The slope of the perpendicular line will be the negative reciprocal of 3, the slope of the given line.
  m = -1/(3) = -1/3

Only choices C and D have this slope. Only choice D goes through the given point. (-1/3)*6 +10 = -2 +10 = 8.

The appropriate selection is ...
  D. (-1/3)x + 10

What is the product of (-4)(7) and why?
Mumz [18]

Answer:

The product of (-4)(7) is -28 because you are removing 4 times, the number 7

.

Reason is below.

Step-by-step explanation:

The number which is written first in the multiplication or the product is always multiplied by the second number.

For example

3 × 2 implies three times two which equal to 6

2 × 3 implies two times three which is also equal to 6

Therefore the number written in the first is count as times, the number second.

For example

-3 × 2 implies three times two which equal to -6

Here the product is negative 6

Because if a negative number is multiplied by positive number you will always get the product as negative number.

If a positive numbers multiplied by positive number you will always get the product as a positive number.

For example

3 × 2 implies three times two which equal to 6

If a positive numbers multiplied by negative number you will always get the perfect as a negative number.

For example

3 × -2 implies three times two which equal to -6

If a negative number is multiplied by negative number you will always get the product as a positive number.

For example

-3 × -2 implies three times two which equal to 6

Therefore, the product of (-4)(7) is -28 because you are removing 4 times, the number 7
