For this case we have that by definition, the law of the signs of multiplication states that:

$+ * + = +\\+ * - = -\\- * + = -\\- * - = +$

So:

Option A:

$- * - * + = + * + = +$

It does not give a negative sign.

Option B:

$+ * - * - = - * - = +$

It does not give a negative sign.

Option C:

$+ * + * + = + * + = +$

It does not give a negative sign.

Option D:

$- * - * - = + * - = -$

The sign is negative.

Answer:

Option D

Answer:

L = 7 W= 12

Step-by-step explanation:

Ok so we already know that a rectangle is not even so the numbers will have to be 2 diff numbers.

The length is 5 feet less then width

w*l= 84

1* 84 2* 41 3*28 4*21 6*14 7*12

84-1 41-2 28-3 21-4 14-6 12-7

83 39 25 19 8 5

So,

your equation would be l*w = 7*12

Find the coordinates of the other endpoint of the segment, given its midpoint and one endpoint. (Hint: Let (x,y) be the unkno

spin [16.1K]

The other endpoint is (1, -17).

The midpoint formula is:

$m=(\frac{x_1+x_2}{2}, \frac{y_1+y_2}{2})$

Using our midpoint and endpoint, we have:
$(6, -11) = (\frac{11+x_2}{2}, \frac{-5+y_2}{2})
\\
\\6=\frac{11+x_2}{2} \text{ and } -11=\frac{-5+y_2}{2}
$

For the first equation (to find the x-coordinate) we will multiply both sides by 2:
$6\times2=\frac{11+x_2}{2}\times 2
\\
\\12=11+x_2$

Subtract 11 from both sides:
12 - 11 = 11+x₂ - 11
1 = x₂

For the second equation (the y-coordinate) we multiply both sides by 2:
$-11\times2=\frac{-5+y_2}{2}\times 2
\\
\\-22=-5+y_2$

Add 5 to both sides:
-22+5 = -5+y₂ + 5
-17 = y₂

This means that (x₂, y₂) is at (1, -17).

Compute: 245 * 1,493. Show your work.

sesenic [268]

0 + 0 + 5 = 5

0 + 2 + 6 = 8

6 + 7 + 4 = 17
Put the 7 in the appropriate column and carry the 1.

8 + 9 + 7 + 1(carried) = 25
Put the 5 in the appropriate column and carry the 2.

9 + 5 + 2(carried) = 16
Put the 6 in the appropriate column and carry the 1.

2 + 1(carried) = 3

So: 1493 × 245 = 365785

Studentka2010 [4]

Answer: The third one

Step-by-step explanation: We can eliminate the first one right off the bat sinc we see that -4 has two outputs. Next, the graph's equation has no slope (x=3) so the input is all the same. Thirdly, the table shows a relationship between x and y and the numbers don't have a pattern that shows more than one output or input for a number. The fourth option are simply coordinates, it doesn't particularly tell us that all the coordinates are related to each other.
