The points C, D,E and F all lie on the same line segment, in that order, such that the ratio of CD:DE:EF is equal to 1:6:3. If CF=20, find EF

Show that 1-6 + 3 1 = 3 . solution: 1-6 -t 3 1 = 1-3 1 = 3 .

the circle graph is not a function.

step-by-step explanation:

the graph of the circle is not a function.

because for a graph to be a function, each value of x must give one value of y

in the circle, the values of x for -2< x< 2 each give 2 values of y.

hence this is not a function.
