$f(x)=\dfrac{1}{x^2-3}\\\\a)\ f(3)\to\text{put x=3 to the equation of the function f}\\\\f(3)=\dfrac{1}{3^2-3}=\dfrac{1}{9-3}=\dfrac{1}{6}\\\\Answer:\ \boxed{f(3)=\dfrac{1}{6}}\\\\b)\ f(2+h)\to\text{put x=2+h to the equation of a function f}\\\\f(2+h)=\dfrac{1}{(2+h)^2-3}\ \ \ |\text{use}\ (a+b)^2=a^2+2ab+b^2\\\\=\dfrac{1}{2^2+2(2)(h)+h^2-3}=\dfrac{1}{4+4h+h^2-3}=\dfrac{1}{h^2+4h+1}\\\\Answer:\ \boxed{f(2+h)=\dfrac{1}{h^2+4h+1}}$

Can anybody help me?

lakkis [162]

You know that 6x+3 equals 45 because the two sides are equal. So you first put the equation 6x+3=45. Then you use the subtraction property of equality and subtract 3 from both sides. This gives you 6x=42. Then you divide 6 from both sides to get you final answer, x=7

Use the pattern below for questions 6 - 8.

Yuliya22 [10]

Answer:

See below

Step-by-step explanation:

<u>The sequence given</u>

6, 19, 58, 175

<u>We see the pattern: triple the previous term plus 1</u>

2) 19 = 6*3 + 1
3) 58 = 19*3 + 1
4) 175 = 58*3 + 1

<u>Next two terms</u>

5) 175*3 + 1 = 526
6) 526*3 + 1 = 1579

<u>Following two terms</u>

7) 1579*3 + 1 = 4738
8) 4738*3 + 1 = 14215
