Answer:

B. y= 2x–15

Step-by-step explanation:

The equation that represents the line that passes through the points (8, 1) and (10,5) is y= 2x–15

"x" is found on the left hand side of the bracket and "y" is found on the right hand side of the bracket :)

(8, 1) and (10, 5)

x in the first bracket is 8 and x in the second bracket is 10.

y in the first bracket is 1 and y in the second bracket is 5.

When this equation is applied to find the value for y we get:

y= 2x-15

y= 2(8)-15

y= 16-15

y= 1

y= 2x-15

y= 2(10)-15

y= 20-15

y= 5

We got back the values of y and this means that the equation was correctly chosen and the answer is correct :)

Find the sum of all positive integers less than 200, which:
Allushta [10]

Answer:

3900

Step-by-step explanation:

We want the sum from 5 to 195

5, 10, 15, 20,......195

an = 5 + 5(n-1)  since we can write this as an arithmetic sequence, adding 5 each time

The sum of the terms of an arithmetic sequence is given by

Sn = n/2 [2a1 + (n - 1)d],  

where d is the common difference of 5 and n is the term we want to add to

195/5 = 39  so it is the 39th term

s39 =39/2 [2*5 + (39-1)*5)]

s38 = 19.5[10+38*5]

        =19.5*[10+190]

          19.5*200

          =3900
