Identify the error and fix the mistake

**Answer:**

x = (9 ±√201**)** ÷ 12

**Step-by-step explanation:**

6x² -5x -9 = 0 ( rearranged)

a = 6 b = -5 c = -9

- - 9 = 9

-9² = **81** (the 81 must be positive, this is one error)

-4 x 6 x **-5 = **120 ( the 5 must be a minus number, this is one error)

120 + 81 = **201**

Wilson Green sells home security systems. He earns an 13% commission on every system he sells. Wilson's sales for this month totaled $6425. What is Wilson's commission? *

**Answer**

$835,25

**Explanation**

Total sales = $6425

Commission = 13%

Castel and Kali are selling wrapping paper for a school fundraiser. Customers can buy rolls of plain wrapping paper and rolls of holiday wrapping paper. Castel sold 2 rolls of plain wrapping paper and 5 rolls of holiday wrapping paper for a total of $89. Kali sold 9 rolls of plain wrapping paper and 10 rolls of holiday wrapping paper for a total of $213. What is the cost each of one roll of plain wrapping paper and one roll of holiday wrapping paper?

please help, am not good at word problems. I will also give the brainliest answer.

**Answer:**

Plain is $7 and Holiday is $15

**Step-by-step explanation:**

Castel: 2p + 5h = 89

Kali: 9p + 10h = 213

Double Castel's: 4p + 10h = 178

Subtract fro Kali's 9p + 10h = 213

- 4p + 10h = 178

5p = 35

p = 7 Plain is $7

Substitute 7 into one of the equations and solve for h:

2(7) + 5h = 89

14 + 5h = 89

5h = 75

h = 15 Holiday is $15

RS is the perpendicular bisector of TU. Find x and y

**Answer:**

x = 1

y = 30°

**Step-by-step explanation:**

is RS is ⊥ to TU then TS = US so we can use this equation to find 'x':

20x-3 = 5x+12

15x = 15

x = 1

we also know that RS intersecting with TU creates a 90° angle

if 3y = 90 then y = 30

What is the remainder when (x3 1) is divided by (x2 â€"" x 1)?.

The **remainder **of the **equation **is [tex]\rm x+1[/tex].

Given that,

When the **equation** is [tex]x^3+1[/tex] **divided **by [tex]x^2-x+1[/tex].

We have to **determine**,

The **remainder** for the **equation**?

**According **to the **question**,

The **equation **[tex]x^3+1[/tex] is **divided **by [tex]x^2-x+1[/tex].

On the **division **of the **polynomial**, the **remainder **is,

[tex]\dfrac{\rm x^3+1}{x^2-x+1}[/tex]

**Factorize **the **equation **to **convert **this into the **simplest form**,

[tex]\rm = x^3+1\\\\=x^3-x^2+x + x^2-x+1\\\\= x ( x^2-x+1) + 1(x^2-x+1)\\\\= (x+1) (x^2-x+1)[/tex]

Now, the **equation **can be **written **as,

[tex]\rm = \dfrac{(x+1) (x^2-x+1) }{ x^2-x+1}\\\\= x+1[/tex]

Hence, The required **remainder **of the **equation **is [tex]\rm x+1[/tex].

Do the ratios 18 7 and 2 1 form a proportion?

Hi!

There are a few ways we can do this. The first one is this:

**The ratios 18:7 and 2:1 can be represented as fractions: **[tex]\frac{18}{7}[/tex]** and **[tex]\frac{2}{1}[/tex]

*To see if they are proportions, we can put the fractions in their simplest form and see if they are equal. However, they are already simplified, and we can see that they are **not equal*.

**Therefore they are not proportions.**

The second way we can see is to use cross products. Once again we'll put them as fractions, except we'll set them side by side, like so:

[tex]\frac{18}{7}[/tex] [tex]\frac{2}{1}[/tex]

*To see if they are proportions, we simply multiply the diagonals. These would be 18 x 1 and 7 x 2 which equals 18 and 14. These are not equal.*

*Therefore they are not proportions.*

A 50

E 200

B 110

**Step-by-step explanation:**

The probability of getting heads or tails is 50%.

300*50% = 150

**Answer:**

C. 150 times

If f(x) = x2 - 1 and g(x) = 2x - 3, what is the domain of (fog)(x)?

**Answer:**

domain will be ( -∞, ∞)

**Step-by-step explanation:**

The given functions are f(x) = x² - 1 and g(x) = 2x - 3

We have to find domain of (fog)(x)

We will find the function (fg)(x) first.

(fog)(x) = f[g(x)]

= (2x - 3)²

= 4x² + 9 - 12x - 1

= 4x² - 12x + 8

= 4 (x² - 3x + 2)

The given function is defined for all values of x.

Therefore, domain will be ( -∞, ∞)

43. Write a system of equations that is equivalent to each of the systems of equations below

2x + 3y = 4

12x+3y=1

X-7y=8

5x+4y=20

1.

The** **new system of **equivalent equations** are **4x + 6y = 8 and 12x + 3y = 1**

To get an **equivalent equation**, we multiply the original equation by a constant and replace it with the new equation.

So, 2x + 3y = 4 (1)

12x + 3y = 1 (2)

We multiply equation (1) by 2

So, 2x + 3y = 4 (1) × 2

⇒4x + 6y = 8 (3)

Replacing (1) by (3), we have

**4x + 6y = 8 (3) **

**12x + 3y = 1 (2) **

So, the** **new system of **equivalent equations** are **4x + 6y = 8 and 12x + 3y = 1.**

2.

The** **new system of **equivalent equations** are **3x - 21y = 24 and 5x + 4y = 20**

To get an **equivalent equation**, we multiply the original equation by a constant and replace it with the new equation.

So,

x - 7y = 8 (1)

5x + 4y = 20 (2)

We multiply equation (1) by 3, we have

So, x - 7y = 8 (1) × 3

⇒3x - 21y = 24 (3)

Replacing (1) by (3), we have

**3x - 21y = 24 (3)**

**5x + 4y = 20 (2)**

So, the** **new system of **equivalent equations** are **3x - 21y = 24 and 5x + 4y = 20.**
