Answer:

x = -30

Step-by-step explanation:

Let x be the number.

2(x + 9) = x - 12

Use distributive property of multiplication

2x + 18 = x - 12

Simplify by combining like terms

2x - x = -12 - 18

x = -30

The slope of this line is 2

Step-by-step explanation:

If a = 4 and m = –3, evaluate a – 3m.

= Solution,

= a - 3m

= 4 - 3 ( - 3 )

= 4 + 9

= 13

Answer:

13 is the answer :)

Step-by-step explanation:

If,

a = 4 and m = -3

Then a - 3m ,

4 - 3(-3)

4+9

= 13

Answer:

7238.23

Step-by-step explanation:

The mean absolute deviation for the number of hours students practiced the violin is 6.4.

The average absolute deviation of the collected data set is the average of absolute deviations from a center point of the data set.

Given

Students reported practicing violin during the last semester for 45, 38, 52, 58, and 42 hours.

The given data set is;

45, 38, 52, 58, 42

Mean Deviation = Σ|x − μ|/N.

μ = mean, and N = total number of values

|x − μ| = |45 − 47| = 2

|38− 47| = 9

|52− 47| = 5

|58− 47| = 11

|42− 47| = 5

The mean absolute deviation for the number of hours students practiced the violin is;

[tex]\rm Mean =\dfrac{2+9+5+11+5}{5}\\\\Mean=\dfrac{32}{5}\\\\Mean = 6.4[/tex]

Hence, the mean absolute deviation for the number of hours students practiced the violin is 6.4.

Answer:

c) [tex]a_{n}[/tex] = 3.5n + 7.5

Step-by-step explanation: =>

Given :-

a = 11

d = 3.5

To Find :

[tex]a_{n}[/tex]

Solving :-

= a + (n - 1)d

= 11 + 3.5n - 3.5

Water cycle involves all processes in which water circulates

The water cycle labeled C is precipitation

From the figure, we can see that the step C represents water falling down from the sky to the earth surface.

This can represent rain, sleet, or snow.

Any of the above forms represent precipitation

Hence, the water cycle labeled C is precipitation

The value of the stock change that week is -1 2/3.

The fractional bar is a horizontal bar that divides the numerator and denominator of every fraction into these two halves.

Given:

The value of a stock increases 14 2/3 points twice in one week.

and, The other three days the value decreases by 10 points, 8 1/3 points, and 12 2/3 points.

So, the point in that week

= 2 x 14 2/3 - 10 - 8 1/3 - 12 2/3

= 2 x 44/3 - 10 - 25/3 - 38/3

= 88/3 - 10 - 63/3

= 88/3 - 10 - 21

= 88/3 - 31

= 88- 93/ 3

= - 5/3

= - 1 2/3

The inequality equation is 3L ≤ 27 or L ≤ 9 feet , where L is the length

Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.

In an inequality, the two expressions are not necessarily equal which is indicated by the symbols: >, <, ≤ or ≥.

Given data ,

Let the inequality equation be represented as A

Now , the value of A is

Let the length of the equilateral triangle be L

And , each of the lengths of the triangle is at most 9 feet long means that each of the lengths is less than or equal to 9 feet

So , L ≤ 9 feet

And , the perimeter of an equilateral triangle is the addition of the three equal lengths

So , 3L ≤ 27 feet

Therefore , the value of A is 3L ≤ 27 feet

Hence , the inequality equation is 3L ≤ 27 feet

Answer:

The answer is

[tex] \huge y = - \frac{5}{4} x - 3[/tex]

Step-by-step explanation:

To find an equation of a line given the slope and a point we use the formula

[tex]y - y_1 = m(x - x_1)[/tex]

where

m is the slope

( x1 , y1) is the point

From the question the point is (-4,2) and slope of -5/4

We have

[tex]y - 2 = - \frac{5}{4} (x + 4) \\ y - 2 = - \frac{5}{4} x - 5 \\ y = - \frac{5}{4} x - 5 + 2[/tex]

We have the final answer as

[tex]y = - \frac{5}{4} x - 3 \\ [/tex]
