Answer:
-7
Step-by-step explanation:
Given

Required
The first difference
To do this, we simply calculate the difference between the consecutive y-values.
i.e.

So, we have:




<em>Hence, the first differences are -7 (all through)</em>
The answer is B. 2y+3
this is proven by multiplying the divisor of the original question and the solution
<span>cylindrical vase
r=radius </span>cylinder=radius cone
h= height cylinder=height cone
Volume cylindrical vase (V1)= 63 cm³=pi*r² *h
cone
Volume cone (V2)=pi*r² *h
if radius cylinder=radius cone and height cylinder=height cone
then V1=V2
therefore
V2= 63 cm³
the answer is The volume of cone is 63 cm³
I think it’s the third one and the last two. I’m sorry if it’s wrong
Y= -205
Step-by-step explanation:
Y=2-9x x=23
Y=2-9(23)
Y=2-207
Y= -205
