The parametric equations x = x1 + (x2 − x1)t, y = y1 + (y2 − y1)t where 0 ≤ t ≤ 1 describe the line segment that joins the points p1(x1, y1) and p2(x2, y2). draw the triangle with vertices a(1, 1), b(4, 3), c(1, 7). find the parametrization, including endpoints, and sketch to check. (enter your answers as a comma-separated list of equations. let x and y be in terms of t.)

  see below

Step-by-step explanation:

Filling the given numbers into the given formulas, you have ...

Line AB:

  x = 1 +(4-1)t, y = 1 +(3-1)t

  x = 1+3t, y = 1+2t . . . . . . simplify

Line BC:

  x = 4 +(1-4)t, y = 3 +(7-3)t

  x = 4 -3t, y = 3 +4t . . . . . simplify

Line AC:

  x = 1 +(1-1)t, y = 1 +(7-1)t

  x = 1, y = 1+6t . . . . . . . . . .simplify

it will cost dollar $540

the living room is 3 which means if we divide 325/3 then we get $108

therefore if 1part of the living room cost $108 and 3 costed $325

then total 5part of the room will cost 5*108 which gives $540
