Two solutions were found :

x =(6-√40)/2=3-√ 10 = -0.162

x =(6+√40)/2=3+√ 10 = 6.162

Step-by-step explanation:

Trying to factor by splitting the middle term

1.1     Factoring  x2-6x-1

The first term is,  x2  its coefficient is  1 .

The middle term is,  -6x  its coefficient is  -6 .

The last term, "the constant", is  -1

Step-1 : Multiply the coefficient of the first term by the constant   1 • -1 = -1

Step-2 : Find two factors of  -1  whose sum equals the coefficient of the middle term, which is   -6 .

     -1    +    1    =    0

The solutions to the equation x² + 6x + 1 = 0 are -0.177 and -5.823.

Given:

quadratic equation x² + 6x + 1 = 0

The quadratic formula states that for an equation of the form ax² + bx + c = 0, the solutions for x can be found using the following formula:

[tex]x = \dfrac{-b \pm \sqrt {(b^2 - 4ac)}}{2a}[/tex]

In our equation, a = 1, b = 6, and c = 1.

Now, let's plug these values into the quadratic formula:

[tex]x = \dfrac{-6 \pm \sqrt {(6^2 - 4(1)(1))}}{2(1)}[/tex]

x = (-6 ± √(36 - 4)) / 2

x = (-6 ± √32) / 2

Now, the two solutions for x:

1. x = (-6 + √32) / 2

      = (-6 + 5.66) / 2

      = -0.177

2. x = (-6 - √32) / 2

      = (-6 - 5.66) / 2

       -5.823

So, the solutions are -0.177 and -5.823.

Step-by-step explanation:

Answer:

Step-by-step explanation:

Discount =5% of x = 0.05x

Price after discount = x - 0.05x  = 0.95x

Tax = 5% of 0.95x = 0.05*0.95x

    =0.0475x

Price including tax = 0.95x + 0.475x = 0.9975x

Answer:

sandwich = 6.50

Step-by-step explanation:

Let s = sandwich price

d = drink price

6s + 4d = 53

4s + 6d = 47

Multiply the first equation by 3

18s + 12d = 159

Multiply the second equation by -2

-4s - 12d = -94

Add these equations together

18s + 12d = 159

-8s - 12d = -94

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

10s = 65

Divide by 10

s = 65/10

s =6.5

In conclusion,

lesser x =−1

greater =9

​

Step-by-step explanation:

The zeros of the function f(x) = (x - 4)² - 25 are -1 and 9, and the solutions from least to greatest are -1, 9.

A function has an input and an output.

A function can be one-to-one or onto one.

It simply indicated the relationships between the input and the output.

Example:

f(x) = 2x + 1

f(1) = 2 + 1 = 3

f(2) = 2 x 2 + 1 = 4 + 1 = 5

The outputs of the functions are 3 and 5

The inputs of the function are 1 and 2.

We have,

To find the function's zeros, we need to solve for f(x) = 0.

We can simplify the given function as:

f(x) = (x - 4)² - 25

= (x - 4 + 5) (x - 4 - 5)

= (x + 1)(x - 9)

Now, we can set each factor equal to zero to find the zeros of the function:

x + 1 = 0 or x - 9 = 0

Solving for x in each equation, we get:

x = -1 or x = 9

Therefore,

The zeros of the function f(x) = (x - 4)² - 25 are -1 and 9, and the solutions from least to greatest are -1, 9.

Answer:

It is nonlinear. It's a quadratic equation

Answer: Read below.

Step-by-step explanation:

[tex]3x+17<47\\-6x+9<25[/tex]

Let's take the first one.

[tex]3x+17<47[/tex]

Subtract 17

[tex]3x<47-17\\3x<30[/tex]

Divide by 3

[tex]x<\frac{30}{3}\\ x<10[/tex]

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

Now the second one.

[tex]-6x+9<25\\-6x<25-9\\-6x<16[/tex]

Here's the trick. You need to divide by -6; however, there's a rule. When you multiply or divide by negative numbers, the inequality sign flips.

[tex]x>\frac{16}{-6}[/tex]

[tex]x>-\frac{8}{3}[/tex]

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

x has to be less than 10

x has to be greater than [tex]-\frac{8}{3}[/tex] or -2.66 approximately.

in the number line, make a hollow circle on [tex]-\frac{8}{3}[/tex] and draw an arrow up to [tex]10[/tex] where, again, you have to make a hollow circle. The circles have to be hollow because neither [tex]-\frac{8}{3}[/tex] nor 10 are part of the answers.

Answer:

x=9

y=12

Step-by-step explanation:

you know what the value of x is in terms of the second equation

so put that value into the first equation

so

-5(2y-15) + 4y = 3

-10y + 75 + 4y = 3

-6y + 75 = 3

-6y = -72

y = 12 (now we have the actual value of y, just substitute this into any of the first two original functions)

x = 2(12) - 15

x = 24 - 15

x = 9

Answer:

x = 9

y = 12

Step-by-step explanation:

Answer: The slope is 4 and the y-intercept is 12.

Step-by-step explanation:

(-3,0)  and (-2,4)

find the difference in the Y values  0-4=-4

find the difference in the v- values   -3-(-2) =-1

Divide the y difference by the x difference   -4/-1 = 4 so 4 is the slope

Now to find the y intercept, use the formula y=mx + b and plot in coordinates and slope to find the y- intercept

4= 4(-2) + b

4 = -8 + b

+8    +8

b= 12  so the y intercept is 12

now the equation will be like y = 4x + 12

(-3,0)  and (-2,4)

find the difference in the Y values  0-4=-4

find the difference in the v- values   -3-(-2) =-1

Divide the y difference by the x difference   -4/-1 = 4 so 4 is the slope

Now to find the y intercept, use the formula y=mx + b and plot in coordinates and slope to find the y- intercept

4= 4(-2) + b

4 = -8 + b

+8    +8

b= 12  so the y intercept is 12

now the equation will be like y = 4x + 12

Answer:

(y²- 2y + 3) will be the answer.

Step-by-step explanation:

The given expression is (y³ - y² + y + 3) ÷ (y + 1)

By using long division method,

y + 1) y³ - y² + y + 3 (y²- 2y + 3

        y³ + y²

            - 2y² + y

            -2y² - 2y

                      3y + 3

                      3y + 3

                             0

Here the quotient is (y² - 2y + 3) and the remainder is 0.

Therefore, answer will be (y² - 2y + 3).
