• She returns an item to get $15 back at one store.
She buys an item for $15 at another store.
Which is a correct description of the two quantities that represent these transactions?
A The quantities have the same magnitude, but different signs.
B
The quantities have the same sign, but different magnitudes,
с
The quantities have different magnitudes and different signs.
D
The quantities have both the same magnitude and the same sign.

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.

step-by-step explanation:

sas (side angle side)

aa (angle angle)

sss(side side side)

sas find two sides with an angle in between

aa is finding two angles and the third will add up to 180

sss find all sides

false : it can not go to 9 the highest that part can go is 7

here is your proof
