How do you multiply

(2) (- 4) (2) (3) (- 2) (2)

https://socratic.org/questions/how-do-you-multiply-2-4-2-3-2-2

Multiply the absolute numbers and then multiply the signals: +192 Explanation:

(2) (- 4) (2) (3) (- 2) (2) = (- -) 2 \times 4 \times 2 \times 3 \times 4 \times 2 \times 2

What is the slope of the line passing through the following points:

(- 2, - 7), (- 3, 0)

https://socratic.org/questions/what-is-the-slope-of-the-line-passing-through-the-following-points-2-7-3-0

- 7

\frac{0 - ( - 7 )}{- 3 - ( - 2 )} = \frac{7}{- 1} = - 7

What is the slope of the line passing through the following points:

(- 2, - 7), (- 1, 1)

https://socratic.org/questions/what-is-the-slope-of-the-line-passing-through-the-following-points-2-7-1-1

The slope is 9. Explanation: This is the equation we're going to use:

\frac{y _{2} - y _{1}}{x _{2} - x _{1}}

Let's do some simple substitution and solve:

\frac{1 - - 7}{- 1 - - 2} = \frac{1 + 7}{- 1 + 2} = \frac{8}{1} = 8

What is the slope of the line passing through the following points:

(3, - 1), (- 4, 5)

https://socratic.org/questions/what-is-the-slope-of-the-line-passing-through-the-following-points-3-1-4-5

The slope of the line passing through the two points is

- \frac{6}{7}

. Explanation: Use the slope formula:

m = \frac{y _{2} - y _{1}}{x _{2} - x _{1}}

What is the equation of those tangent planes to the sphere

x^{2} + y^{2} + z^{2} + 2 x - 4 y + 6 z - 7 = 0

which intersect the line

6 x - 3 y - 23 = 0

https://socratic.org/questions/what-is-the-equation-of-those-tangent-planes-to-the-sphere-x-2-y-2-z-2-2x-4y-6z-

See below. Explanation: Given a line

L \to p = p_{1} + λ v

Π \to ⟨ p - p_{1}, n ⟩ = 0

L \in Π \Rightarrow λ ⟨ v, n ⟩ = 0
