One rectangle is 12 in by 10 in The second rectangle is 8 in by (X)
Using the similar shape concept, what is the missing value (x)?

12/10 = 8/x

12x=80

x=6.666666

x=7

Step-by-step explanation:

6.666667

Step-by-step explanation:

We can use a proportion to solve this problem:

12 : 8 = 10 : x

x = (8 * 10)/12 = 6.666667

answer: what

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.
