Answers:

Additive Inverse = 1/2

Multiplicative Inverse = -2

========================================

Explanation:

The additive inverse of x is -x. The two add to 0.

So the additive inverse of -1/2 is 1/2 because -1/2+1/2 = 0.

--------------

The multiplicative inverse of x is 1/x

More thoroughly, the multiplicative inverse of a/b is b/a.

We apply the reciprocal operation here.

That means the multiplicative inverse of -1/2 is -2/1 which simplifies to -2.

We can see that (-1/2)*(-2) = 1

Any nonzero value multiplied with its multiplicative inverse will always result in 1.

Answer:

1. Additive Inverse = \frac{1}{2}

2. Multiplicative Inverse = -2

Step-by-step explanation:

An <em>"additive inverse"</em> refers to the number that is being added to another number in order to arrive at a sum of zero (0).

The additive inverse of -\frac{1}{2} is \frac{1}{2} because when you add both numbers, <u>the sum is 0.</u>

  • -\frac{1}{2} + \frac{1}{2} = 0

A <em>"multiplicative inverse"</em> refers to the number that is being multiplied to another number in order to arrive at a product of 1.

The multiplicative inverse of -\frac{1}{2} is -2 because when you multiply both, the <u>product is 1.</u>

  • -\frac{1}{2} x -2 = 1

Figure ABCD is transformed to obtain figure A′B′C′D′:
xz_007 [3.2K]

Answer:

<u>Part A</u>

  1. Reflect over the y-axis:  (x, y) → (-x, y)
    A (-4, 4) → (4, 4)
    B (-2, 2) → (2, 2)
    C (-2, -1) → (2, -1)
    D (-4, 1) → (4, 1)
  2. Shift 4 units down:  (x, y-4)
    (4, 4-4) → A' (4, 0)
    (2, 2-4) → B' (2, -2)
    (2, -1-4) → C' (2, -5)
    (4, 1-4) → D' (4, -3)

<u>Part B</u>

Two figures are <u>congruent</u> if they have the same shape and size.  (They are allowed to be rotated, reflected and translated, but not resized).

Therefore, ABCD and A'B'C'D' are congruent.  They are the same shape and size as they have only be reflected and translated.

2. Solve. x2 - 72 = 0
Effectus [21]

Answer:

x = ± 6\sqrt{2}

Step-by-step explanation:

Given

x² - 72 = 0 ( add 72 to both sides )

x² = 72 ( take the square root of both sides )

x = ± \sqrt{72} = ± \sqrt{36(2)} = ± 6\sqrt{2}

Algebra 2<br>how to simplify 2{4x-3(x+5)+10}+3(x-2)
algol13

Question: 2{4x - 3(x + 5) + 10} + 3(x - 2)

Steps

1. Expand 4x - 3(x + 5) + 10 = x - 5

= 2(x - 5) + 3(x - 2)

2. Expand 2(x - 5) = 2x - 10

=  2x - 10 + 3(x - 2)

3. Expand 3(x - 2) = 3x - 6

= 2x - 10 + 3x - 6

4. Then, simplify:

Add 2x + 3x = 5x

Add -10 - 6 = -16

5. Plug it in:

5x - 16  <-------------- Answer


Hope this helped!!!!
