Three points, A, B, and C exists in space such that B is "between" A and C. It is known that AB=7, BC=4, and AC=9. Are points A,

B, and C collinear? Give a written explanation, supported by mathematical evidence, for your answer.

Two or more points are said to be collinear if they lie on the same straight line.

Given a straight line XY, with a point P on the straight line between point X and Y, then
XP + PY = XY

From the question, it was given that AB = 7 and BC = 4, so if A, B, C are colinear, then
AB + BC = AC
i.e. 7 + 4 = 11

But, from the equation, AC = 9.

Therefore, points A, B and C are not collinear.

F(x)=9xcubed+2xsecond power-x+4 and g(x)=5xcubed-7x+4. What is f(x)-g(x)?
Vlada [557]

f(x) - g(x) = 9 {x}^{3}   + 2 {x}^{2}  - x + 4 - 5 {x}^{3}  - 7x + 4 \\  = 4 {x}^{3}  + 2 {x}^{2}  - 8x + 8

Wayne and Winston are scuba diving and are ascending to the surface. The function y = 30x − 105 represents Wayne’s elevation in
SashulF [63]
First find slope or rate of winston(0,-100) and (3,-16)

slope=(y2-y1)/(x2-x1)
slope=(-16-(-100))/(3-0)=(-16+100)/(3)=84/3=28/1



wane slope or elevation gain
y=mx+b
m=slope or rate of elevaion gain
b=yintercept or starting oint
y=30x-105
slope or rate of change is 30


30 vs 28


wane acends faster than winston

also, the starting point or when x=0 point is the starting point
wane: -105 is start
winston: -100 is start

wane started deeper
so the true statements are
Wayne ascends at a faster speeds
Wayne was deeper when he began ascending
