3x + 19 = 10
because X = - 3
Answer:
3n^2+n-2
Step-by-step explanation:
Coefficient is the number that we multiply an expression that contains a variable. In all the expressions above the variable is n.
Some examples:
Coefficient of n^2 is 1.
Coefficient of n in n^2+2n+1 is 2.
Solution:
In 5n^2+6n-1 the Coefficient of n is 6.
In 2n^2+5n+1 the Coefficient of n is 5.
In 40^2 - n +9 the Coefficient of n is - 1.
In 3n^2 +n - 2 the Coefficient of n is POSITIVE 1.
We tend to not write 1*n because 1*n=n.
Answer:
- 2
Step-by-step explanation:
Using the term- to - term rule of subtract 5
This means to find a term in the sequence, subtract 5 from the previous term.
Given a(1) = 13, then
a(2) = a(1) - 5 = 13 - 5 = 8
a(3) = a(2) - 5 = 8 - 5 = 3
a(4) = a(3) - 5 = 3 - 5 = - 2
The fourth term is - 2
