How do you solve 11=t+11.5-t?

Step-by-step explanation:

11=t+11.5-t

subtract 11.5 from both sides

-.5=t-t

-.5= 0

there is no solution to this problem

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.
