\huge\boxed{x=-6}

Hey there! Our goal here is to isolate the variable on one side of the equation.

\begin{aligned}-7(x+6)&=4(x+6)&&\smash{\Big|}&&\textsf{Start with the original equation.}\\-7x+(-7)(6)&=4x+4(6)&&\smash{\Big|}&&\textsf{Distribute.}\\-7x-42&=4x+24&&\smash{\Big|}&&\textsf{Multiply.}\\-7x-4x&=24+42&&\smash{\Big|}&&\textsf{Move the terms.}\\-11x&=66&&\smash{\Big|}&&\textsf{Combine like terms.}\\x&=\boxed{-6}&&\smash{\Big|}&&\textsf{Divide both sides by $-11$.}\end{aligned}

Answer: The answer is x=–6.

Step-by-step explanation: Step 1: Simplify both sides of the equation:

(-7)(x)+(-7)(6)=(4)(x)+(4 )(6) (Distributive Property)

-7x+-42=4x+24

-7x-42=4x+24

Step 2: Subtract 4x by the both sides: -7x-42-4x=4x+24-4x

-11x-42=24

Step 3: Add 42 to the both sides: -11x-42+42=24+42

-11x=66

And step 4: Divide both sides by -11: \frac{-11x}{-11}=\frac{66}{-11}, x=-6.

I hoped this formula step-by-step is very helpful, please mark me as brainliest, and have a happy holidays! :D

Using a proportion, what can you infer about the number of households in her town that have more than three children?
eduard

Answer:

About 296 households have more than three children.

Step-by-step explanation:

The complete question is:

Carmen used a random number generator to simulate a survey of how many children live in the households in her town. There are 1,346 unique addresses in her town with numbers ranging from zero to five children. The results of 50 randomly generated households are shown below. Children in 50 Households Number of Children Number of Households 0 5 1 11 2 13 3 10 4 9 5 2 Using a proportion, what can you infer about the number of households in her town that have more than three children? About 242 households have more than three children. About 269 households have more than three children. About 296 households have more than three children. About 565 households have more than three children.

Solution:

The data provided for the number of children and number of households is:

Number of Children (<em>X</em>)          Number of Households (<em>f</em> (X))

               0                                                   5

               1                                                    11

               2                                                   13

               3                                                   10

               4                                                    9

               5                                                    2

           TOTAL                                             50

Compute the probability of households having more than three children as follows:

P (More than 3 children) = P (4 children) + P (5 children)

                                        =\frac{9}{50}+\frac{2}{50}

                                        =\frac{11}{50}

                                        =0.22

Let the random variable <em>Y</em> be defined as the number of households having more than three children.

The probability of the random variable <em>Y </em>is, <em>p</em> = 0.22.

The entire population, i.e. total number of addresses in Carmen's town with numbers ranging from zero to five children, consists of <em>N</em> = 1,346 households.

Compute the expected number of households having more than three children as follows:

E(Y) =N\times p

         =1346\times 0.22\\=296.12\\\approx 296

Thus, about 296 households have more than three children.

Given that tan(x)= -4/7, and 270 degrees&lt; x&lt; 360 degrees, what is the exact value of sec(x)
Maurinko [17]

Answer:

sec(x) = 1.15

Step-by-step explanation:

We can figure out what x is by using the arctan(x) function:

x = arctan(-\frac{4}{7}) = -29.74

So, now let's figure out the cos(x) as sec(x) is equal to the reciprocal of cos(x):

cos(-29.74) = 0.87

Let's take the reciprocal:

sec(x) = \frac{1}{cos(-29.74)} = 1.15

And that's your answer.
