4x is the proportionality
Let us represent the slots of sweaters with dashes:
_ , _ , _ , _ , _ , _
The first slot has 10 possibilities, the next has 9, the next has 8 and so on.
10 x 9 x 8 x 7 x 6 x 5
= 151200 arrangements
Answer:
x=2, y=1
Step-by-step explanation:
Yes. It's a linear function.
<u>x | y</u>
<u>0| 2(0) = 0</u>
<u>1| 2(1) = 2</u>
<u>2| 2(2) = 4</u>
X-0.9 = 4.5
+0.9 +0.9
x = 5.4
( to get rid of the -0.9 beside the x, u have to do the opposite operation on both sides. if its -0.9, u have to add 0.9 on both sides)
not sure about the first one.
