The simplification of the expression 4 + 3x/7 -2 - 2x/7 is 2 + x/7.
The correct answer is B.
What is an expression?One mathematical expression makes up a term. It might be a single variable (a letter), a single number (positive or negative), or a number of variables multiplied but never added or subtracted. Variables in certain words have a number in front of them. A coefficient is the number used before a phrase.
Given:
We have the expression,
4 + 3x/7 -2 - 2x/7
Simplifying,
4 + 3x/7 -2 - 2x/7
= 3x/7 - 2x/7 + 4 -2
= (3x-2x)/7 + 2
= x/7 + 2
Therefore, 2 + x/7 is the value of the expression.

Find the ratio of 3 km to 3000 m
Answer:
1 : 1
Step-by-step explanation:
Step 1) Convert kilometers to meters.
1 kilometers = 1,000 meters
3 kilometers = 3,000 meters
Step 2) Create the ratio.
The ratio is now 3,000 meters to 3,000 meters, which can be written as 3,000 m : 3,000 m.
Step 3) Simplify the ratio.
By dividing by 3,000 on both sides, 3,000 m : 3,000 m simplifies to 1 meter : 1 meter.
Skylar is going to invest $69,000 and leave it in an account for 6 years. Assuming the
interest is compounded continuously, what interest rate, to the nearest hundredth of
a percent, would be required in order for Skylar to end up with $105,000?
[tex]~~~~~~ \textit{Continuously Compounding Interest Earned Amount} \\\\ A=Pe^{rt}\qquad \begin{cases} A=\textit{accumulated amount}\dotfill & \$105000\\ P=\textit{original amount deposited}\dotfill & \$69000\\ r=rate\to r\%\to \frac{r}{100}\\ t=years\dotfill &6 \end{cases}[/tex]
[tex]105000=69000e^{\frac{r}{100}\cdot 6}\implies \cfrac{105000}{69000}=e^{\frac{3r}{50}}\implies \cfrac{7}{46}=e^{\frac{3r}{50}} \\\\\\ \log_e\left( \cfrac{35}{23} \right)=\log_e\left( e^{\frac{3r}{50}} \right)\implies \ln\left( \cfrac{35}{23} \right)=\cfrac{3r}{50}\implies 50\cdot \ln\left( \cfrac{35}{23} \right)=3r \\\\\\ \cfrac{50\cdot \ln\left( \frac{35}{23} \right)}{3}=r\implies 6.9976\approx r\implies \stackrel{\%}{7.00}\approx r[/tex]

Polynomials are expressions that uses variables and numbers to represent its terms
The missing exponent of the y in the second term is 3
How to determine the missing exponentThe polynomial is given as:
[tex]6xy^2-5x^2y^?+9x^2[/tex]
From the question, we understand that the degree of the polynomial is 3
In the equation, the highest exponent of x or y is 2.
This means that, the missing exponent has to be 3.
So, the polynomial becomes
[tex]6xy^2-5x^2y^3+9x^2[/tex]
Hence, the missing exponent of the y in the second term is 3

What are the values of a, b, and c in the quadratic equation –2x2 + 4x – 3 = 0?
a = 2, b = 4, c = 3
a = 2, b = 4, c = –3
a = –2, b = 4, c = 3
a = –2, b = 4, c = – 3
By definition, the correct answer is the last option: a = –2, b = 4, c = – 3
Definition of cuadratic functionA quadratic function is a polynomial function with one or more variables in which the highest degree term is of the second degree.
That is, a quadratic function is a type of function that is characterized by being a second degree polynomial, that is, it has a maximum degree of two, which is why it is also called a second degree function.
The general form of a quadratic function is:
f(x)= ax² +bx +c
where a, b, and c are real numbers and a is nonzero.
The graph of a quadratic function is a curve called a parabola. Parabolas open up or down.
Quadratic equation –2x² + 4x – 3 = 0Comparing with the general form of a quadratic function, you can observe that:

For the function f(x)=(x+6)^3 find f^-1(x)
PLEASE HELP THANK YOU!
======================================================
Explanation:
Replace f(x) with y.
Swap x and y, then solve for y to get the inverse.
[tex]f(x) = (x+6)^3\\\\y = (x+6)^3\\\\x = (y+6)^3\\\\\sqrt[3]{x} = y+6\\\\y = -6+\sqrt[3]{x}\\\\f^{-1}(x) = -6+\sqrt[3]{x}\\\\[/tex]
To solve for y, I first applied the cube root to both sides. Then I subtracted 6 from both sides.
