A store sells mugs each mug cost the same amount during a sale the store reduces the price of each mug by $1.25 Jackson Spends $11.48 on 2 mugs at the sale price what is the price of one mug before the sale

You're question is really hard to read so I don't know if this is right but this is what I did:

2 mugs = $11.48

1 mug (after sale) = $11.48 / 2 = $5.17

1 mug (before sale) = $5.17 + $1.25 = $6.99

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:

the answer is b
