Answer:

the number is 3

Step-by-step explanation:

seven times a number is equal to 12 more than 3 times the number

7*n = 12+3*n

7n=12+3n

subtract 3n from each side

7n-3n = 12+3n-3n

4n = 12

divide each side by 4

4n/4 = 12/4

n =3

Which statement is true about the discontinuities of the function f(x)?
Leno4ka [110]

Answer:

  (a)  There are asymptotes at x=3/2 and x=-1/3

Step-by-step explanation:

The denominator zeros can be found by factoring:

  f(x) = (x +1)/((2x -3)(3x +1))

Neither of the denominator factors is cancelled by the numerator factor, so each represents a vertical asyptote, not a function hole.

The asymptotes are at the values of x where the denominator is zero:

  2x -3 = 0   ⇒   x = 3/2

  3x +1 = 0   ⇒   x = -1/3

Given F(x)=1/x-4, g(x)=1/6-x. Find f+g(x).
Yakvenalex [24]

\boxed{f(x)+g(x)=\frac{1}{x}-x-\frac{23}{6}}

<h2>Explanation:</h2>

We are given two functions:

f(x)=\frac{1}{4}x-4 \\ \\ g(x)=\frac{1}{6}-x

So, we have to find f(x)+g(x) which is the sum of these two functions:

f(x)+g(x)=\frac{1}{x}-4+\frac{1}{6}-x \\ \\ \\ Let's \ call \ h(x)=f(x)+g(x) \\ \\ Simplifying: \\ \\ h(x)=\left(\frac{1}{x}-x)+(-4+\frac{1}{6}) \\ \\ \\ \\

Finally: \\ \\ \boxed{f(x)+g(x)=\frac{1}{x}-x-\frac{23}{6}}
