Tres cuadrados iguales están superpuestos como indica la figura. Las áreas de las zonas superpuestas son de 2 cm2, 5 cm2 y 8 cm2, respectivamente. El área total de la zona no-superpuesta de los cuadrados es de 117 cm2. ¿Cual es la longitud del lado de cada cuadrado?

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:

you didn't post any answer choices, so its not 100% clear what your teacher is looking for

however, log(15/7) is equivalent to log(15) - log(7)

i'm using the rule log(x/y) = log(x) - log(y)

answer: translate the circles so they share a common center point and dilate circle y by a scale factor of 3.
