Indicate any restrictions on the variable in the following rational expression, then reduce the rational expression to lowest terms . If it is already in lowest terms, enter the expression in the answer box.

(r - 5)/(r ^ 2 - 25)

Rational expression in lowest terms:

Variable restrictions on the original expresssion:

answer: 33 ( approx)

step-by-step explanation:

since, in the linear regression formula, the slope is the a in the equation y = b + ax ( by comparing it with the general equation of line y = mx + c )

where,

here given table is,

price ($), x   :           18         23       25       29       30       33

pairs sold, y :         16         13         10       8         6       2

so, ,   ,   ,

and   ,

thus, slop of the given line is,

⇒  

⇒   ≈ 33

one fourth of 9% = 2.25%

gavin is correct in saying : the equivalent quarterly interest rate would be

2.25%.

why are you giving so many marks make your marks less and make a question list so that i can understand your question very nicely

step-by-step explanation:

a = (-2, 0)

b= (-4, 0)

c = (-5,2)

d = (-1,2)
