the sum of two numbers is zero. when 15 times the smaller numbers is added to 10 times the larger, the result is 1. find the two
1 answer:
We have two numbers say a, b. And a system of equations.
It looks a bit intimidating but it's actually very easy.
Instead of term a + b in the second equation we can say it's zero because the first equation describes a + b as being equal to 0.
So,
The above equation is not true therefore numbers a and b do not exists in the real number domain.
No solution.

Answer:
B)
Step-by-step explanation:
To find this recursive formula, we need to look at the relationship between each term in the sequence.
When looking at n=1 and n=2, we can see that we have 5 and 11.
We have to find a pattern between each term in the sequence. If we double 5, which is the previous term, and add 1, we get 11.
Lets see if this works for the next term, 23
First, lets double 11 = 22
Now add 22+1=23. We got the right term. Lets test it again
23*2=46
46+1=47
And now the last term
47*2=94
96+1=95
As you can see doubling the previous term and adding 1 works for all of these terms.
when written as a recursive formula, it would be , which is B
