Nine
Correct
Ten
The only way I have of solving any of these is either to graph them, or solve them as cubics.
This one is graphed. The choice is C. All are real and 2 are the same. See graph below.

Using Pascal's triangle, the fifth line is 1 5 10 10 5 1
So the answer should be 5p^4q
Twelve
Use Synthetic Division
2 || 1 2 - 5 -6
2 8 6
=====================
1 4 3 0
So the quadratic that's left of this division is
x^2 +4x + 3 =0 for the roots. Factor
(x +3)(x + 1)
These equal zero
x + 3 = 0
x = - 3
x + 1 =0
x = - 1
===============
Answer: Roots (-3, 0)(-1 , 0)
Answer: -3,-1,2

Use synthetic division on all of them. Start out with trying to find -1 as a root. The one that works is C. Then you try -2 also using synthetic division. It also turns out to be a solution for the quartic. What is left over is x^ + 1 which does not factor in the reals.
- 1 || 1 3 3 3 2
-1 -2 -1 -2
=======================
1 2 1 2 0
-2 || 1 2 1 2
-2 0 -2
===================
1 +0 1
The left over is x^2 + 1 = 0 The roots of this are +/- i which is not in the real number system.
Answer: C
Answer:
$122.89
Step-by-step explanation:
The two number you have in this equation are 108.75 and 13% (or .13)
first you want to multiply 108.75 to .13
108.75 * .13 = 14.1375
Now, you add 14.1375 to 180.75 and round to the nearest hundredth
180.75+ 14.1375=122.8875
$122.89
Did u ever find out the answer to this cuz i have the same question
Answer:
True
Step-by-step explanation:
To solve this type of problem the most efficient method is to take the ordered pair and introduce it into the inequality, if this is satisfied then the point belongs to the inequality, if the point is not satisfied it does not belong to the inequality.
We have the following inequality
Then we introduce the ordered pair (-1, -3) into the inequality.
-4 is less than -3, therefore the inequality is met and the ordered pair (-1, -3) is an inequality solution
THE affirmation is True
