Think of a strategy that works out best for you.
This is a geometric sequence problem.
You have a sequence of;
2/3, 2, 6, 18, 54
Their common ratio is t1/t0 = 2/(2/3) = 3
Formula for G.P n terms is denoted by
ar^(n-1) = nth term
Where;
a - first term
r - common ratio
n - nth term in the sequence
So the exponential formula is basically that.
Example
To find the 3rd term which is 6
ar^(n-1) = (2/3)(3)^(3-1)
-> (2/3)(3)²
-> (2/3)(9)
-> (2)(3)
-> 6
18^4 this is another way to show an exponent
Hi Grant.
(3x + 5) + (2x - 9) is what we'll start with. Considering we cannot combine variables with numbers, we can only combine like-terms.
3x + 2x; 5 - 9; we result with: 5x - 4
Now, we are left with (5x - 4) - (4x + 3)
Remember to distribute the negative sign to everything to the right.
(5x - 4) - 4x - 3. We are now able to simplify and solve for our answer.
5x - 4x; -4 - 3; we result with x - 7.
Your answer is A.) x - 7.
I hope this helps!
