Step-by-step explanation:

hello :

the point-slope formula is :

y - y_1 = m(x - x_1) the point is A(x_1 , y_1 ) , m : the slope

in this exercice : x_1 = 6 y_1 = 8 m = -2

so : y - 8 = -2(x - 6) ...an equation for this line .

Vlad [161]

Answer:
n = 3.68

Explanation:
We know that:
1 mg is equivalent to 0.0001 dag
To convert 38600 mg to dag, we will simply use cross multiplication as follows:
1 mg ..............> 0.0001 dag
38600 mg ......> n

n = (38600*0.0001) / 1
n = 3.68

Hope this helps :)

Answer:

Step-by-step explanation:

25=mean of (5th+6th value)

25=1/2*(2x-8+2x+10)

25=1/2*4x+2

4x+2=50

4x=48

x=12
