Start at 4 on the y azures and go down 1 and over 3
Answer:
never
Step-by-step explanation:
Cannot be factored
x² - 6x - 8
x² breaks down into x and x
8 breaks down into 1 and 8, 2 and 4, 4 and 2, or 8 and 1.
(x+4)(x-2) = x² + 2x - 8
(x-4)(x+2) = x² - 2x - 8
(x-4)(x-2) = x² - 6x + 8
(x+4)(x+2) = x² + 6x + 8
We know that the mixture has 14 mm of ink. Of these, 35% are blue pigment, hence the mixture contains 4.9 mm of blue ink. Ink A contains 10%*4mm=0.4mm of blue ink. The difference, 4.5 mm of blue ink must have come from ink B. Thus ink B contains 4.5 mm of blue ink and is in total 10mm. After that, we can calculate the percentage; we divide 4.5/10=0.45 and this is the ratio of blue ink to total ink (in Ink B). If we transform it to percentages it is 45%
