<u>Case 1 :</u>
5 positive x-tiles = 5x
1 positive unit tile = 1
5 positive x-tiles and 1 positive unit tile = 5x + 1
<u>Case 2 :</u>
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.
The ratio in it's lowest form is 7:4
Answer: The chippy brand
Step-by-step explanation: Since 3 bags for the crunchy goodness is 6.30 dollars, we don;t need to worry about that. SO, lets see how much money is 3 bags from the chippy brand.
2.30 x 3 = 6.90
Chippy: $6.90
Crunchy Goodness: $6.30
Now that we compared the Chip brans, its obvious that crunchy goodness is cheaper
The answer is C. They are all no more than £1.10 off,
Answer:
B
Step-by-step explanation:
<em>y</em><em>=</em><em>kx</em><em>+</em><em>m</em>
<em>k</em><em>=</em><em>y2</em><em>+</em><em>y1</em><em> </em><em>/</em><em> </em><em>x2</em><em>+</em><em>x1</em><em> </em>
(3,5) and (7,9)
k=(9-5)/(7-3)=4/4=1
Now we want to find out what <em>m</em><em> </em>is. This is by inserting a point in the equation of the line y=kx+m.
so I'll pick (3,5)
5=1×3+m
m= 2
To check if it's correct we could try it with the other point, (7,9).
9=1×7+m
m=2
Therefor the equation would be. y=1x+2
