There were three quizzes for the week. the first quiz was worth twice as much as the second quiz. the third quiz was 10 points less than the second quiz. the total points for the quizzes that week were 70 points. how much was each quiz worth.

x^6

step-by-step explanation:

this is correct because:

x-6=0

0*x=0

so

x^6

1/4 because there is 4 grades.

what graph

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.
