Natasha_Volkova [10]

The number of tweets that's will be needed to send to get at least 48 people will be at least 9 tweets.

Let the number of tweets be represented by x.

Therefore, based on the information given, the equation to solve the question will be:

12 + (4 × x) ≥ 48

12 + 4x ≥ 48

Collect like terms.

4x ≥ 48 - 12

4x ≥ 36

x ≥ 36/4

x ≥ 9

Therefore, 9 or more tweets will be needed.

Savatey [412]

Answer:

Third choice

Step-by-step explanation:

The domain of f(x) is the set of all real values except 7, i.e x\ne7

and the domain of g(x) is the set of all real values except -3, i.e x\ne -3

The domain of g\circ f is the set of all real numbers x in the domain of f  such that f(x) is in the domain of g(x).

However any numbers that are excluded from the domain of f must also be excluded from the domain of g\circ f.

Therefore the correct choice is all real values except x=7 and the x for which f(x) =7
