Solve the inequality. (enter your answer using interval notation.) (x(squared) + 6x − 7)/ (7x(squared) − 46x − 21) > 0

Solution -

⇒

⇒

⇒ (x-1)(x+7) > 0 and (x-7)(7x+3) > 0          (In order to make the whole polynomial +ve, both numerator and denominator have to be +ve )

⇒ (x-1)>0 and (x+7)>0 or  (x-1)<0 and (x+7)<0    

                                 and    (either both of the polynomials are +ve or -ve)

   (x-7)>0 and (7x+3)>0  or  (x-7)<0 and (7x+3)<0

⇒ x > 7 , x < -7 , -3/7 < x < 1

Answer

fahrenheit

step-by-step explanation:

fahrenheit is more precise than celsius. the ambient temperature on most of the inhabited world ranges from -20 degrees fahrenheit to 110 degrees fahrenheit—a 130-degree range. on the celsius scale, that range is from -28.8 degrees to 43.3 degrees—a 72.1-degree range. this means that you can get a more exact measurement of the air temperature using fahrenheit because it uses almost twice the scale.
