Afigure skater needs a total score of at least 90 to move on to the next round. the total score is the average of four judges scores. the first three judges scores were 83,88,and92. the figure skater made it to the next round . what is the minimum score the fourth judge could have given .

90*4 = 360

 so all the scores need to = 360 for a 90 average

83+88+92 = 263

360-263 = 97

minimum score is a 97

answer:      

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.
