Find the number of palindromes between 10,000 and 99,999 that are divisible by 25.
( a palindrome is a number that reads the same forwards and backwards

52025 palindromes between 10,000 and 99,999 that are divisible by 25.

Step-by-step explanation:

Given  : Numbers between 10,000 and 99,999 .

To find : Find the number of palindromes between 10,000 and 99,999 that are divisible by 25.

Solution : We have given numbers between 10,000 and 99,999 .

Palindrome Numbers :  that read the same backwards and forwards.

Example : 17371.

Numbers that divisible by 25 : numbers end with 0 , or 5

Example : 25 , 100 , 75

We can see from given numbers  palindromes between 10000 and 99999 are of the form abcba ,

Where,  c can be 0 to 9

Like  : 55555 , 52025, 52125 ,52225 , 52325 so on

Therefore,  52025 palindromes between 10,000 and 99,999 that are divisible by 25.

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.

solving with completing the square

b

step-by-step explanation:

the equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (0, 4) and (x₂, y₂ ) = (3, - 5) ← 2 points on the line

m = = = - 3

with m = - 3 and (a, b) = (3, - 5), then

y - (- 5) = - 3(x - 3), that is

y + 5 = - 3(x - 3) → b
