I think its 13
bcz I just added them all up and got the answer 13
72kg - 54kg
180kg - xkg
cross multiply
72 · x = 180 · 54
72x = 9720 |divide both sides by 72
x = 135
Answer: 135kg.
You know this when the two values (x and y) are inversely proportional to each other by their product being constant (always remaining the same). This means when x increases y will decrease.
Hope this helped :)
Yes it is because it doesn't have any outliers
(4,7)(0,7)
notice how ur points have the same y values....this means this is a horizontal line with a slope of 0.
equation is : y = 7...or y = 0x + 7...but we need it in standard form...
0x + y = 7 <== standard form
