The solution to the quadratic equation x² - 4x + 1 = 0 is x = ( 4 ±√12 ) / 2

A quadratic equation in its standard form is expressed as;

ax² + bx + c = 0

Where x is the unknown

To solve for x, we use the quadratic formula

x = (-b±√(b² - 4ac)) / (2a)

Given the quadratic equation in the question;

x² - 4x + 1 = 0

We substitute this values into the quadratic formula above and solve for x.

x = (-b±√(b² - 4ac)) / (2a)

x = ( -(-4) ±√( (-4)² - ( 4 × 1 × 1)) / (2 × 1)

x = ( 4 ±√( 16 - 4) ) / (2)

x = ( 4 ±√12 ) / 2

Therefore, ( 4 ±√12 ) / 2 is the solution to the equation.

Option C) ( 4 ±√12 ) / 2 is the correct answer.

Answer:

The probability is 0.08[tex]\overline 3[/tex]

Step-by-step explanation:

The choice of bread Dr Porterfield has = Pink, purple

The number of types of breads = 2

The choices of meat = Ham, turkey, beef

The number of types of meat = 3

The choice of cheese = American, Swiss, Portuguese, Japanese

The number of types of cheese = 4

The probability of selecting purple bread from pink or purple = 1/2

The probability of selecting beef or turkey from the 3 choices of meat = 2/3

The probability of selecting Japanese cheese from the fourvtypes of cheese = 1/4

Therefore, the probability he will select a sandwich on purple bread with either beef or turkey and has Japanese cheese = (1/2) × (2/3) × (1/4) = 2/24 = 1/12 = 0.08[tex]\overline 3[/tex]

Answer:

Rs. 67800

Step-by-step explanation:

Price of photograph = 60000 = 100%

Tax = x dollars = 13% of 60000

100% + 13% = 113% = 1.13

Multiply

1.13(60000) = 67800

To check, lets find 13% of 60000 and add to 60000

13% = 0.13

0.13(60000) = 7800

60000 + 7800 = 67800

Units = Rs

Rs. 67800

Answer:

x = 1

Step-by-step explanation:

x - 4 = -3

(add 4 to both sides)

x - 4 + 4 = -3 + 4

x = 1

Answer:

x = 1

Step-by-step explanation:

So you have to separate the x from the rest of the equation

so you can add 4 to both sides so x is by itself

so ur left with:

x = -3 + 4

and that is equal to x = 1

Answer:

3=0.5p

Step-by-step explanation:

The cost to get a small sundae with P toppings added represented  as 3 + 0.5p.

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.

Let's consider the toppings added to the chocolate sundae represented by p.

We will use the unitary method,

The cost of topping added to one chocolate = $0.50

The cost of topping added to p chocolate = $0.5p

So, the cost to get a small sundae with P toppings added is;

3 + 0.5p

Therefore, the cost to get a small sundae with P toppings added represented  as 3 + 0.5p
