If 30 is 50% of a value, what is that value?
A.
15
B.
60
C.
90
D.
50

Proportion: 30 / x = 50 / 100

Cross-Multiply: 50x = 300

Divide: x = 60

The correct answer is B. 60.

Hope this helps!! :)

y=mx+b

step-by-step explanation:

m slope

b y-intercept

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.
