Answer:

x = 3

Step-by-step explanation:

Simplifying

(2x + -6) + 4(x + -3) = 0

Reorder the terms:

(-6 + 2x) + 4(x + -3) = 0

Remove parenthesis around (-6 + 2x)

-6 + 2x + 4(x + -3) = 0

Reorder the terms:

-6 + 2x + 4(-3 + x) = 0

-6 + 2x + (-3 * 4 + x * 4) = 0

-6 + 2x + (-12 + 4x) = 0

Reorder the terms:

-6 + -12 + 2x + 4x = 0

Combine like terms: -6 + -12 = -18

-18 + 2x + 4x = 0

Combine like terms: 2x + 4x = 6x

-18 + 6x = 0

Solving

-18 + 6x = 0

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '18' to each side of the equation.

-18 + 18 + 6x = 0 + 18

Combine like terms: -18 + 18 = 0

0 + 6x = 0 + 18

6x = 0 + 18

Combine like terms: 0 + 18 = 18

6x = 18

Divide each side by '6'.

x = 3

Simplifying

x = 3

Answer:

the answer is 6x-18

Answer:

Step-by-step explanation:

1). m∠AEC = m∠AEB + m∠BEC

                  = 21° + 37°

                  = 58°

2). m∠BED = m∠BEC + m∠CED

                   = 37° + 44°

                   = 81°

3). m∠IKF = m∠IKH + m∠HKG + m∠GKF

                = m∠IKH + m∠HKG + m∠IKH [Since, ∠IKH ≅ ∠GKF]

                = 2∠IKH + m∠HKG

         103° = 2∠IKH + 41°

   2(∠IKH) = 103 - 41

 m(∠IKH) = 31°

4). m∠AED = m∠AEB + m∠BEC + m∠CED

                  = 21° + 37° + 44°

                  = 102°

5). m∠JKG = 108°

    m∠JKG = m∠JKI + m∠IKH + m∠HKG

    108° = m∠JKI + 31° + 41°

    m∠JKI = 108° - 72°

    m∠JKI = 36°

6). m∠HKF = m∠GKF + m∠HKG

                  = m∠IKH + m∠HKG [Since, m∠GKF = m∠IKH]

                  = 31° + 41°

                  = 72°

7). m∠NQO = m∠MQN = 64°

8). m∠JKF = m∠JKI + m∠IKF

                 = 36° + 103°

                  = 139°

8). m∠MQO = 2(m∠NQO)

                    = 2(64)°

                    = 128°

9). m∠LQO = 156°

    m∠LQM = m∠LQO - m∠MQO

                    = 156° - 128°

                    = 28°

10. m∠NQP = m∠NQO + m∠OQP

                   = 64° + m∠LQM [Since ∠OQP ≅ ∠LQM]

                   = 64° + 28°

                   = 92°

Answer:Look at the step by step it’s correct

Step-by-step explanation:

A quadratic equation is an equation whose leading coefficient is of second degree also the equation has only one unknown while it has 3 unknown numbers. The correct option is D.

A quadratic equation is an equation whose leading coefficient is of second degree also the equation has only one unknown while it has 3 unknown numbers. It is written in the form of ax²+bx+c.

Suppose that the given quadratic equation is

 ax² + bx + c = 0

Then its roots are given as:

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

For the given equation, the value of a, b, and c is 1, -10, and 125, respectively. The roots of the given quadratic equation are,

[tex]x = \dfrac{-b \pm \sqrt{b^2 - 4ac}}{2a}\\\\x = \dfrac{-(-10) \pm \sqrt{(-10)^2 - 4(1)(125)}}{2(1)}\\\\x = \dfrac{10 \pm \sqrt{100 - 500}}{2}\\\\x = \dfrac{10 \pm 20i}{2}\\\\[/tex]

x = 5 ± 10i

Hence, the correct option is D.

Step-by-step explanation:

(a)

A least square regression line is to be formed for predicting beak heat loss, as a percent of total body heat loss, from temperature.

Use MS-Excel to form the regression line.

Go to Data → Data Analysis → Regression

A dialog box will open.

