Choose True or False for each equation for x = 6.
6x = 12
5 + x = 11
x ÷ 2 = 3
17 – x = 11
Answer:
false true true true
Step-by-step explanation:
The equation for x = 6 is true and would be equal to 6x = 12. and the rest are false.
What does it mean to solve an equation?An equation represents the equality of two or more mathematical expressions. When someone asks you to solve an equation, then they usually mean to find the values of the unknowns for which that equation would be true (the equality between expressions should hold for those values). Solutions to an equation are those values of the variables involved in that equation for which the equation is true.
The given equations are;
6x = 12
Substitute x = 6 to check whether the solution satisfies the equation;
6(6) = 36
Thus, it is False.
5 + x = 11
Substitute x = 6 to check whether the solution satisfies the equation;
5 + x = 11
5+ 6 = 11
Thus, it is True.
x ÷ 2 = 3
Substitute x = 6 to check whether the solution satisfies the equation;
6/2 = 3
Thus, it is True.
17 – x = 11
Substitute x = 6 to check whether the solution satisfies the equation;
17 - 6 = 11
Thus, it is True.
Hence, the equation for x = 6 is true and would be equal to 6x = 12. and the rest are false.

Finally! After nearly two weeks of manual labor in the Georgia summer heat, all of the moving boxes are unpacked and all of your things have a place. You and your three roommates, Alex, Payton, and Jordan, got so lucky in the real estate department. Your apartment is right in the heart of midtown and in walking distance from the Georgia Tech Engineering building where you take the majority of your classes. Everything is perfect! Well… except one crucial component. The four of you cannot seem to agree on an internet and cable provider!
You have narrowed the list of options down to a few of the best companies. All companies offer exactly what the four of you need to continue being top engineering students.The big difference? The price. Your roommates are math enthusiasts and engineering majors just like you, so you know you need to provide extensive evidence to each of them to help move the decision along.
SignoCable has a program where you are able to waive the installation fee and offers your cable for $210 per month.
Urban Cable is offering a special promotion. They are requiring a $320 installation fee upfront. The month to month payment will be $115 for the first 12 months. After the first year, the monthly fee will increase.
ITP Cable requires a lower installation fee than Urban Cable. After six months with this company, you would have paid $1081 since the beginning of the year, and $1257 after 7 months of paying.
MonstroPin Cable company’s installation fee is $100.50. The total payment in August is $59 more than three times the total payment in February.
You’ve decided it’s up to you to save you and your friends money by presenting them with a clear model of the out of pocket expense for all cable companies. Not only do you plan on making a visual representation for Alex, you will even write a proposal that analyses your findings for Payton and Jordan. You will provide them with indisputable evidence of which cable company will provide the most cost effective service.

You wish to purchase a new car, and can afford monthly repayments of up to $150 per month. You see a car you like for $6,000, and are offered financing to secure the purchase. The terms of the deal are that the loan lasts for 5 years, and the annual interest rate is 15.9%. Can you afford to purchase the car on finance?
The monthly repayment of $145.59 is less than expected monthly payment of $150, hence, the individual can afford tp purchase the car on finance
How do we determine affordability in this case?
In order to determine whether the individual can afford to purchase the car on finance, we need to ascertain the monthly payment of the loan based on the terms of deal provided which would be compared to the expected monthly repayment of $150 using a financial calculator as below:
N=60(number of monthly payments in years=5*12)
I/Y=15.9/12(monthly interest rate without the % sign)
PV=-6000(loan principal)

A sequence is shown in the graph.
points at 1 comma 48, 2 comma 12, 3 comma 3, and 4 comma 75 hundredths
Assuming the pattern continues, what is the formula for the nth term?
an = 48(4n)
an = 48(0.25n + 1)
an = 4(48n − 1)
an = 48(0.25n − 1)
Answer:
(d) 48(0.25^(n-1))
Step-by-step explanation:
The points shown on the graph have y-values that decrease by a factor of 4 as x-values increase by 1. The first couple are (1, 48), (2, 12). You want the formula for the n-th term.
Geometric sequenceThe terms of a geometric sequence have a common ratio (r). If the first term is a1, the general term is ...
an = a1(r^(n-1))
ApplicationThe given sequence has first term a1 = 48. The common ratio is ...
r = 12/48 = 1/4 = 0.25
Using these value in the formula for the general term, we find the n-th term to be ...
an = 48(0.25^(n-1)) . . . . n-th term of the pattern

