.

Pu r = 3 in equatin (1) :

So, there are 2 cups of marshmallows .

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.
