If the cost is a function depending in the number of sections, how much will 200 sections cost? a. 7,400 b. 7,439 c. 7,556 d. 7,837

So here we have a function F(x) = y. and you give some of the points (x,y).

this are (10, 409) , (50, 1889) , (125, 4664)

then, if we assume a linear relationship, we could find the slope using the next formula:  

then for the first two points we get:

and the slope between the second and third point is:

So we have the same slope in the two segments, and it's safe to assume that our function is linear. Now we need to find the x-intercept

then F(x) = 37x + b

and F(10) = 370 + b = 409

b = 409 - 370 = 39

So our function is F(x) = 37*x + 39

then if x = 200, F(200) = 37*200 + 39 = 7439.

So the correct answer is B.

an

y = 6x -3y -12

y +3y +12 = 6x

=> . x = { 2y / 3 +2 } this is equation of line in terms of x

=> . if line meets the x-axis the co-ordinates of meeting point would be ( x , 0 )

=> . x = 2 ( 0 ) / 3 + 2

=> . x = 2

so, the point is ( 2 , 0 )

answer: 16

step-by-step explanation: first you would add 6+6 which equals 12 then add 2+2 which equals 4. then add 12 + 4 which is 16.

hope this ^_^
