|9x - 9| = 36
To solve for the first solution, simply disregard the absolute value signs.
9x - 9 = 36
Add 9 to both sides
9x = 45
Divide both sides by 9
x = 5
To find the second solution, disregard the absolute value signs and change 36 to -36
9x - 9 = -36
Add 9 to both sides
9x = -27
Divide both sides by 9
x = -3
Now, we need to find the sum of these two solutions.
5 + (-3) = 5 - 3 = 2

Find the mean of 9, 1, 8, 3, 2, 1 graphically.
Answer: 4
Step-by-step explanation:
Mean means to add up the values and divide it by the number of values there is so 9 + 1 + 8 + 3 + 2 + 1 = 24, then 24 / 6 is 4.

What are the solutions of the equation x4 – 5x2 – 36 = 0? Use factoring to solve. x = ±2 and x = ±3 x = ±2i and x = ±3 x = ±2 and x = ±3i x = ±2i and x = ±3i
Answer:
[tex]x=\pm 3\text{ or } x=\pm 2i[/tex]
Step-by-step explanation:
So we have the equation:
[tex]x^4-5x^2-36=0[/tex]
Let's let u equal x² so:
[tex]u^2-5u-36=0[/tex]
Factor. We can use -9 and 4. So:
[tex]u^2+4u-9u-36=0[/tex]
From the first two terms, factor out a u.
From the last two terms, factor out a -9. So:
[tex]u(u+4)-9(u+4)=0[/tex]
Grouping:
[tex](u-9)(u+4)=0[/tex]
Zero Product Property:
[tex]u-9=0 \text{ or } u+4=0[/tex]
On the left, add 9. On the right, subtract 4:
[tex]u=9\text{ or } u=-4[/tex]
Substitute back u:
[tex]x^2=9\text{ or } x^2=-4[/tex]
Take the square root:
[tex]x=\pm 3\text{ or } x=\pm 2i[/tex]
And we're done!
Our answer is the Second option.

Answer:
The pattern is that each time, 8 is added. The next 2 numbers are 47, 55.
Step-by-step explanation:
7+8=15
15+8=23
23+8=31
31+8=39
39+8=47
47+8=55
547 and 14 and 7658 - 7000 = 658 - blank = 98 -98 = 0 what is the answer
Solution :
7658 - 7000 = 658 - blank
658 = 658
So here, blank is 0.
547 - 7000 = 658 - blank
-7111 = 658 - blank
Blank = 7769
14 - 7000 = 658 - blank
- 6986 = 658 - blank
Blank = 7644

Answer: The length of a side of the square is given by x
The length of a side of the equilateral triangle is given by x=1
Given is : The perimeter of a square is equal to the perimeter of an equilateral triangle.
Perimeter of square is given as 4 x side.
Perimeter of equilateral triangle is given as 3 x side.
So, we will make both equal.
As x = 1 for triangle, the equation becomes:
4x=3
so x=3/4

Point A is at (1,5) and point C is at (-5, – 7).
Find the coordinates of point B on AC such that AC is 6 times as long as AB.
Answer:
(0,3)
Step-by-step explanation:
This is a problem from affine geometry, so doesn’t need any concept of distance that mixes x and y coordinates. We can just take each coordinate separately.
(1,5),(−5,−7),(,),=6
Usually in these sorts of problems with unknown B we’re given the ratio AB:BC; here we have the slightly unusual and easier AB:AC.
The difference of the given points −=(6,12) .
Since =6 we know −=16(−)=(1,2)
So =−(1,2)=(1,5)−(1,2)
=(0,3)
A person is trying to quit chewing gum. They decide they will have 64 pieces in week 1, but each week have half as many as the week before. The function f represents the number of pieces of gum they will have in week n. What is a reasonable domain for this function? Explain your reasoning.
Function is missing.
It is;
f(n) = ½⋅f(n − 1) for n ≥ 2
Answer:
Domain for this function is;
n ≥ 1
Step-by-step explanation:
We are told They decide they will have 64 pieces in week 1,
Thus;
f(1) = 64
From the function given;
f(n) = ½⋅f(n − 1)
So;
f(2) = ½•f(2 - 1)
f(2) = ½•f(1)
f(2) = ½ • 64
f(2) = 32
Also;
f(3) = ½•f(3 - 1)
f(3) = ½•f(2)
f(3) = ½ × 32 = 16
Looking at the steps, they follow a general pattern of;
f(n) = 64•½^(n - 1) for n ≥ 1
Thus, the domain for the function for n weeks after the first one is n ≥ 1

Karis receives $90000 per year working as a manager. She spends 15% every 3 month on her daughters college tuition. Write a function rule for the amount of money that Karis still has as a function of time in month
Answer:
[tex]f(m) = 90000 - 0.05m[/tex]
Step-by-step explanation:
Given
[tex]Base\ Amount = \$90000[/tex]
[tex]Spending = 15\%[/tex] -- every 3 months
Required
Determine the function that shows her monthly balance:
Represent month with m
If she spends 15% every 3 months;
Then
She spends 5% every month
i.e.
[tex]monthly = \frac{15\%}{3}[/tex]
[tex]monthly = 5\%[/tex]
If [tex]1\ month = 5\%[/tex]
Then
[tex]m\ months = 5\% * m[/tex]
Monthly balance (f(m) is then calculated as:
[tex]f(m) = Base\ Amount - Monthly\ Spending[/tex]
[tex]f(m) = 90000 - 5\% * m[/tex]
[tex]f(m) = 90000 - 0.05 * m[/tex]
[tex]f(m) = 90000 - 0.05m[/tex]
