To find the mean of a dot plot, add up all of the data and divide by how many numbers there are.

In this case, the data added up is 4 + (5 x 4) + (6 x 3) + (7 x 2) + 10

4 + (5 x 4) + (6 x 3) + (7 x 2) + 10 = 66

With this information, we can now find the mean.
66/11=6

Therefore, the mean is 6. Hope this helps! Feel free to ask any questions.

What is the equation of the line that is parallel to the line y = - 1/3x + 4 and passes through the point (6, 5)?

Lostsunrise [7]

Answer:

$y=-\frac{1}{3}x+7$

Step-by-step explanation:

we know that

If two lines are parallel then their slopes are equal

The equation of the given line is

$y=-\frac{1}{3}x+4$

the slope is $m=-\frac{1}{3}$

the slope of the parallel line to the given line is also $m=-\frac{1}{3}$

Find the equation of the line that is parallel to the given line and passes through the point (6, 5)

we have

$m=-\frac{1}{3}$

$point\ (6,5)$

The equation of the line in point slope form is

$y-y1=m(x-x1)$

substitute

$y-5=-\frac{1}{3}(x-6)$

Convert to slope intercept form

$y=mx+b$

isolate the variable y

$y-5=-\frac{1}{3}x+2$

$y=-\frac{1}{3}x+2+5$

$y=-\frac{1}{3}x+7$

What is the true solution to the equation below 2 log3(6x)-log3(4x)=2 log 3(x+2)

Tanya [424]

Answer: The answer is (C) C. x=1 and x=4.

Step-by-step explanation: We are given to find the true solution of the following equation involving logarithms:

$2\log_36x-\log_34x=2\log_3(x+2).$

We will be using the following properties of logarithms in the solution.

$(i)~a\log b=\log a^b,\\\\(ii)~\log a-\log b=\log\dfrac{a}{b}.$

The solution is as follows:

$2\log_36x-\log_34x=2\log_3(x+2)\\\\\Rightarrow \log_3(6x)^2-\log_34x=\log_3(x+2)^2\\\\\\\Rightarrow \log_3\dfrac{36x^2}{4x}=\log_3(x^2+4x+4)\\\\\\\Rightarrow 9x=x^2+4x+4\\\\\Rightarrow x^2-5x+4=0\\\\\Rightarrow (x-4)(x-1)=0\\\\\Rightarrow x-4=0,~~~x-1=0\\\\\Rightarrow x=4,~~~x=1.$

Since we can find the logarithm of a positive integer only, and both the solutions x = 1 and 4 satisfy this condition after substituting in the given equation, so both the solutions are TRUE.

Thus, the correct option is (C).

Solve the equation:12(5−m)=7−(1+3m) Question 2 options: -27 -6 6 6.625

kramer

12(5-m) = 7 -(1+3m) distribute

60-12m = 7 -1-3m combine like terms

60 - 12m = 6 -3m add 12m to both sides

60 = 6 + 9m subtract 6 from both side

54 = 9m divide by 9

6 = m
