Answer:(a) Co-ordinate rule is and
(b) Co-ordinates of B' and C' are and respectively.
Step-by-step explanation:
(a)
Here, the co-ordinates of A are translated to A'.
For the co-ordinates A and A', and
So, x value of A has shifted to right by 6 units and y value of A has shifted 8 units down.
Hence, the co-ordinate rule that maps ΔABC onto ΔA'B'C' is:
and .
(b)
Using the co-ordinate rule, we can find the co-ordinates of B' and C'.
For B, and .
So, of B' is
And, of B' is .
Therefore, co-ordinates of B' are .
For C, and .
So, of C' is
And, of C' is .
Therefore, co-ordinates of C' are .

Answer:
x+11=79
Step-by-step explanation:
To Match
To isolate -1 we need to subtract 2m from both sides
2m - 1 = 3m (SUBTRACT 2m)
To isolate 1 we need to subtract m from both sides
2m = 1 + m (SUBTRACT m)
To isolate m we need to add 1 from both sides
m - 1 = 2 (ADD 1)
To isolate m we need to subtract 2 from both sides
2 + m = 3 (SUBTRACT 2)
To isolate m we need to add 2 from both sides
-2 + m = 1 (ADD 2)
To isolate m we need to subtract 1 from both sides
3 = 1 + m (SUBTRACT 1)

Hope this helps.
Answer:
a) 0
b) 4.5
c) 3
d) 6
Step-by-step explanation:
Formula: 3x + 4y = 12
The questions contains the values of x. So here's an example of:
d) x = -4, y = ?
Using the formula: 3(-4) + 4y = 12
-12 + 4y = 12
4y = 24
y = 6
Do the same for the others!
