Round the following numbers to the nearest 10 and 100: 430 235 675 7876

430= 430 and 400 235= 240 and 200 675= 680 and 700 7876=7880 and 7900

Step-by-step explanation:

when rounding to the nearest ten, look at ones place, when rounding to the nearest hundred, look at tens place

5 or more raise the score, 4 or less let it rest. This tells you whether to round up or round down.

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.
