Make a number line and mark the points that represent the following values of x. 5x<12

The Equation of line is y = -x + 3.

A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the

change in y coordinate with respect to the change in x coordinate as,

m = Δy/Δx where, m is the slope

Take the points (4, -1) and (0, 3).

so, the slope of line is

m = (3+ 1)/ (0-4)

m = 4/ (-4)

m = -1

So, the equation of line

y= mx+ b

y= -x + b

and, 3 = b

So, the required equation is y = -x + 3.

(2) x (14 2/3) - (10) - (8 1/3) - (12 2/3)  =   -(1 2/3) (D)

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

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

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:

  (b)  y = 3x; check using dimensions from the figure

Step-by-step explanation:

The dimensions in the larger triangle are more than the dimensions in the smaller triangle. That means the smaller dimensions need to be multiplied by a value greater than 1 to get the larger dimension. (This eliminates the 1st and 3rd choices.)

__

The figures are drawn approximately to scale, so it is easy to see that the larger triangle's dimensions are more than double (2 times) those of the smaller triangle. (This eliminates the 4th choice. 3/2 < 2)

The equation that represents the larger dimensions in terms of the smaller ones is ...

  y = 3x

__

You can check this by choosing a smaller dimension and using that in the equation:

  bottom leg = 3 in

  larger bottom leg = y = 3(3 in) = 9 in . . . . matches the diagram

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.

The correct option is;

Because the vertical line intercept the the graph more than once, the graph is of a relation but it is not a function

Step-by-step explanation:

A function is a kind of relation that maps a given set of inputs unto a set of outputs such that each of the values of the input can be linked to only one value of the output, such that the input and outputs form a set of ordered pairs

Therefore, a relation which maps a given input to more than one output is not a function, as such, given that the line intercepts the vertical line twice, then for a given value of x, which is the input, there are more than one value of y, which is the output, as such the relation is not a function.
