BRAINLIEST ANSWER GIVEN Solve inequality and write interval notation.<img src="https://tex.z-dn.net/?f=5x%2B4%5Cleq%20x-8" id="T

Anuta_ua [19.1K]

Answer:

$x\leq -3$

Step-by-step explanation:

I can't write interval notation on Brainly but I can solve the inequality.

$5x+4\leq x-8$

Subtract $x$ from both sides

$4x+4\leq -8$

Subtract 4 from both sides

$4x\leq -12$

Divide both sides by 4

$x\leq -3$

Please help! Solve the following:

mihalych1998 [28]

Answer:

n=10.

Step-by-step explanation:

$\frac{45}{n^{2}-3n-4 }$ - $\frac{3}{n-4}$ = $\frac{2}{n+1 }$

$\frac{45}{n^{2}-3n-4 }$ - $\frac{3(n+1)}{(n+1)(n-4)}$ = $\frac{2(n-4)}{(n+1)(n-4) }$

$\frac{45}{n^{2}-3n-4 }$ - $\frac{3n+3}{n^{2} -3x-4}$ = $\frac{2n-8}{n^{2} -3x-4 }$

45-3n-3=2n-8

45-3+8=5n

n=50/5=10

LCM = 2 x 2 x 3 x 5 = 60
The 60th visitor will be the first to get both.

elixir [45]

The appropriate method to use in solving the given question is permutation. Then, the numbers of ways to arrange the buttons is 1320 ways.

In the given question, the order of arrangement is important, so that the number of ways that Fiona could order the buttons can be determined by permutation method.

i.e $_{n}$ $P_{r}$ = $\frac{n!}{(n - r)!}$
