Answer:
The cost of 1kg jam is $7 and the cost of 1kg butter is $4
Step-by-step explanation:
Let jam = x
butter = y
3x + 2y = 29 -----(1)
6x + 3y = 54 -----(2)
(1)×2 ->
6x + 4y = 58 -----(3)
(3)-(2) ->
y = 4
suby=4into(2)
6x + 3(4) = 54
6x = 42
x = 7

Answer:
The new slope is 1
Step-by-step explanation:
The slope of any two points can be found by:

Finding slope of (3,7) (4,9)

Finding slope of (4,9) (5,11)

So, the slope of the line is 2
Now if slope is divided by 2, new slope will be:

So, The new slope is 1