Step-by-step explanation:
The expressions of the range of temperatures would be 2000 - (-120) found in the thermosphere which is the correct answer would be option (D).
What are Arithmetic operations?Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions. The operator that performs the arithmetic operation is called the arithmetic operator.
The fourth layer of the Earth's atmosphere is the thermosphere. It begins just above the mesosphere and rises to a height of 600 kilometres above the Earth's surface.
As you go in height, the temperature in this layer rises. The range of temperatures is from -120°C to 2000°C.
The range of temperatures found in the thermosphere would be the difference between the final temperature and the initial temperature.
initial temperature = -120°C
final temperature = 2000°C
The range of temperatures = final temperature - initial temperature
The range of temperatures = 2000 - (-120)
Therefore, the expressions of the range of temperatures would be 2000 - (-120) found in the thermosphere.

find the point of inflexion for the function f(x)=x^4-6x^2
The points of inflection for the function [f(x) = (x⁴ - 6x²)] are (1, -5) and
(-1, -5).
As per the question statement, we are provided with a function
[f(x) = (x⁴ - 6x²)].
We are required to determine the points of inflection for the above mentioned function.
To solve this question, we will have to calculate the second derivative of the given function. Then, we will have to equate the derivative to zero and solve for x. The obtained values for "x" will be our abscissa, and substituting these values of "x" in f(x), we will obtain our respective ordinates [Since, {y = f(x)}].
[tex]f(x)=(x^{4} -6x^{2})\\or,\frac{d[f(x)}{dx} = \frac{d(x^{4} -6x^{2}) }{dx}\\ or, f'(x)=\frac{dx^{4}}{dx}-\frac{d(6x^{2})}{dx}\\ or, f'(x)=\frac{dx^{4}}{dx}-6\frac{d(x^{2})}{dx}\\or, f'(x)=4x^{(4-1)}-(6*2)[x^{(2-1)}]\\ or,f'(x)=4x^{3}-12x\\[/tex]
Therefore, the second derivative of f(x) = [tex]\frac{d^{2}f(x)}{dx^{2} }[/tex]
[tex]or,f"(x)=\frac{d[f'(x)]}{dx}\\or,f"(x)=\frac{d(4x^{3} -12x)}{dx}\\or, f"(x)=\frac{d(4x^{3}) }{dx}-\frac{d(12x)}{dx}\\ or, f"(x)=4\frac{d(x^{3}) }{dx}-12\frac{d(x)}{dx}\\or,f"(x)=(4*3)[x^{(3-1)}]-(12*1)[x^{(1-1)}]\\ or, f"(x)=12x^{2} -12[/tex]
Now, equating (12x² - 12) to Zero, we get,
[tex](12x^{2} -12)=0\\or,12x^{2} =12\\or,x^{2} =1\\or,x=(1, -1)[/tex]
Now, substituting (x = 1) in f(x), we get,
[tex]y=f(1)=[(1)^{4}-6(1)^{2}]\\ or,y=[1-(6*1)]\\or,y=(1-6)\\or,y=(-5)[/tex]
Hence, one point of inflection for the function [f(x) = (x⁴ - 6x²)] is (1, -5).
Again, substituting [x = (-1)] in f(x), we get,
[tex]y=f(-1)=[(-1)^{4}-6(-1)^{2}]\\ or,y=[1-(6*1)]\\or,y=(1-6)\\or,y=(-5)[/tex]
That is, another point of inflection for the function
[f(x) = (x⁴ - 6x²)] is (-1, -5).
Inflection Point (Of a Function): In differential calculus and differential geometry, an inflection point, point of inflection or flex, is that point on a smooth plane curve at which the curvature changes its concavity i.e. from being "concave up" to being "concave down" or vice versa, or if stated in simpler terms, that point where the curve changes its sign.To learn more about Points of Inflection, click on the link below.

60 - N/D = 1.03643
75 - M/D
75 - (60 - 1.03643D)/D = 1.88079
15 + 1.03643D = 1.88079D
15 = 0.84436D
17.765 = D
D = 17.765
-----------------------------------
60 - M = 1.03643D
60 - 1.03643D = M
M = 60 - 1.03643(17.765)
M = 41.588
