Answer:

- x³ + x² + x - 3

Step-by-step explanation:

(3x³ + 2x - 3) - (4x³ - x² + x)

3x³ + 2x - 3 - 4x³ + x² - x

3x³ - 4x³ + x² - x + 2x - 3

- x³ + x² + x - 3

Answer:

These parallel lines cross 1 line. Because they are parallel they will form the same angles on that line. Therefore, x+50 = 3x-100 since those angles are corresponding angles made by a pair of parallels.

To find x we need to find what value of x gives the same answer for 3x-100 and x+50 since those 2 angles are equal.

x+50 = 3x-100 - now all we need to do is solve for x:

x+50 = 3x-100

50=2x-100

150=2x

75=x

x=75

chad wants to buy some books over the internet. each book costs $10.01 and has a shipping cost of $9.96 per order. if chad wants
Serga [27]
If you would like to find the inequality that shows the maximum number of books that he can buy, you can do this using the following steps:

p ... number of books

$10.01 * p + $9.96 <= $50
10.01 * p + 9.96 <= 50
10.01 * p <= 50 - 9.96
10.01 * p <= 40.04
p <= 40.04 / 10.01
p <= 4 books

The correct result would be <span>9.96 + 10.01p ≤ 50, so p ≤ 4.</span>
