Apure acid measuring x liters is added to 300 liters of a 20% acidic solution. the concentration of acid, f(x), in the new substance is equal to the liters of pure acid divided by the liters of the new substance, or . which statement describes the meaning of the horizontal asymptote? the greater the amount of acid added to the new substance, the more rapid the increase in acid concentration. the greater the amount of acid added to the new substance, the closer the acid concentration is to one-fifth. as more pure acid is added, the concentration of acid approaches 0. as more pure acid is added, the concentration of acid approaches 1.

it's d.

step-by-step explanation:

because: -1(4x + 1y) +2 (1x-3y) distribute each number into the parenthesis.

then you would get: -4x - 1y + 2x -6y combine like terms

and get: 2x -7y

hope my answer has you if not then i'm sorry.

109 is the nearest whole number/final answer! : )

, and

for

step-by-step explanation:

we can analyze the pattern at which the terms increase. let us denote , , , so that we can call

note the following:

the pattern: to get the next term value, we just add the next term number (e.g. 1st, 2nd, to the previous term value (term values are the given numbers in the question, 1, 3, 6, 10, 15,

from , to get to , we add

from , to get to , we add

etc.

we need to form a recursive formula, a formula that has the next term as a function of the previous term. so a possible recursive formula can be

, and for

b. f(x) = –√x + 3this is the correct answer
