If (n+1)!=90×(n-1)!,find n.

Helen [10]

$\displaystyle\bf\\(n+1)!=90\times (n-1)!\\\\(n-1)!\times n\times(n+1)=90\times (n-1)!~~~\Big|~:(n-1)!\\\\n(n+1)=90\\\\n(n+1)=9\times10\\\\n(n+1)=9(9+1)\\\\\implies~~\boxed{\bf n=9}$

Explain the steps when solving 10 h > 2 2h.

Setler [38]

This is an inequality, let's solve this step by step!
10h < (2)(2)h
Step 1 : Simplify both sides of the inequality.
10h < 4h
Step 2 : Subtract 4h from both sides:
10h - 4h < 4h - 4h
6h < 0
Step 3: Divide both sides by 6.
6h/6 < 0/6
h < 0

Answer: h < 0

*Note this should be shown on a number line , but I do not know how to insert one on Brainly, sorry.

Where are the astmptotes for the following function located f(x)=7/x^2-2x-24

ira [324]

Answer:

Hence, the asymptotes of f(x) located at x=6 and x=-4.

Step-by-step explanation:

Since we have given that

f(x)= \frac{7}{x^2-2x-24}

We need to find the asymptotes for the above function:

Asymptotes occur when denominator becomes zero.

x^2-2x-24=0\\\\x^2-6x+4x-24=0\\\\x(x-6)+4(x-6)=0\\\\(x-6)(x+4)=0\\\\x=6,-4
