Answer: f(x)= 2x-3

Step-by-step explanation: The formula for slope is y=mx+b, where m is equal to the slope of the line and b is equal to the y-intercept. We can find the slope by looking at the line OR solving algebraically using the following calculations:

(y2-y1)/(x2-x1)

Pick 2 points on the line and plug in.

(x1,y1)-->(2,1) and (x2,y2)-->(3,3)

(3-1)/(3-2)=2/1=2

So, the slope of the line is 2. m=2.

To find the y-intercept, we can solve algebraically or look at the graph.

y=2x+b

Plug in a point from the graph to find b, the y-intercept.

3=2(3)+b

3=6+b

-3=b

So, the y-intercept is b.

Now, we plug our values into the slope intercept equation, y=mx+b

y=2x-3

Again, you look look at the graph and see where x=0 is to find the y intercept. To find the slope you can use rise/run and count to see that to get from one point on the graph to the next, you count up 2 (rise 2) and to the right 1 (run 1) which gives you 2/1. 2/1 is equal to 2, giving you the slope of 2.

The median will be used as the measure of central tendency in this case, it is wise to use the inter-quarterly range as the measure of spread.

A histogram for symmetrical data will give a symmetrical shape, and the mean, median and mode will all be the same value. Therefore, the best measure of the central tendency to use is the mean.

The standard deviation indicates; how far away the values in a given data set are from the mean, and since the mean is used as the measure of central tendency, then the standard deviation should be used as the spread.

If the data is symmetrical, then the mean is the measure of central tendency; and the standard deviation is the best spread to use.

If the data is asymmetrical, the median is the best measure of central tendency; and the inter-quarterly range is the best spread to use.

The median will be used as the measure of central tendency in this case, it is wise to use the inter-quarterly range as the measure of spread.

Answer:

y = -35x -3

Step-by-step explanation:

We can use the formula y = mx + c to find the equation of the line.

Here,

m ⇒ slope

c ⇒ y-intercept

From these, they have already given the slope of the line.

m ⇒ -35

And now we have to find the c ( y-intercept ) of the line using the given coordinate,

( 0 , -3 ) ⇒ ( x , y )

So, to find the y-intercept you have to replace x, y & m with 0, -3 & -35 respectively, and solve for c.

Let us solve it now.

y = m x + c

-3 = -35 × 0 + c

-3 = 0 + c

-3 = c

And now we can write the equation of the line like this.

y = m x + c

y = -35x -3

Answer:

Equation of line is given as y =mx + c, where m is the slope and c is the y-intercept.

Since slope is -35, equation of line is y = -35x + c.

Substitute (0,-3) into equation to find c.

-3 = -35(0) + c

c = -3

Hence, equation is y = -35x - 3.

Answer:

  20 m

Step-by-step explanation:

You want to know the uniform width of a lawn around a 120 m by 80 m building such that the area of the lawn is equal to the area of the building.

Let x represent the width of the lawn. Then the dimensions of the area that includes the lawn and building will be (120 +2x) meters by (80 +2x) meters. We want that area to be equal to twice the area of the building:

  (120 +2x)(80 +2x) = 2(120·80)

Dividing by 4 gives a slightly simpler equation.

  (60 +x)(40 +x) = 60(80)

  2400 +100x +x^2 = 4800 . . . . eliminate parentheses

  x^2 +100x -2400 = 0 . . . . . . subtract 4800 and put in standard form

  (x +120)(x -20) = 0 . . . . . . . factor

Values of x that make the factors zero are ...

  x = -120, x = 20

Only the positive solution makes any sense in this context.

The width of the lawn must be 20 m.

__

Additional comment

The total area of the plot is ...

  total area = (building area) + (lawn area)

When the lawn area is equal to the building area, then we have ...

  total area = (building area) + (building area)

  total area = 2·(building area)

This is the relation we used in the solution above.

The angles of triangle LMN in order from least measure to the greatest measure as angle ∠ N < angle ∠ M < angle ∠ L which is determined by the triangle inequality theorem.

When two lines intersect at a location, vertical angles are generated. They are always equal to each other.

The length of each side of the given triangle LMN is shown below.

LM = 18 cm

MN = 29 cm

LN = 20 cm

According to the triangle inequality theorem, in a triangle, the largest angle is the one opposite to the longest side of the triangle.

Therefore, in triangle LMN, we have the greatest angle as angle ∠ L

And the smallest angle is ∠ N

Arrange the angles in ascending order,

angle ∠ N < angle ∠ M < angle ∠ L

Thus, the angles of triangle LMN in order from least measure to the greatest measure as angle ∠ N < angle ∠ M < angle ∠ L.

Arithmetic, Common Difference = -9

The Correct option is (b).

What is Common Difference?

The common difference of an arithmetic sequence is the difference between any of its terms and its previous term. An arithmetic sequence goes from one term to the next by always adding (or subtracting) the same amount. The number added (or subtracted) at each stage of an arithmetic sequence is called the "common difference", because if we subtract (that is if you find the difference of) successive terms, you'll always get this common value. Most often, "d" is used to denote the common difference.

Given,

x =    1     2      3      4

f(x)=  81   72   63    54

Now, According to the question:
2nd term - 1st term = 72 - 81 = -9

3rd term - 2nd term = 63 - 72 = -9

4th term - 3rd term  = 54 - 63 = -9

Hence, Arithmetic, Common Difference = -9

Answer:

<XMN = 122°

Step-by-step explanation:

An angle around a point is 360°

If LMN = 145° then the rest would be 360 - 145

360 - 145 = 215

4x + 5 + 6x - 10 = 215

Simplify = 10x - 5 = 215

work out = 215 + 5 = 220 ÷ 10 = 22

x = 22

XMN = 6x - 10

6 × 22 = 132

132 - 10 = 122

Answer:

[tex]y=\frac{3}{2}x+7[/tex]

Step-by-step explanation:

To write the equation of a line, two information are needed.

The slope can be calculated using the gradient formula as long as two pairs of coordinates are given. This question provides the slope, hence we can substitute its value into the equation right away.

In slope-intercept form, the equation of a line is given by y= mx +c, where m is the slope and c is the y-intercept. The slope gives us the steepness of the line, while the y-intercept is the y value in which the line cuts through the y-axis (vertical axis).

y= mx +c

Given that slope= [tex]\frac{3}{2}[/tex], m= [tex]\frac{3}{2}[/tex].

Substitute the value of m:

[tex]y=\frac{3}{2}x+c[/tex]

Next, find the value of c by substituting a pair of coordinates.

When x= -4, y= 1,

[tex]1=\frac{3}{2} (-4)+c[/tex]

1= -6 +c

Add 6 to both sides:

c= 1 +6

c= 7

Substituting the value of c:

[tex]\bf{y=\frac{3}{2}x +7 }[/tex]
