Given the functions a(x) = 3x - 12 and b(x) = x-9, solve a(b(x)) and select the correct answer below. alb(x) = 3x - 21 alb(x)) = 3x - 39 ab(x)] = 3x - 21 alb(x)) = 3x - 39

idk

step-by-step explanation:

the equation of the parallel line would be y = 2x + 9

step-by-step explanation:

to start we need to find the slope of the original line. we can do that by looking at the coefficient of x, which is 2

since the slope of the original line is 2 and parallel lines have the same slope, we know the new line will also have 2 slope. now we can use that along with the point given in point-slope form to get the find equation.

y - y1 = m(x - x1)

y - 5 = 2(x + 2)

y - 5 = 2x + 4

y = 2x + 9

erica would now have 20 bottles of water because 26-6=20.

i hope this : )
