Answer:
6=8x
Step-by-step explanation:
Answer:
6+8x
Step-by-step explanation
We are going to make sure we can do this as best as possible. We need to make sure that the words that you are reading are making sense.
Sum can be taken out because its just 6. We do not know what adds to 6, it could be 1 +5, 2+4, 3+3, -3 and 9, WE DO NOT KNOW. So don't put extra information into the expression, when it is not given.
The and would be an addition to something, because when we are speaking and say the word AND, we want to add to that sentence. So, and is the plus sign.
6+
Then product is multiplication. So 8 times x.
Put it all together and you get the expression:
6+8x

What is the mean of 6,3,2,1,9,9
Answer:
[tex]\boxed{ \bold{ \huge{ \boxed{ \sf{5}}}}}[/tex]
Step-by-step explanation:
Given data : 6 , 3 , 2 , 1 , 9 , 9
Σfx = 6 + 3 + 2 + 1 + 9 + 9 = 30
N ( total number of observation ) = 6
Finding the mean

Answer:
x = 1?
Step-by-step explanation:
I think functions are basically just variables but extra so they both act the same. I'm not 100% sure but I Think
if f(x) = -5x + 1 when f(x) = 6,
replace f(x) with 6 so,
6 = 5x + 1
1 - 6 = 5x + 1 - 1
(subtract one on both sides to isolate the variable)
5 = 5x
5/5 = 5x/5
(to Actually isolate the variable lol
1 = x or x = 1
I believe is the answer? please comment if I'm wrong

A student multiplies (4+5i) (3-2i) incorrectly and obtains 12-10i. What is the student's mistake? Select the two correct answers. A. They multiplied the second number by the real part of the first number. B. In the multiplication of the imaginary parts, the student forgot to square the i. C. The student has only multiplied the real parts and the imaginary parts. D. The student has added the real parts and multiplied the imaginary parts. E. The student has multiplied the second number by the imaginary part of the first number.
Answer:
B. In the multiplication of the imaginary parts, the student forgot to square the i. C. The student has only multiplied the real parts and the imaginary parts.Step-by-step explanation:
Before we figure out the student mistake, let us find the product of the complex numbers ourselves first.
(4+5i) (3-2i)
open the parenthesis
= 4(3)-4(2i)+3(5i)+5i(-2i)
= 12-8i+15i-10i²
Note that in complex number, i² = -1, hence the expression will become;
= 12-8i+15i-10(-1)
= 12-8i+15i+10
collect like terms by separating the real from imaginary part
= 12+10-8i+15i
= 22+7i
From the students answer i.e 12-10i, it can be concluded that;
In the multiplication of the imaginary parts, the student forgot to square the i and the student has only multiplied the real parts and the imaginary parts 4 and 3 to get 12
A single-payment loan of $5,955. Interest rate of 8.75 percent. Days of ordinary
interest: 42. Round to the nearest hundredth. What is the interest owed? What is the maturity value?
Answer:
interest owned = PTR/100
= 5955*(42/365)*8.75/100 =59.96
maturity value = 5955+59.96=6054.96

6y - 5z = -8
3z = -6
4x - 3y - 2z= 21
Answer:
x = 2 y = - 3z = - 2Step-by-step explanation:
6y - 5z = -8 .......... Equation 1
3z = -6 ................... Equation 2
4x - 3y - 2z= 21...... Equation 3
First solve for z in Equation 2
That's
3z = - 6
Divide both sides by 3
z = - 2Next substitute the value of z into Equation 1 in order to find y
We have
6y - 5(-2) = - 8
6y + 10 = - 8
6y = - 8 - 10
6y = - 18
Divide both sides by 6
y = - 3Finally substitute the values of y and z into Equation 3 to find the value of x
That's
4x - 3(-3) - 2(-2) = 21
4x + 9 + 4 = 21
4x + 13 = 21
4x = 21 - 13
4x = 8
Divide both sides by 4
x = 2So the solutions are
x = 2 y = - 3z = - 2Hope this helps you
Can you simplify this algebraic expression? Type your answer below!
(2x-4) - (6x +6)
Answer:
-4x -10
Step-by-step explanation:
remove paranthese: 2x−4−6x−6
collect like terms: (2x−6x)+(−4−6)
−4x−10
The simplified Algebraic Expression of (2x-4) - (6x +6) is -4x - 10.
What is Expression?A mathematical operation such as subtraction, addition, multiplication, or division is used to combine terms into an expression. In a mathematical expression, the following terms are used:
An absolute numerical number is referred to as a constant.Variable: A symbol without a set value is referred to as a variable.Term: A term can be made up of a single constant, a single variable, or a mix of variables and constants multiplied or divided.Coefficient: In an expression, a coefficient is a number that is multiplied by a variable.Given:
(2x-4) - (6x +6)
Now, solving the above expression
= (2x-4) - (6x +6)
= 2x - 4 - 6x - 6
Combining the like terms
= (2x- 6x) + (-4-6)
= -4x - 10
Hence, the simplified expression is -4x-10.

