Answer: Top-Left straight line

Step-by-step explanation:

A function on a graph is a line that does not overlap itself where two coordinates on the x-axis would be the same. All of the graphs except the top left one, are curved to where there would be two of the same coordinates for x. Also, a function is where each input (x) has only one output (y). Since the x coordinate is listed twice with DIFFERENT outputs, it cannot be a function.

pantera1 [17]

Answer: 5/36

Step-by-step explanation: We know that A U B means all the possible combinations that make event A or event B true. As we know, the only combinations that can make 4 is 1+3, 2+2, or 3+1, and the only combinations that can maker 11 is 5+6 and 6+5. This leaves us with a total of 5 combinations, and with a total of 36 combinations, that means that there is a 5/36 chance that the combinations of the dice add to either 4 or 11.

Circumference = 18.84

Solution for the radius of a circle of radius 3 . I'm sorry if I made a mistake, I am not sure of the solution.

But is there a fee for the question?

These two laws can help you in the question:

Circumference = π× diameter of the circle. Circumference = 2×π× radius

2/8 will simplify

Divide the top and bottom by 2

12/8 = 1/4

1/4*7

7/4

We need to change this from an improper fraction to a mixed number

4 goes into 7  once with 3 left over
