comparing rates.. use the formula  d = r * t    where d= distance , r = rate or speed  and t = time  ofc.  :)

Step-by-step explanation:

we know the distance  and the time but not the rate.. find that  r

d/t = r    4/30 = r    = 0.13333333333  this is in Km per minute,   b/c the 4 is Km and the 30  is in minutes.  Units are not to important other than keeping track of what they are.  

Now we can answer the question  can Marlene run 6 Km in 45 mins. b/c we know her rate , or speed,   so at her rate of 0.133333333  Km/min  and using that d = r * t formula  what is her distance in 45 minutes..  so  multiply 45 * 0.133333= 6     so she runs exactly 6 Km in 45 minutes.. so the math answer is yes

find the vertical and horizontal asymptotes of the function f x = 5 x − 1 . to find the vertical asymptote, equate the denominator to zero and solve for . since the degree of the polynomial in the numerator is less than that of the denominator, the horizontal asymptote is .
