Answer:

[tex]x=3[/tex]

Step-by-step explanation:

The first step is to isolate the variable on one side. In this case, let's try to bring x to the right. We do this by adding 3x to both sides, which gives us:

[tex]7 = 2x + 1[/tex]

Now, to have just the x term on the right, we subtract one from both sides of the equation, giving:

[tex]6 = 2x[/tex]

The last step is to divide both sides by two to leave x by itself. Thus, after dividing, we get:

[tex]3 = x[/tex]

Hope this helps!

Answer:

QS = 38

Step-by-step explanation:

First, we need to find the value of x.

Given that R is the midpoint of Q and S, that means QR = RS.

6x-11 = 2x+9

Solve.

x = 5.

To find QS, we need to solve the following equation:

6x-11 + 2x+9

Substitute 5 for x.

6(5)-11+2(5)+9

30-11+10+9

1. [tex]f(x) = 6x + 14[/tex]

2. $14 flat fee

Step-by-step explanation:

In this case, [tex]f(x)[/tex] where [tex]x[/tex] is time (hour). $14 dollar stays constant when [tex]x = 0[/tex]. This is the flat rate fee.

Let's do a sanity check:

[tex]f(1) = 6(1) + 14 = 20[/tex]

[tex]f(1.5) = 3(1.5) + 14 = 23[/tex]

[tex]f(2) = 6(2) + 14 = 26[/tex]

Answer:

2000 eels

Step-by-step explanation:

Let us represent the total estimate of the eels = x

She returns the 50 eels to the lake.

The next day Hannah catches 400 eels, of these 400 eels, 10 are ringed.

To solve the above question, we have the following:

50/x = 10/400

Cross Multiply

10x = 50 × 400

x = 50 × 400/10

x = 2000 eels

Therefore, the total estimate of the eels in the lake = 2000 eels

Answer:

NO

Step-by-step explanation:

Thats an absolute value function, an absolute value function can not be negative

Answer:

Not a function.

Step-by-step explanation:

Do the vertical line test. If a line can go from top to bottom and touch the line twice, then it is not a function. A line like this would touch twice on this graph, so it is not a function.

Step-by-step explanation:

Simplifying

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

Reorder the terms:

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

Reorder the terms:

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

Remove parenthesis around (-2 + 3x)

-3 + 6x = -2 + 3x

Solving

-3 + 6x = -2 + 3x

Solving for variable 'x'.

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

Add '-3x' to each side of the equation.

-3 + 6x + -3x = -2 + 3x + -3x

Combine like terms: 6x + -3x = 3x

-3 + 3x = -2 + 3x + -3x

Combine like terms: 3x + -3x = 0

-3 + 3x = -2 + 0

-3 + 3x = -2

Add '3' to each side of the equation.

-3 + 3 + 3x = -2 + 3

Combine like terms: -3 + 3 = 0

0 + 3x = -2 + 3

3x = -2 + 3

Combine like terms: -2 + 3 = 1

3x = 1

Divide each side by '3'.

x = 0.3333333333

Simplifying

x = 0.3333333333

Answer:

C. r = 3 - cos theta

Step-by-step explanation:

The other user who answered was correct.

The equation is belongs to the graph of the limacon curve is r = 3 - cos [tex]\theta[/tex]

The correct option is C.

At θ = 180°, the value of r is positive, but just a fraction of the value at

θ = 0°. This eliminates choices 'b' and 'd'.

As,  the equation of a horizontal cardiod is r= a ± a cos θ.

Here, from the figure we have horizontal cardiod.

Then, the equation is belongs to limacon curve is r = 3 - cos [tex]\theta[/tex].

Answer:

Means

sample 1: 3.6

sample 2: 3.3

sample 3: 3.8

Step-by-step explanation:

Three or four times. All of these means are no less than three but no more than four this means that the average number of times is between three or four

a) The mean of the sample 1 = 3.6

b) The mean of the sample 2 = 3.3

c) The mean of the sample 3 = 3.8

d) In one month, the average diner would visit the restaurant 3 or 4 times

The mean value in a set of numbers is the middle value, calculated by dividing the total of all the values by the number of values.

Mean = Sum of Values / Number of Values

Given data ,

Let the mean of the sample 1 be represented as M₁

Let the mean of the sample 2 be represented as M₂

Let the mean of the sample 3 be represented as M₃

where the number of visits to restaurant in one month is given by

Sample 1 = { 5 , 2 , 6 , 4 , 4 , 7 , 2 , 1 , 2 , 3 }

The number of visits = 10 visits

The total sum of sample 1 = 36

So , mean M₁ = 36/10 = 3.6

And , Sample 2 = { 2 , 6 , 1 , 3 , 4 , 5 , 2 , 1 , 5 , 4 }

The number of visits = 10 visits

The total sum of sample 1 = 33

So , mean M₂ = 33/10 = 3.3

And , Sample 3 = { 3 , 3 , 6 , 4 , 1 , 5 , 3 , 4 , 4 , 5 }

The number of visits = 10 visits

The total sum of sample 1 = 38

So , mean M₃ = 38/10 = 3.8

And , the average diner would visit the restaurant 3 or 4 times because the mean value of the three samples lies between 3 and 4

Hence , the mean of the sample is solved
