Answer:

x=-5

Step-by-step explanation:

-12x-7=53

     +7=+7

-12x=60

divide both sides by negative 12

60/-12= -5

so x =-5

The solution of the linear equation with a single variable - 12x - 7 = 53 will be -5.

The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.

A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.

The equation with a single variable 'x' is given below.

- 12x - 7 = 53

Simplify the equation, then we have

- 12x - 7 = 53

- 12x = 60

x = 60 / (-12)

x = - 5

The solution of the linear equation with a single variable - 12x - 7 = 53 will be -5.

to get the slope of any straight line, we simply need two points off of it, hmm from the table let's use hmmm (2 , 0) and (4 , -2)

[tex](\stackrel{x_1}{2}~,~\stackrel{y_1}{0})\qquad (\stackrel{x_2}{4}~,~\stackrel{y_2}{-2}) ~\hfill \stackrel{slope}{m}\implies \cfrac{\stackrel{rise} {\stackrel{y_2}{-2}-\stackrel{y1}{0}}}{\underset{run} {\underset{x_2}{4}-\underset{x_1}{2}}}\implies \cfrac{-2}{2}\implies -1[/tex]

Step-by-step explanation:

To find the slope, take 2 points from the graph. I'm going to pick (0,2) and (1,1). Whenever we find the slope this way, we need to keep this formula in mind:

[tex] \frac{y2 - y1}{x2 - x1} = slope[/tex]

So, in this case, we need to do this:

[tex] \frac{1 - 2}{1 - 0} = \frac{ - 1}{1} [/tex]

So the answer is -1.

The total perimeter here is P =21x + 7

Step-by-step explanation:

Let W and L represent the width and length of the rectangle.  Then the perimeter is P = 2W + 2L.  Substituting 3x + 1 for W and 3(3x + 1) for L, we get

P = 2(3x + 1) + 2*3*(3x + 1), or P = 7(3x + 1) = P =21x + 7

The measure of center that would best describe a typical value of the data set is a mean since the values are close.

It should be noted that the measure of center include the mean, median, mode, and the mid-range.

In this case, when there is a close distribution of different numbers, he beta measurement will be the mean.

Therefore, the mean of the numbers will be:

= (20 + 21 + 21 + 25 + 20 + 23 + 27 + 23 + 24 + 25 + 26 + 24 + 23 + 22 + 24)/15
