The total should be 287.59. You add the numbers (127.12+94.50+65.97) and it should equal to that.

Triangle ABC with vertices A(-2, -3), B(5, -1), and C(2, 2) is translated by (x,y) → (x - 1, y + 2). Then the image, triangle A'
Elan Coil [88]

Answer:

  • A"(-1, -2)
  • B"(6, 0)
  • C"(3, 3)
  • (x, y) ⇒ (x+1, y+1)

Step-by-step explanation:

Translation vectors add, and the addition is commutative and associative.

__

The first translation adds (-1, 2) to the original coordinates. The second translation adds (2, -1) to the original coordinates. The two translations together add ...

  (-1, 2) +(2, -1) = (-1+2, 2-1) = (1, 1)

to the original coordinates.

The single rule representing this translation is ...

  (x, y) ⇒ (x +1, y +1)

Then the doubly-translated coordinates are ...

  A(-2, -3) ⇒ A"(-1, -2)

  B(5, -1) ⇒ B"(6, 0)

  C(2, 2) ⇒ C"(3, 3)

In point A:

An order of 5 items shall be placed in a total of 6 different ways.  

(w for cars and ts and tricycles to be used)

\to 5w=20 wheels\\\\\to  4w+1t= 19 wheels\\\\\to  3w+2t=18 wheels\\\\\to  2w+3t=17 wheels\\\\\to  1w+4t= 16 wheels\\\\\to  5t=15 wheels\\\\

In point B:

2 waggons so more tyres would be required if they ordered any more waggons.  

work: \\\\ \to  2 \times 4=8 \\\\  \to 3 \times 3=9 \\ \\  \to 8+9=17

Write an equation for the line that connects A (-4,8) and B (6,3)
Mazyrski [523]

Answer:

7y+5x=76

Step-by-step explan

A (-4,8) and B (6,3)

First find the slope;

m= (y2-y1)/(x2-x1)

m=(3-8)/(3+4)

m=-5/7

now using equation of line

y-y1= m(x-x1)

y-8=-5/7 (x+4)

y-8=(-5x+20)/7

7(y-8)= -5x+20

7y-56=-5x+20

7y+5x=20+56

7y+5x=76
