By viewing equivalent ratios and rates as deriving from, and extending, pairs of rows (or columns) in the multiplication table and by analyzing simple drawings that indicate the relative size of quantities.
Round 4/3 to the nearest half you should come up with 2/3
The common rule is (x - 1, y + 3) can be used to describe the translation.
Step-by-step explanation:
Step 1:
The point J (-3, -4) becomes
(-4, -1).
In order to write the rule for translation from J to
, we subtract the x coordinate of J from
and subtract the y coordinate of J from
.
The x coordinate 
The y coordinate 
Step 2:
So from the calculations, we get that the x coordinate is subtracted by 1 i.e.
and the y coordinate is increased by 3 i.e.
.
So the common rule is (x - 1, y + 3).
If perimeter is 60 so the side is 60 ÷ 3 = 20
Now we can apply the area formula for triangles;
