Divide the price by amount to find out how much each costs. multiply that by 9. 4 (divided by) 8 = .5, or 50cents. each apple is 50cents. multiply .50 by 9. It costs 4.50. Hope this helps
7*-4= -28 +4-12/2
-24-6
=-30
X would be 90° ... every x is 90°
It should be B
Calculate the slopes using the change of y over the change in x
-2/2=-1
That’s the only option with a slope of -1
Given:
and
where
.
To find:
The explicit formula for the given recursive formula.
Solution:
We know that recursive formula of an AP is:

Where, d is the common difference.
We have,

Here, d=9.
The first term of the AP is
.
The explicit formula for an AP is:

Substituting
and
, we get



Therefore, the required explicit formula for the given sequence is
.
