We have the following functions:
f (x) = x3 - 3x2 - 13x + 15
f (x) = x4 + 3x3 - 8x2 + 5x - 25
f (x) = x3 - 2x2 - x + 2
f (x) = -x3 + 13x - 12
Factoring we have:
f (x) = x3 - 3x2 - 13x + 15 -------> x + 3
f (x) = x4 + 3x3 - 8x2 + 5x - 25 -> x + 5
f (x) = x3 - 2x2 - x + 2 ------------> x - 2
f (x) = -x3 + 13x - 12 -------------> x + 4
Answer:

Step-by-step explanation:
A compound inequality is an inequality that combines two simple inequalities
we are given that

<u>solving</u><u> </u><u>x </u><u>for</u><u> the</u><u> first</u><u> equation</u><u>:</u>

add 4 to both sides:

divide both sides by 4 and since we are dividing both sides by a positive number the inequality won't swap

<u>solving</u><u> </u><u>x </u><u>for</u><u> the</u><u> </u><u>second</u><u> equation</u><u>:</u>

cancel 5 from both sides:

divide both sides by 9 and since we are dividing both sides by a positive number:

therefore by combining the equations we obtain:

hence,
our answer is A)
The other side is 5 hope this helps
Let x be the price of each pen and y be the price of each pencil. From the given, the equations that are described are,
6x + 8y = 8.50
4x + 4y = 5
Solving for x and y simultaneously gives an answer of x = 0.75 and y = 0.5.
Thus, each pen costs $0.75 and each pencil costs $0.50.
