I need help on figuring out the two ways.

1 answer:

4 0

I believe the diagonals would be perpendicular. So if it's on a graph/coordinate plane the slopes would be opposite. And all the sides would be the same length/2 sets are parallel/same slope

Approximately 23. It is simple, but if you are asking because you don't know how to find it, divide the smaller number by the bigger number. Then, multiply this number by 100.

Hope I helped!

For which operations is the set {–1, 1} closed? Choose all answers that are correct. A.addition B.subtraction C.multiplication D

qaws [65]

A set is closed under an operation if performing the operation on the numbers in the set results in a number that is in the set.

Addition:
$-1+1=0 \\ -1+(-1)=-2 \\ 1+1=2$
-2, 0, 2 aren't in the set, so the set isn't closed under addition.

Subtraction:
$-1-1=-2 \\
1-(-1)=2 \\ -1-(-1)=0 \\ 1-1=0$
-2, 0, 2 aren't in the set, so the set isn't closed under subtraction.

Multiplication:
$-1 \times 1=-1 \\ -1 \times (-1)=1 \\ 1 \times 1=1$
-1 and 1 are in the set, so the set is closed under multiplication.

Division:
$\frac{-1}{1}=-1 \\
\frac{1}{-1}=-1 \\ \frac{-1}{-1}=1 \\ \frac{1}{1}=1$
-1 and 1 are in the set, so the set is closed under division.

The answers are C and D.

I don't understand how to do these probability questions, what two fractions do I multiply to get these answers?

I believe the two fractions are the numbers they all have in common.
