The domain of the rational function in discuss as in the task content is the set of all real number values.
<h3>What is the domain of a rational expression?</h3>
The domain of a rational function or expression is the set of all real values of x, except for that/those which render the function or expression undefined as the case may be.
However, in this scenario, the denominator of the rational function is constant and hence all X-values render the expression defined.
Ultimately, the domain of the expression is the set of all real number values of x.

Answer:
y = -24x + 49
Step-by-step explanation:
y - 1 = -8 ( 3x - 6 )
y - 1 = -24x + 48
+ 1 +1
y = -24x + 49
Answer:
see explanation
Step-by-step explanation:
To find the x- intercepts, set y = 0, that is
2x² - 3x - 5 = 0
To factorise the quadratic
Consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term
The factors are + 2 and - 5
Use these factors to split the x- term
2x² + 2x - 5x - 5 = 0 ( factor the first/second and third/fourth terms )
2x(x + 1) - 5(x + 1) = 0 ← factor out (x + 1) from each term
(x + 1)(2x - 5) = 0
Equate each factor to zero and solve for x
x + 1 = 0 ⇒ x = - 1 ⇒ (- 1, 0)
2x - 5 = 0 ⇒ 2x = 5 ⇒ x = ⇒ (, 0)
Answer:
35.9
Step-by-step explanation:
The "work" is entering the numbers into a suitable probability calculator. A TI-84 calculator will tell you ...
invNorm(0.41,37.6,7.6) = 35.87065818
A score of about 35.9 separates the bottom 41% from the top 59%.

Explanation:
R = D + 12 (1)
D = B + 6 (2)
R = 2*B (3)
Put (3) into (1): 2*B = D + 12 (4)
Rewrite (2) as B = D - 6 and put this into (4): 2*(D - 6) = D + 12
So: 2D - 12 = D + 12
Subtract D from both sides and add 12 to both sides to get: D = 24
