If you get 17 out of 20 questions correct on your next test, what percent of the test you answer incorrectly?

85%

Step-by-step explanation:

You can use proportions to solve this answer.

17/20=x/100

Solve for X

17(100)/20=x

85=x

15% incorrect

Step-by-step explanation:

17/20 = x/100

17 ×5= 85

20×5 = 100

85/100 correct

15/100 incorrect

17 1/3

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.
