Terms/Coefficients

Step-by-step explanation:

Step 1: Define

13 - 3i = -8

Step 2: Solve for i

[Subtraction Property of Equality] Subtract 13 on both sides: -3i = -21
[Division Property of Equality] Divide -3 on both sides: i = 7

Step 3: Check

Plug in i into the original equation to verify it's a solution.

Substitute in i: 13 - 3(7) = -8
Multiply: 13 - 21 = -8
Subtract: -8 = -8

Here we see that -8 does indeed equal -8.

∴ i = 7 is the solution to the equation.

What are the excluded values of x for <img src="https://tex.z-dn.net/?f=%20%5Cfrac%7Bx%2B1%7D%7Bx%5E2-1%7D%20" id="TexFormula1"

NISA [10]

Denominator:

$x^2-1=(x+1)(x-1)=\big(x-(-1)\big)(x-1)$

so excluded values are x = -1 and x = 1.

Natalia solved the problem 74.4/12=6.2. complete the model with partial products check Natalia's work using multiplication

tia_tia [17]

Answer:

Natalia's work is wrong.

Step-by-step explanation:

Natalia divided a decimal number by an entire number. Since division is a operation derived from multiplication, the best approach to check if work was good is multiplying the given result by denomination, that is:

1) $x = 6.2\times 12$ Given.

2) $x = \left(6+0.2\right)\times 12$ Definition of addition.

3) $x = 6\times 12 + 0.2\times 12$ Distributive property.

4) $x = 72 + \frac{2}{10}\times 12$ Definitions of multiplication and decimal number.

5) $x = 72 +[2\cdot (10)^{-1}]\cdot 12$ Definition of division/Associative property.

6) $x = 72 + [2\cdot 12]\cdot (10)^{-1}$ Associative property.

7) $x = 72 + 24\cdot 10^{-1}$ Definition of multiplication.

8) $x = 72 + \frac{24}{10}$ Definition of divsion.

9) $x = 72 + 2.4$ Defintion of decimal number.

10) $x = 74.4$ Definition of addition/Result

Natalia's work is wrong.
