  We have:
  The generic equation of the line is:  y-yo = m (x-xo)
  The slope is:
  m = (y2-y1) / (x2-x1)
  m = (- 2-0) / (3-0)
  m = -2 / 3
  We choose an ordered pair
  (xo, yo) = (0, 0)
  Substituting values:
  y-0 = (- 2/3) (x-0)
  Rewriting:
  y = (- 2/3) x
  Answer:
  The equation of the line is:
  y = (- 2/3) x

A box's volume is equal to 600 cubic
olga2289 [7]

Answer:

Step-by-step explanation:

Length = x

width = x - 7

height = x - 10

volume = 600 in^3

Volume = L * w * h

600 = x * (x - 7)*(x - 10)

600 = x * (x^2 - 17x + 70)

600 = x^3 - 17x^2 + 70x

x^3 - 17x^2 + 70x - 600 = 0

There is a genius somewhere that could solve this using algebra. The rest of us have 2 choices. We can graph it (see below) or we could use a program that solves it for us. I'll do both for you.

a = 1

b  = - 17

c = 70

d = - 600

There is only 1 real solution: x = 15

L = 15

w = 8

h = 5

That has to be one of the ugliest graphs made. It does into the hundreds of thousands and it still looks like a straight line. Trust me. It's not.
