Y = mx + c (m = gradient, c = y-intercept)
y = -2x + c
2 = (-2 x 6) + c
2 = -12 + c
2 + 12 = c
c = 14

y = -2x + 14

How would the expression x^3-8 be rewritten using difference of cubes

LUCKY_DIMON [66]

Answer:

(x - 2)(x² + 2x + 4)

Step-by-step explanation:

A difference of cubes factors in general as

• a³ - b³ = (a - b)(a² + ab + b² )

note 8 = 2³ = 8 ⇒ b = 2 , with a = x

Hence

x³ - 8

= x³ - 2³

= (x - 2)(x² + 2x + 2²) = (x - 2)(x² + 2x + 4)

Answer:

120 people [see below]

Step-by-step explanation:

48 out of 120 people like baseball.

That is about 48/120 = 0.4 [40%]

Now, 3/5th of THOSE, play baseball, so

0.4 * 3/5 = 0.4 * 0.6 = 0.24 [24%].

Thus, we have seen that around 24% of total people taken would play baseball.

Now, we take 500 people, so 24% of them would be expected to play baseball.

That is 0.24 * 500 = 120 people

Pile Y has the greater mean number of pages per book because it is 5 books less than pile W.

<h3>How to calculate greater mean number of pages?</h3>

From the complete information, we can deduce that the number of each pile of book is given as follows:

Red books = 10 × 5 = 50 red books.

Blue books = 5 × 5 = 25 blue books.

Therefore, total books in pile W = 50 + 25 = 75 books.

Mathematically, the mean for each pile can be calculated by using the following formula:

Mean = [F(x)]/n

Mean = 75/10

Mean = 7.5.

Red books = 10 × 5 = 50 red books.

Mean = [F(x)]/n

Mean = 50/5

Mean = 10.

In conclusion, pile Y has the greater mean number of pages per book because it is 5 books less than pile W.
