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.

The number of wins for a high school football team is measured for the season. When the team plays at home, it is generally believed that they will win. Comparing the location of the game and the number of wins, a correlation coefficient of 0. 891 is calculated. What would this imply about the football team winning at home? The scatter plot would closely resemble a straight line with a positive slope. The data has a strong, positive correlation, but causation cannot be determined. The scatter plot would closely resemble a straight line with a positive slope. The data has a strong, positive correlation, and a causal relationship exists between the team playing at home and winning. The scatter plot would not be represented by a line of best fit with a positive slope. There is a weak correlation between the football team playing at home and winning. There is no causation and almost no correlation between the football team playing at home and winning.

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:
a=-2b=4c=-3Finally, the correct answer is the last option: a = –2, b = 4, c = – 3

The square of a number is added to 6
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.

Order the steps to solve the equation log3(x 2) = log3(2x2 − 1) from 1 to 6. 0 = (2x − 3)(x 1) 0 = 2x2 − x −3 Potential solutions are −1 and 3 2. 2x − 3 = 0 or x 1 = 0 x 2 = 2x2 − 1 3log3(x 2) = 3log3(2x2 − 1).
The exponent of the log rule says that the raising a logarithm with a number to its base is equal to the number.
Ordered steps to solve the equation are,
1) [tex]3^{\log_3(x^2) }=3^{\log_3(2x^2 - 1)}[/tex]2) [tex]0=2x^2-x-3[/tex]3) [tex]0=2x^2-x-3[/tex]4) [tex](2x-3)(x+1)=0[/tex]5) [tex]2x-3=0,\;\;\;\;x+1=0[/tex]6) The potential solution are -1 and 3/2.What is exponent of log rule?The exponent of the log rule says that the raising a logarithm with a number to its base is equal to the number.
For example,
Let k is the number and a is the base thus,
[tex]a^{log_a(k)}=k[/tex]
Given information-
The equation given in the problem is,
[tex]\log_3(x^2) =\log_3(2x^2 - 1)[/tex]
Order of steps to solve the equation are-
1) Take the base 3 both the sides as,[tex]3^{\log_3(x^2) }=3^{\log_3(2x^2 - 1)}[/tex]
2)The exponent of the log rule says that the raising a logarithm with a number to its base is equal to the number. Thus,[tex]x^2+2=2x^2-1\\[/tex]
3) Take the variable with same power one side and solve them by equating to zero, we get,[tex]0=2x^2-x-3[/tex]

A triangle has sides with lengths of 5 meters, 12 meters, and 13 meters. Is it a right triangle?
Answer:
yes :
use the following formula :
a^2 +b^2 = c^2
now apply it to the problem :
5^2+12^2=13^2
do the exponent :
25 + 144 =169
now add
169 =169
if they are equal , then it is a right triangle .
