Answer:
The solution of [tex]x^3-2x^2+16x-32=0[/tex] is [tex]\mathbf{x=2,x=4i,x=-4i}[/tex]
So, the real solutions is: x = 2
Imaginary solutions are : x = 4i, x = -4i
Step-by-step explanation:
We need to find real and imaginary solutions to the equations [tex]x^3-2x^2+16x-32=0[/tex]
First of all we will make groups
[tex](x^3-2x^2)(+16x-32)=0[/tex]
Finding common terms from the groups
[tex]x^2(x-2)+16(x-2)=0\\(x-2)(x^2+16)=0[/tex]
Now we know that if ab=0 then a=0 , b=0
[tex]x-2=0, x^2+16=0\\Simplifying:\\x=2, x^2=-16\\Taking\: square\: root\\x=2,\sqrt{x^2}=\sqrt{-16}\\x=2, x=\pm\sqrt{-16}\\x=2,x=\m\sqrt{-1}\sqrt{16} \\We\:know\:\sqrt{-1}=i \:and \sqrt{x} \:\sqrt{16}=4 \\x=2,x=\pm4i\\x=2,x=4i,x=-4i[/tex]
The solution of [tex]x^3-2x^2+16x-32=0[/tex] is [tex]\mathbf{x=2,x=4i,x=-4i}[/tex]
So, the real solutions is: x = 2
Imaginary solutions are : x = 4i, x = -4i

Helppp find the solution to this equation 2x+4y=8. x=3y-6 What do x and y  equal
Answer:
y = 2, x = 0
Step-by-step explanation:
2x + 4y = 8
x = 3y - 6
2x + 4y = 8
2 ( 3y - 6 ) + 4y = 8
10y - 12 = 8
10y = 20
y = 2
x = 3y - 6
x = 3 ( 2 ) - 6
x = 0
Mike has a credit rating of 720. Tyler has a credit rating of 560. Mike and Tyler apply for identical loans from Park Bank. Mike is approved for a loan at 3.2% interest, and Tyler is approved for a loan that charged 3 percentage points higher because of his inferior credit rating. What interest rate is Tyler charged?
Answer:
6.2%
Step-by-step explanation:
Credit rating is an evaluation of the credit risk of a borrower, that how often a person is going to repay their debt, by credit rating it predicts the ability of the debtor to payback.
Mike has credit rating = 720
Tyler has credit rating = 560
Both are approved for loan. Mike's Credit score is higher, which means he is a much safer debtor as compared to Tyler. Mike will be able to pay back much easily than Tyler. Therefore Mike interest rate is 3.2%
Interest rate of Tyler is higher as he is not that trusted and has low Credit rating. Tyler is approved for a loan that charged 3 percentage points higher because of his inferior credit rating so it interest on the loan will be
Interest = 3.2%+3% = 6.2%

Answer:
8 baskets worth 3 points each and 4 baskets worth 2 points each
Step-by-step explanation:
It is 8 baskets worth 3 points each and 4 baskets worth 2 points each because it says Juarez scored twice as many baskets worth 3 points than the baskets worth 2 points. 4 x 2 = 8
-----------------------------------------------------------------------------
6 baskets worth 3 points each and 7 baskets worth 2 points each : wrong because 7 x 2 = 14.
10 baskets worth 3 points each and 1 basket worth 2 points : wrong because 1 x 2 = 2.
4 baskets worth 3 points each and 10 baskets worth 2 points each: wrong because 10 x 2 = 40.

swimming pool is being filled with a hose. The hose fills the pool at a constant rate. The pool's water level rises 4 inches in hours. What rate per hour of the water level change?
The required rate of the level of change of water in the swimming pool is 1 / 3 level per hour.
Given that,
The swimming pool is being filled with a hose.
The pool's water level rises 4 inches in hours.
To determine the rate per hour of the water level change.
Here,
Let 1 level of pool = 1 feet = 12 inches
The pool's water level rises 4 inches in hours. So, ti will rises 12 inches in 3 hours, which implies level change after 3 hours
Now the rate of level change of water = 1 / 3 level per hour
Thus, the required rate of the level of change of water in the swimming pool is 1 / 3 level per hour.

Identify the best method for solving the given
system of equations. DO NOT SOLVE. Justify your
choice using academic vocabulary.
3x + 2y = 0
x - 5y = 17
2x + y - z = 15
4x - 3y + 7z = -11
X + y + z = 2
solve the system of equations
Answer:
The given system of equations is :
2x + 3y + 5z = 1 -> eq. (1)
3x + 2y + z = 5 -> eq. (2)
Multiplying eq. (1) with 3 and eq. (2) with 2, we get :
6x + 9y + 15z = 3 -> eq. (3)
and, 6x + 4y + 2z = 10 -> eq. (4)
respectively.
Subtracting eq. (4) from eq. (3) :
5y + 13z = -7 -> eq. (5)
Multiplying eq. (1) with 2 and eq. (2) with 3, we get :
4x + 6y + 10z = 2 -> eq. (6)
and, 9x + 6y + 3z = 15 -> eq. (7)
respectively.
Subtracting eq. (7) from eq. (6) :
-5x + 7z = -13 -> eq. (8)
Let z = t, where t is a parameter.
We can write eq. (5) and eq. (8) as :
5y + 13t = -7 & -5x + 7t = -13
i.e., 5y = -7 - 13t & 5x = 13 + 7t
y = -(7/5) - (13t/5) & x = (13/5) + (7t/5)
Therefore, the solution for the given system of equations is :
x = (13/5) + (7t/5)
y = -(7/5) - (13t/5)
z = t
where, t can take any value.

two variables that move in opposite directions are: a. said to have a positive correlation. b. called independent variables. c. said to have zero correlation. d. said to be inversely related.
Two variables that move in opposite directions are said to be inversely related.
A negative correlation is a relationship between two variables that move in opposite directions. In other words, when variable A increases, variable B decreases. A negative correlation is also known as an inverse correlation.
The concept of negative correlation is important for investors or analysts who are considering adding new investments to their portfolio. When market uncertainty is high, a common consideration is re-balancing portfolios by replacing some securities that have a positive correlation with those that have a negative correlation.
Here are some common examples of a negatively correlated relationship between assets:
1. Oil prices and airline stocks
2. Gold prices and stock markets (most of the time, but not always)
3. Any type of insurance payoff

correct answer?
Answer and Step-by-step explanation:
We are not given the function in question, but in order to explain, will form a function. Suppose f(x) = 3x + 2.
If f(x) = 17, then
3x + 2 = 17, to find the value of x, we have solve for x in the equation.
3x = 17 – 2
3x = 15
x = 5
This is the method that can be used to solve problems of this nature.

Caroline’s Coffee Shop sells a refill mug for $8.95. Each refill costs $1.50. Last month Sean spent $26.95 on a mug and refills. How many refills did he buy?
Answer:
Alright! First you'd have to subtract the flat fee of the mug which is $8.95, then you'd have to divide by the rate which is $1.50. Your equation would be:
(26.95 - 8.95) ÷ 1.50 = r
Then you solve using your head.. lol.
(26.95 - 8.95) = 18.
(18 ÷ 1.50) = 12.
R = 12.
