5 positive x-tiles and 1 positive unit tile to represent 5x + (– 1) 2 negative x-tiles and 6 positive unit tiles to represent –2

snow_lady [41]

Case 1 :

5 positive x-tiles = 5x

1 positive unit tile = 1

5 positive x-tiles and 1 positive unit tile = 5x + 1

Case 2 :

2 negative x-tiles = -2x

6 positive unit tiles = 6

so, 2 negative x-tiles and 6 positive unit tiles = -2x+6

We see that Gracia has represented the 1st case as 5x+(-1), which should be 5 positive x-tiles and 1 negative unit tile.

Hence the statement : 5 positive x-tiles and 1 positive unit tile to represent 5x+(-1) , explains Gracia's error.

Complete the following table using the equation 2x-3=y.

denis23 [38]

y = 2x-3

a) x=1

y= 2 x 1 -3

y= 2-3

y= -1

b) x=2

y= 2 x 2 - 3

y= 4-3

y = 1

c) x = 3

y = 2 x 3 -3

y = 3
