The following problem refers to strings in A, B, ..., Z.
1 answer:
Answer: 676
Step-by-step explanation:
The total number of letters in English alphabet {From A to Z} = 26
We assume that the repetition of letters is allowed.
If we fix H at the first position , then the number of ways to make three-letter strings that begin with H is given by :-
Hence, the number of ways to make three-letter strings that begin with H is 676.

Answer:
slope is 2
Step-by-step explanation:
Find two points that can be used.
(0,4) (2,8)
Use the slope formula and plug in the numbers
=2
Step-by-step explanation:
To solve a system of equations, we can add the two equations and solve for one of the remaining variables -- let's try to eliminate the variable when we add the two equations together.
Right now, there's a term in the first equation, and a
term in the second equation, so if we add those together, we'll be able to eliminate the
variable altogether and solve for
.
However, when we also have a term in the first equation and
term in the second equation, so adding these together will also eliminate the
term, leaving a
on the left-hand side of the equation.
If we add the two numbers on the right side of the equation, we get , which does not equal
, meaning there are no solutions to this system of equations.
