Answer: D

Step-by-step explanation:

Identify the roots of gx= x2+3x-4 x^2-4x+29

### Answers

**Answer:**

x1=1

x2= -4

x3= (2 + 5i)

x4= (2 - 5i)

**Step-by-step explanation:**

STEP 1-

Find the roots of the first term.

(x^2 + 3x -4)=0

Then group the terms that contain the same variable, and move the constant to the opposite side of the equation.

(x^2 + 3x)=4

Complete the square. Remember to balance the equation by adding the same constants to each side.

(x^2 + 3x + 1.5^2)=4 + 1.5^2

(x^2 + 3x + 1.5^2)=6.25

Rewrite as perfect squares

(x + 1.5)^2=6.25

Square root both sides.

(x + 1.5) = (+/-)2.5

x= -1.5(+/-)2.5

x= -1.5 + 2.5 = 1

x= -1.5 + 2.5= -4

so the factored form of the first term.

(x^2 + 3x + 4) = (x - 1) (x + 4)

STEP 2-

Find the roots of the second term

(x^2 - 4x + 29)= 0

Group terms that contain the same variable, and move the constant to the opposite side of the equation

(x^2 - 4x)= -29

Complete the square. Remember to balance the equation by adding the same constants to each side

(x^2 - 4x + 4) = - 29 + 4

(x^2 -4x + 4) = -25

Rewrite as perfect squares

(x - 2)^2 = -25

Remember that

i = square root of -1

Square root both sides

(x - 2) = (+/-)5i

x= 2 (+/-)5i

x= 2 + 5i

x= 2 - 5i

so the factored form of the second term is

(x^2 - 4x + 29) = (x - (2 + 5i))(x - (2 - 5i))

STEP 3-

Substitute the factored form of the first and second term in g(x)

g(x) = (x-1)(x + 4)(x- (2+ 5i))(x- ( 2-5i)

Evaluate. Write your answer as a fraction in simplest form. 1/3 - 3/4 + 3/8 I need heeeelp

### Answers

**Answer:**

**Step-by-step explanation:**

8/24 - 18/24 + 9/24

-10/24 + 9/24 = -1/24

The **Simplest form **of 1/3 - 3/4 + 3/8 is -1/24.

What is Fraction?

The fractional bar is a horizontal bar that divides the numerator and denominator of every fraction into these two halves.

The **number **of **parts **into which the **whole **has been **divided **is shown by the **denominator**. It is positioned in the fraction's lower portion, below the fractional bar.How many **sections** of the **fraction** are **displayed** or **chosen **is shown in the **numerator**. It is positioned above the fractional bar in the upper portion of the fraction.

Given:

1/3 - 3/4 + 3/8

Taking **LCM **of 3, 4 and 8 we get 24.

So, 1/3 x 8/8 - 3/4 x 6/6 + 3/8 x 3/3

= 8/24 - 18/24 + 9/24

= -1/24

Hence, the **simplified** **fraction **is -1/24.

Find the value of -8 + 9.2 +-3.

### Answers

**Answer:**

-1.8

**Step-by-step explanation:**

move the numbers around a bit because there is no multiplication so 9.2-8+-3

then take out the plus so it doesn't confuse anyone 9.2-8-3

then add 8+3 which is 11 but remember to put the negative back

9.2 - 11

which gives you -1.8

**Answer:**

-1.8

**Step-by-step explanation:**

Because,

-8 + 9.2 +-3

=> 9.2 - 8 - 3 (Commutative property)

=> 9.2 - 11 (Because subtraction is done first, and a negative + a negative = a negative)

=> -1.8 will be the final answer

**Answer: D) does not exist.**

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

Explanation:

One matrix rule is that

The order is important because matrix multiplication is not commutative.

However, we're told that A and B are singular matrices. By definition, a singular matrix is one that doesn't have an inverse. This means [tex]A^{-1}[/tex] and [tex]B^{-1}[/tex] do not exist. Overall, the product of those two items is also nonexistent.

The **inverse **function of f (x) = 1/3x - 2 is f⁻¹(x) = 3(x + 2), the **value **of a is 3, and the value of x-**intercept **is x = -2.

What is a function?

Each **element **of X receives exactly one element of Y when a **function **from one **set** to the other is used. The sets X and Y are collectively referred to as the function's **domain **and **co-domain**, respectively.

**Given**:

f (x) = 1/3x - 2

Find its inverse as shown below,

Add 2 to x and then divide by 1/3 as shown below,

f⁻¹(x) = (x + 2) / 1/3

f⁻¹(x) = 3(x + 2)

compare with f⁻¹(x) = a (x + 2)

a = 3

Calculate the x-intercept by putting f(x) = 0

0 = x + 2