Select the X and Y variables.

Press OK.

The regression output is attached below.

The equation of the least‑squares regression line is:

[tex]\hat y=0.919+2.065x[/tex]

(b)

The coefficient of determination R² specifies the percentage of the variance in the dependent variable (Y) that is forecasted or explained by linear regression and the forecaster variable (X, also recognized as the independent variable).

Consider the regression output attached below.

The R² value is 0.8360.

That is 83.6% of the variation in beak heat loss is explained by the straight‑line relationship with temperature.

The 8-count pack of AA batteries has a lower unit prices of $0.78 per battery.

Option B is correct.

Division in mathematics is the process of breaking a number up into equal parts, and finding out how many equal parts can be made. For example, dividing 15 by 3 means splitting 15 into 3 equal groups of 5.

According to the question

Unit price of 8 AA batteries

= 6.24 ÷ 8

= 0.78

Unit price of 20 AA batteries

= 15.8 ÷ 20

= 0.79

Since, 0.78 < 0.79

Therefore, the unit price of 8 AA batteries is low.

Option B is correct.

Answer:

Step-by-step explanation:

Given:

The number of bacteria in a culture is increasing according to the law of exponential growth.

After 2 hours, there are 50 bacteria, and after 5 hours, there are 400 bacteria.

To find:

The number of bacteria after 7 hours.

Solution:

Let y be the number of bacteria after x hours.

The general exponential growth model is

[tex]y=ab^x[/tex]

where, a is initial value and b is growth factor.

After 2 hours, there are 50 bacteria. So, the point is (2,50). Put x=2 and y=50.

[tex]50=ab^2[/tex]         ...(ii)

After 5 hours, there are 400 bacteria. So, the point is (5,400). Put x=5 and y=400 in general exponential growth model.

[tex]400=ab^5[/tex]       ...(iii)

Divide equation (iii) by (ii).

[tex]\dfrac{400}{50}=\dfrac{ab^5}{ab^2}[/tex]  

[tex]8=b^3[/tex]

Taking cube root on both sides, we get

[tex]b=2[/tex]

Put b=2 in (ii).

[tex]50=a(2)^2[/tex]  

[tex]50=4a[/tex]

[tex]\dfrac{50}{4}=a[/tex]

[tex]a=12.5[/tex]

Put a=12.5 and b=2 in (i).

[tex]y=12.5(2)^x[/tex]

This is the equation which represents number of bacteria after x hours.

Put x=7 in the above equation.

[tex]y=12.5(2)^7[/tex]

[tex]y=12.5(128)[/tex]

[tex]y=1600[/tex]

Therefore, the number of bacteria after 7 hours is 1600.

Answer:

a = (D-b) / 2

Step-by-step explanation:

Goal : move "a" to the left side and everything else to the right side

D=2a+b   (swap left and right sides)

2a + b = D    (subtract b from both sides)

2a = D - b   (divide both sides by 2)

a = (D-b) / 2   (answer)

The solution of the formula expressed 'a' in terms of the variable D and b is given by a = (D - b) / 2.

To solve the formula D = 2a + b for 'a', we need to isolate 'a' on one side of the equation.

Subtract 'b' from both sides of the equation to move it to the right-hand side.

D - b = 2a

To solve for 'a', we need to get rid of the coefficient of 'a', which is 2. Divide both sides of the equation by 2.

(D - b) / 2 = a

The equation (D - b) / 2 = a is the solution for 'a' in general.

formula D = 2a + b, 'D' is expressed in terms of 'a' and 'b'.

To solve for 'a', we want to find an expression that represents 'a' on its own without any other variables on the right-hand side of the equation.

Perform inverse operations to isolate 'a'.

first, move the 'b' term to the right side by subtracting 'b' from both sides. This step ensures that all the terms involving 'a' are on one side of the equation.

Next, divide both sides by the coefficient of 'a', which is 2, to cancel out the multiplication of 'a'.

This step leaves 'a' alone on the left side, thus giving us the solution for 'a'.

Therefore, the required formula is (D - b) / 2 = a, expresses 'a' in terms of 'D' and 'b'.
