BigorU [14]2 years ago
8 0

Step-by-step explanation:

It's the <em>DISTRIBUTIVE PROPERTY</em>:

m(a + b) = ma + mb

m\cdot(a+b)=m\cdot a+m\cdot b=ma+mb

Other properties:

Commutative Property:

<em>of addition: a + b = b + a</em>

<em>of multiplication: a · b = b · a</em>

Associative Property:

<em>of addition: (a + b) + c = a + (b + c)</em>

<em>of multiplication: (a · b) · c = a · (b · c)</em>

Please help me! Write an equation in point-slope form of the line that passes through the given point and has the given slope.

Answer:

  1. y -3 = 5(x -1)
  2. y +1 = -3(x +2)
  3. y +7 = -1/4(x -4)

Step-by-step explanation:

When you are given a point and a slope, and asked for the equation in point-slope form, it is simply a matter of putting the given numbers into the appropriate places in the equation template.

  y -k = m(x -h) . . . . . . point (h, k), slope m

__

1. y -3 = 5(x -1) . . . . . . point (1, 3), slope 5

2. y +1 = -3(x +2) . . . . point (-2, -1), slope -3

  note that for k=-1, -k = -(-1) = +1; similarly the value of -h becomes +2

3. y +7 = -1/4(x -4) . . . point (4, -7), slope -1/4

What is the remainder when x^3 – 1 is divided by (x + 2)?
arlik [135]

We can just use the remainder theorem here.

Plug the value of -2 into each x variable.

(-2)^3 - 1

-9

<h3>The remainder is -9.</h3>
