Answer: A.
Step-by-step explanation:
Answer:
X Y
-2 8
-1 7
0 6
1 5
2 4
3 3
Step-by-step explanation:
We have the equation: x+y=6
We want to get this in the form: y=mx+b (or in this case y=x+b)
To do this we need y to be positive and by itself
So we subtract y from both sides and divide by -1 (we divide by -1 because otherwise y would be negative and that does not fit our template of y=x+b)
Doing this we have
-x+6=y
From here we just plug in numbers -2 to 3 which I will assume you know how to do
X Y
-2 8
-1 7
0 6
1 5
2 4
3 3
-21.8+18.3
or 18.3-21.8
or the answer which is -3.5
Tricky one! Since we are not given any lengths I will use my intuition.
4*4/2 = 8
5*5=25
(25-8)/25 = 17/25 = 68%
Am I right? Is my intuition correct/ please tell me so thanks!