Determine whether the study is an observational study of an experiment. Explain.
In a survey of 1117 adults in a country, 54% said the country's leader should release all medical information that might affect their ability to serve The study is_____because it____a treatment to the adults.
Answer: Observational ; does not
Step-by-step explanation: The main distinguishing factor between an experimental study and an observational study lies in the administration of treatment to the participant of the study. In experimental study, some or all the participant in the study are subjected or exposed to a certain treatment and their response to such treatment. ON THE OTHER HAND, Observational study is usually employed when there is a need to gather information on a particular subject matter without directly influencing the participants. In the scenario above, participants were not given any TREATMENT as they were only required to gather information and not to measure the effect of a treatment.

Which of the following scenarios exhibits a function relation? Take the first set listed to be the domain of the relation.
Answer:
-the set of people with Social Security cards and the set of Social Security numbers
Explanation:
There's literally no relation between the height of a tree and the number of trees in a forest that can be clearly seen. Same goes to models and people in a certain town. Birthdays and Students in Class definitely have no correlation as isolated pieces of information. The number of people with social security numbers and the amount of numbers in a SS Card, though, have a direct relation, since the number has to be large so the amount of people that need such a number can have unique numeric representations of their Social Security.

A hot air balloon ascended to a height of 25 meters 2 minutes after launch. After some time, the balloon's altitude began to change by -2⅕ meters every minute for 7 minutes. To avoid a tree, the balloon flew up by 8½ meters. What is the new altitude of the balloon? expression for problem?
Answer:
18.1 m
Step-by-step explanation:
For this problem, we will simply use the initial height of 0 meters, the height of 25 meters after 2 minutes, the decline of 2.2 meters every minute for 7 minutes, and a final increase of 8.5 meters to find the final altitude of the ballon.
0m + 25m - 2.2m(7) + 8.5m = ?
25m - 15.4m + 8.5m = ?
9.6m + 8.5m = ?
18.1m = ?
Hence, the final altitude of the ballon is 18.1m.

Suppose the material is being heated.
a. What change of state is represented by line segment A?
The solid changes to liquid state. The change of state is Melting.
b. What is happening to the average kinetic energy of the particles during the change of state represented by line segment B? The average kinetic energy of the particle increases as the heat is applied but remains constant during the change of state.
c. What physical property does the temperature at point B represent?
Vapourisation.
If the liquid is kept at this temperature what state of matter will be observed?
If the temperature persists, the state of matter that will be observed will be gas. Because the liquid must have turned out to vapour.

foot long. Liz's feet are only
2
3
foot long.
What expression can be used to find out how much longer Liz's boot prints are than her feet?
Answer:
See Explanation
Step-by-step explanation:
The question has missing details; However, the following explanation will guide.
Represent the boots print with y and the Liz's feet with x
To calculate how much the boot is longer than her feet, we simply get the difference between the length of the boot's print and her feet;
i.e.
[tex]Difference = y - x[/tex]
Note that her boot print (y) will always be greater than her feet (x)
Take for instance;
[tex]y = 3\ ft[/tex]
[tex]x = 2\ ft[/tex]
The difference will be
[tex]Difference = 3ft - 2ft[/tex]
[tex]Difference = 1ft[/tex]
