Answer:-5/2

Step-by-step explanation:

When there are two points given like above use this formula.

y2-y1/x2-x1

(The 1 and 2 is gonna be on the bottom right. It represents the number of y and x as there is two sets of (x,y)

Answer:

m = ( - 5/2)

Step-by-step explanation:

(-9,10)  , (-7,5)

m = (y₂ - y₁)/(x₂-x₁)

  = (5 - 10) / [-7 -(-9) ]

  = (5 - 10) / [-7 + 9 ]

   =  -5/2

ABC is a straight line.The length of AB is four times the length of BC.AC=75
bearhunter [10]

Answer:

AB = 60

Step-by-step explanation:

Given AC = 75 and AB = 4BC, then

AB + BC = AC, that is

4BC + BC = 75

5BC = 75 ( divide both sides by 5 )

BC = 15

Thus

AB = 4BC = 4 × 15 = 60

Round to the nearest tenth

<em>Note: I am assuming we have to determine the value of the side 'x'.</em>

Answer:

The value of x = 8.1 units

Step-by-step explanation:

<em>Note: I am assuming we have to determine the value of the side 'x'.</em>

Given

Angle Ф = 32°

To determine:

x = ?

Using the trigonometric ratio

tan Ф = opposite / adjacent

here

Ф = 32°

opposite to angle 32°  = x

adjacent to angle 32° = 13

Therefore,

substituting adjacent = 13, Ф = 32°, opposite = x in the equation

tan Ф = opposite / adjacent

\tan \left(32^{\circ \:}\right)=\frac{x}{13}

\:x\:=\:13\:\times tan\:32^{\circ }\:

x = 8.1 units      tan 32° = 0.62

Therefore, the value of x = 8.1 units

Hi

3*5000 +X*2500 = 25 000

15 000 + 2 500X = 25 000

                2 500X = 25 000 - 15 000

                       2 500 X = 10 000

                               x = 10 000 / 2 500

                                 X = 100/25

                                   X = 4

You need 4 post for  B

3*5000 + 4* 2 500 =  15 000 + 10 000 = 25 000
