Show popular fishing lake contains a combination of largemouth bass and catfish with a ratio of bass to catfish of 10 to 7. if there are 425 bass in the lake, about how many catfish are there?

Set up a proportion. If bass to catfish is 10 : 7, it must be equal to 425 : x.

7/10 = x/425 → cross multiply and solve → 10x = 7 * 425 → 10x = 2975 → x = 297.5 which is rounded to 298. There are approximately 298 catfish.

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.

step-by-step explanation:

a) 0

step-by-step explanation:

i^413 x i^0 = 0 as any number multiplied by a zero is
