Answer:

  • one-story: 10 doors
  • two-story: 13 doors

Step-by-step explanation:

Let o and t represent the numbers of doors in a one-story and a two-story house, respectively.

  2o +t = 33 . . . . . . . . west-side doors

  8o +t = 93 . . . . . . . . east-side doors

__

  6o = 60 . . . . . subtract the first equation from the second

  o = 10

  2(10) +t = 33 . . . . substitute for o in the first equation

  t = 13 . . . . . . . . subtract 20

__

Each one-story house has 10 doors, and each two-story house has 13 doors.

can you give a description of the relationship between the years since the tree was transplanted and its height in inches? if so
brilliants [131]

The relationship between the years since the tree was transplanted and its height in inches is linear and represented graphically by a line with positive slope and positive y-intercept

Step-by-step explanation:

Their is a linear relation between the years since the tree was transplanted and its height in inches because

  • The tree has a constant rate of increasing of its height per year
  • Assume that the initial height of the tree when it planted is b inches
  • Its height increases m inches per year
  • Its height (y) after x years can be expressed in the formula y = m x + b

y = m x + b is the form of the linear equation, where

  • m is the slope of the graph of the equation
  • b is the y-intercept (value y at x = 0)

The relationship between the years since the tree was transplanted and its height in inches is linear represented graphically by a line with positive slope and positive y-intercept
