The length of a rectangle is 5in more than 3 times it's width . the quadratic function f(x)=x(3x+5) represents the area of the rectangle in terms of its width . what is a reasonable domain of the function?

12

step-by-step explanation:

12 + 5 = 17

12x2=24

24-7=17

i only know the sequence of arithmetic it adds the first is 5+4 then it goes up as it adds to then it is 9+5 then 14+6 then to 20+7 and so on. 5,9,14,20,27,35.

step-by-step explanation:

y = 3x+4

step-by-step explanation:

to find the slope

slope = (y2-y1)/ (x2-x1)

    = (-8-4)/ (-4-0)

    = -12/-4

  = 3

using the slope intercept form of a line

y= mx+b

we know the slope is 3

we know the y intercept is 4 ( the point where it crosses the y axis or x=0)

y = 3x+4
