Noah is buying a pair of jeans and using a coupon for 10% off. The total price is $56.70, which includes $2.70 in sales tax. Here are some equations that are related to$$x−0.1x+2.70=56.70. Each equation is a result of performing one or more moves on that original equation. Each can also be interpreted in terms of Noah’s purchase. For each equation, determine either what move was made or how the equation could be interpreted. (Some examples are given here.)

answer: 20

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.
