Answer:

The option is: <em>all real values except x = 7 and the x for which f(x) = -3</em>

Step-by-step explanation:

As the domain of f(x) is the set of all real values except 7. So it can be written as follows:

              Domain of f(x) = { x ∈ R | x ≠ 7}

As the domain of g(x) is the set of all real values except -3. So it can be written as follows:

              Domain of g(x) = { x ∈ R | x ≠ -3}

It is a common rule that the domain of a composite function (gºf)(x) will be the set of those input x in the domain of f for which f(x) is in the domain of g.

So, the option is: <em>all real values except x = 7 and the x for which f(x) = -3</em>

Answer:

Team A: 25 players

Team B: 24 players

Step-by-step explanation:

Team A:

to find the total # of players of the team we need to set up a fraction. 5 out out of an unknown number of players is equal to 1/5, so we set it up as:

\frac{5}{x} = \frac{1}{5}

then we cross multiply to get

x*1 = 5*5

x=25 players

Team B

similarly to Team A

\frac{3}{x} = \frac{1}{8}

cross multiply to get

x*1=3*8

x= 24 players

A mother is three times as old as her daughter, and the sum of their ages
garri49 [273]

Answer:

33

Step-by-step explanation:

If m = Mother's age and d = daughter's age, we can make the following equations

m = 3d

m + d = 44

Now, using substitution, we can substitute m for 3d in the second equation:

3d + d = 44, 4d = 44, d = 11

Then, we can plug d into the first equation: m = 3(11) = 33

A circular mirror has a diameter of 12 inches. And a circular frame that is 3 inches wide surrounds the mirror. What is the comb
Lapatulllka [165]

Answer:

254.5 in.^2

Step-by-step explanation:

diameter of mirror = 12 in.

radius of mirror = diameter/2 = 13 in. / 2 = 6 in.

frame width = 3 in.

radius if combined mirror and frame = 6 in. + 3 in. = 9 in.

A = (pi)(r^2)

A = 3.14159 * (9 in.)^2

A = 3.14159 * 81 in.^2

A = 254.5 in.^2
