Which statement best describes the excluded values of a rational expression?
2 answers:
<h2>Answer:</h2>
Option: B is the correct answer.
B. The number of excluded values of a rational expression cannot exceed the degree of the denominator.
<h2>Step-by-step explanation:</h2>We know that a rational expression is a expression of the form:
where p(x) and q(x) are polynomials.
Excluded value--
The excluded value of a rational expression are the values where the denominator of the expression is zero.
Also, the number of zeros of a polynomial is always less than or equal to degree of the polynomial.
Hence, the number of excluded values of a rational expression cannot exceed the degree of the denominator.

Answer:
The T-shirt lands in the bleachers at a height of 14 feet.
Step-by-step explanation:
The point where they meet is the solution of the simultaneous system of equations:
...........................................(1)
..............................................(2)
From (2),
.................................................(3)
Substituting (3) in (1),
Multiply through by 24 (the LCM of 3 and 8, the denominators of the fractions)
OR
OR
The value of <em>y</em> represents the height.
Substituting for <em>x</em> in (3)
We discard the negative answer.
Hence, the T-shirt lands in the bleachers at a height of 14 feet.
