Yes I do believe that is correct!
Explanation:
The equation is 
Frida started to solve the equation by adding 3 to both sides.
Thus, the equation becomes,
This will not solve the equation.
To solve the equation , we need to divide both sides of the equation by 3.
Thus, the equation becomes,
Dividing we get,
Hence, Frida cannot solve the equation by adding 3 to both sides of the equation. To solve the equation, Frida needs to divide both sides of the equation by 3.
Thus, to solve the equation Frida needs to divide both sides of the equation by 3.
Answer: things do not change
Step-by-step explanation:
i took the test
For the series:
- 5 + ( - 1 ) + 3 + 7 + 11
common difference between the numbers is 4 and a 1 = -5
The series in sigma notation:
4
∑ ( 4 i - 5 )
i =0
A1 = 9 × 1 - 6 = 3
A2 = 18 - 6 = 12
A3 = 27 - 6 = 21
A4 = 36 - 6 = 30.
Step-by-step explanation:
Σ ( 9n - 6 ) , n = 1
An = general term.
let Σ (An) = Σ (9n-6)
An = 9n-6
to determine the terms, plug in the value of n into the general term(An)
If you're asked for the 1st term then n = 1
if you're asked for the 2nd term then n = 2. and so forth.
To find the 1st 4 terms, just plug in 1 up to 4 into n bit by bit.
An = 9n - 6
A1 = 9 × 1 - 6 = 3
A2 = 18 - 6 = 12
A3 = 27 - 6 = 21
A4 = 36 - 6 = 30. done.
write the terms from 1 to 4 like this :
{ A1, A2, A3, A4 } = { 3, 12, 21, 30 }.
