the player runs 3 meters forward and then 3 meters in the opposite direction
Answer:
Third choice
Step-by-step explanation:
The domain of f(x) is the set of all real values except 7, i.e 
and the domain of g(x) is the set of all real values except -3, i.e 
The domain of
is the set of all real numbers x in the domain of
such that
is in the domain of
.
However any numbers that are excluded from the domain of f must also be excluded from the domain of
.
Therefore the correct choice is all real values except x=7 and the x for which f(x) =7

Answer:In mathematics, a real number is a value of a continuous quantity that can represent a distance along a line. The adjective real in this context was introduced in the 17th century by René Descartes, who distinguished between real and imaginary roots of polynomials
Step-by-step explanation:
Answer:
or 
Step-by-step explanation:
To solve the quadratic equation we must factor the expression
Look for 2 numbers that when you multiply them, obtain the result -100 and when you add them, obtain the result -15.
You can verify that these numbers are -20 and 5

Then the polynomial factors are

The zero product property says that if two terms
then
or 
So
