4. If 60 marks is 40%, what is full
marks?

150

Step-by-step explanation:

First of all divide the given marks with given percent and divide it by 100

60/40*100=150

Mark as Brainliest

60/x=40/100

40x=6000

40x/40=6000/40

x=6000/40

x=150 marks

i will pick c put check it over to be sure

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.
