Answer:
When you multiply an odd number of negatives you get a negative result. When you multiply an even number of negatives you get a positive result.
First, multiply normally.
25x10x5
1100
Then determine whether the sign is positive or negative. Since there is an odd number of negatives, the sign is negative.
So, the answer is -1100.

So hmm check the picture below
a circle has a total of 360°, thus arcBC + x + arcCD is 360, so arcCD is just 360 - 112 - x, whatever "x" was that you found
Answer:
Yes
Step-by-step explanation:
-2(9)+4= -14 and -14 is equal to -14.
Answer:
x = -21/11
Step-by-step explanation:
6(2x + 4)2 = (2x + 4) + 2
12(2x +4) = 2x + 4 + 2
24x + 48 = 2x +6
22x = -42
x = -21/11
Functions cannot have different values of y for the same value of x. Now let us check each case one at a time.
<u>First Case:</u> For the same value of x=-1, y has two different values of 7 and 1, which is not allowed in a function. Therefore, the first case is not a function.
<u>Second Case:</u> For the same value of x=-1, y has two different values of -5 and 1, which is not allowed in a function. Therefore, the second case is not a function.
<u>Third Case:</u> For the same value of x=3, y has two different values of 2 and 4, which is not allowed in a function. Therefore, third case is not a function.
<u>Fourth Case:</u> In this case no value of x is same. So, this is a function.
