Rebecca needs 12 3/4 yards of fabric to make a quilt. She has one piece of fabric that is 3 1/4 yards and another piece of fabric that is 3 1/4 yards. How many more yards does Rebecca need to make the quilt?

c-4 is the final answer! : )

b

step-by-step explanation:

a. she will receive a refund of $278.

step-by-step explanation:

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.
