In a survey of 400 members of a local sports club, 200 members indicated that they plan to attend the next Summer Olympic Games, 120 indicated that they plan to attend the next Winter Olympic Games, and 80 indicated that they plan to attend both games. How many members of the club plan to attend (a) At least one of the two games? members (b) Exactly one of the games? members (c) The Summer Olympic Games only? members (d) None of the games? members

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

hello from mrbilldoesmath!

answer:   x (x+6)^2, choice b

discussion:

factor x out of the equation:

x^3 + 12x^2 + 36x = x (x^2 + 12x + 36).

note that 6+6 = 12 and 6*6 = 36 so the above factors into:

x (x+6)^2

which is choice b
