Answer:

Step-by-step explanation:

If you mean

27^4 - 9^5·3^9 = -1161730026

it has no factors of 5, so cannot be divisible by 25.

If you mean ...

(27^4 -9^5)/3^9 = ((3^3)^4 -(3^2)^5)/3^9 = 3^10(3^2 -1)/3^9 = 3(9-1) = 24

it is not divisible by 25, either.

I need help with this problem down below

Misha Larkins [42]

Answer:

$y = 4$

Step-by-step explanation:

Given:

$y = \frac{7x + 1}{3x - 6}$ ,

To find the value of y, let's find x by solving 3x = 15.

3x = 15

Divide both sides by 3

x = 15/3

x = 5

Plug in the value of x into $y = \frac{7x + 1}{3x - 6}$

$y = \frac{7(5) + 1}{3(5) - 6}$

$y = \frac{35 + 1}{15 - 6}$

$y = \frac{36}{9}$

$y = 4$
