Inez is saving money to buy a dress for the homecoming dance. The dress costs $345. She has
saved $57 and each week she adds $12 to her savings. How many weeks will it take her to save
enough money to buy the dress?
.there can be infinite values of m and n that can satisfy the above equation. for each value of m of m or n. there maybe infinite sets of solution for the above
step-by-step explanation:
step-by-step explanation:
the true statements are:
r = set of real numbers
n = set of natural numbers, 1,2,
w = n u{0} = {0,1,}
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.
