Bob purchased a new more efficient European weed whacker that uses gasoline at a rate of 0.75 quarts per hour. Write an equation to represent the relationship between x, the number of hours the weed whacker is used, and y, the number of gallons of gasoline used. (Hint: 4 quarts equals 1 gallon) Round your answer to the thousandths place.

answer: c.  

step-by-step explanation:

mixtures containing substances that get attracted to magnet can be separated using a magnet. we can separate iron from a mixture of sand and iron, as only iron attracts to the magnet.

since we know that the two functions are equal, f (x) = g

(x), therefore when we equate the two equations the result should be similar to

3x = x – 4:

a. f(x) = 3x, g(x) = x – 4

equating the two functions:

3x = x – 4             (correct)

so we now got our answer (a)
