(a)
pavan saves = x
his 1st brother saves = x + 4
2nd brother saves = x +4
all together they save = x + x +4 + x + 4
= 3x+8
so
3x + 8 = 26
(b)
3x + 8 = 26
subtract 8 from.both side
3x + 8 - 8 = 26 - 8
3x = 18
divide by 3 both side
3x/3 = 18/3
x = 6
so pavan saves $ 6 each month
The term that is not possible in the domain of a sequence is:
-5.
<h3>What is the domain of a function?</h3>
The domain of a function is the set that contains all possible input values for the function. For a sequence, the domain is the set that contains all the indexes of the terms, starting at 0 and going until the nth term.
For example, suppose we have the following sequence: 3, 5, 7, ...
- The term with index 0 is 3.
- The term with index 1 is 5.
- The term with index 2 is 7.
From what was explained above, which also can be visualized with the example, an index term of a sequence cannot be negative, hence the term that is not possible in the domain of a sequence is:
-5.
Which is the only negative number of the options.

Answer:
The slope is 2.5
Step-by-step explanation:
y = 2.5x + 5 or
y =
5/2x + 5
When x=0, y = 5
When y=0, x = -2
