What is the middle term of the product of (x - 4)(x - 3)?
Answer:
The middle term of the product of (x - 4)(x - 3) is -7
Step-by-step explanation:
Consider the given expression (x - 4)(x - 3)
We have to find the middle term of the product of (x - 4)(x - 3).
First multiply the given terms, we get,
[tex](x - 4)(x - 3)=x(x-3)-4(x-3)[/tex]
Simplify, we get,
[tex]x(x-3)-4(x-3)=x^2-3x-4x+12[/tex]
Simplify further, we get,
[tex]x^2-3x-4x+12=x^2-7x+12[/tex]
Thus, the middle term of the product of (x - 4)(x - 3) is -7

The midpoint of is m(–8, 1). one endpoint is k(–6, 5). find the coordinates of the other endpoint l.
Jon performs 3 transformations on a pentagon. First, he reflects it over the x-axis. Then, he translates it 3 units to the left and 4 units up. Finally, he reflects the image over the line x = 1. Are the original and transformed images congruent? Justify your answer.
yes; Reflections and translations are rigid motions. Rigid motions preserve the size of the original image.
[Geometry Basics] I'm just checking if this is correct:
~ Endpoint: (-9, -1), midpoint: (8,14)
Answer I got: (25, 31)
~ Endpoint: (10,12), midpoint: (6,9): (2,6)

What is the equation of the circle with a diameter of 6 units and a center located at (2, -5) on the coordinate plane?
The equation of a circle centered at (2, -5) with a diameter of 6 units is (x-2)² + (y+5)² = 9.
Explanation:The equation of a circle in the coordinate plane is given by (x-h)² + (y-k)² = r², where (h, k) are the coordinates of the center of the circle, and r is the radius. In this case, the center of the circle is at (2, -5) and the diameter is 6 units. Therefore, the radius (r) is half the diameter, which is 3 units.
Substituting h=2, k=-5, and r=3 into the equation, we get the equation of the circle: (x-2)² + (y+5)² = 9.

Without graphing, classify the following system as independent, dependent, or inconsistent. y=-3x+4 and 6x+2y=8
a. independent
b. dependent
c. inconsistent
please help
Answer:
Dependent
Step-by-step explanation:
[tex]y=-3x+4[/tex] and [tex]6x+2y=8[/tex]
Lets solve the second equation for y and then substitute it in first equation
[tex]6x+2y=8[/tex]
Subtract 6x on both sides
[tex]2y=-6x+8[/tex]
Divide by 2 on both sides
[tex]y=-3x+4[/tex]
Now we plug it in first equation for y
[tex]-3x+4=-3x+4[/tex]
Add 3x on both sides
[tex]4=4[/tex]
Both sides are same, they are equal. the system has infinite solutions.
They are said to be dependent
Bill buys a red marble and a blue marble. If the total weight of 3 such red marbles and 2 such blue marbles is 84g, and the total weight of 12 such red marbles and 5 such blue marbles is 282g, what is weight of the red marble and the blue marble respectively?
Final answer:
The weight of the red marble is 16 grams, and the weight of the blue marble is 18 grams, based on the solution of the system of linear equations derived from the given total weights of the marbles.
Explanation:
To solve the problem of determining the weight of each marble, we can set up a system of linear equations based on the given information:
Let r be the weight of a red marble in grams.
Let b be the weight of a blue marble in grams.
The total weight of 3 red marbles and 2 blue marbles is 84g.
The total weight of 12 red marbles and 5 blue marbles is 282g.
Based on these statements, we can write two equations:
3r + 2b = 84 (1)
12r + 5b = 282 (2)
We can solve this system of equations by multiplying equation (1) by 4 to eliminate variable b.
(4)(3r + 2b) = (4)(84)
12r + 8b = 336 (3)
Subtract equation (2) from equation (3) to solve for r:
(12r + 8b) - (12r + 5b) = 336 - 282
3b = 54
b = 18 (weight of blue marble)
Substitute value of b in equation (1) to solve for r:
3r + 2(18) = 84
3r + 36 = 84
3r = 48
r = 16 (weight of red marble)
Therefore, the weight of the red marble is 16 grams and the weight of the blue marble is 18 grams.
Find the length of the hypotenuse of a right triangle whose legs are 5 and sqare root of 2
Answer:
The length of the hypotenuse is 3√3 units.
Step-by-step explanation:
It is given that the length of the legs of a right triangle are 5 units and √2 units.
According to the Pythagoras theorem, in a right angled triangle
[tex](hypotenuse)^2=(leg_1)^2+(leg_2)^2[/tex]
Substitute leg₁=5 and leg₂=√2 in the above formula.
[tex](hypotenuse)^2=(5)^2+(\sqrt{2})^2[/tex]
[tex](hypotenuse)^2=25+2[/tex]
[tex](hypotenuse)^2=27[/tex]
Taking square root both the sides.
[tex]hypotenuse=\sqrt{27}[/tex]
[tex]hypotenuse=3\sqrt{3}[/tex]
Therefore the length of the hypotenuse is 3√3 units.

Find the inverse function f^-1(x) for the given function f(x). f(x) =3x-8
Final answer:
To find the inverse of the function f(x) = 3x - 8, you swap x and y and solve for y, resulting in the inverse function f^-1(x) = (x + 8) / 3.
Explanation:
To find the inverse function f-1(x) for the given linear function f(x) = 3x - 8, we will follow these steps:
Replace f(x) with y: y = 3x - 8.
Swap x and y to make it x = 3y - 8.
Solve for y to get the inverse function.
Starting with x = 3y - 8, we add 8 to both sides to obtain x + 8 = 3y. Then, we divide both sides by 3 to isolate y, resulting in y = (x + 8) / 3. Therefore, the inverse function is f-1(x) = (x + 8) / 3.

What is logarithm? What is a mathematical equation and expression?A quantity representing the power to which a fixed number (the base) must be raised to produce a given number. We can write -[tex]$\log_{b}({b^x})=x[/tex]
A mathematical expression is made up of terms (constants and variables) separated by mathematical operators. A mathematical equation is used to equate two expressions. A mathematical equation is used to equate two expressions. Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.We have 31,100 is rounded to the nearest power of 10 and [N] represents a power of 10.
We can write -
10ⁿ = 31100
10ⁿ = 311 x 10²
10ⁿ ⁻ ² = 311
log(10ⁿ ⁻ ²) = log(311)
(n - 2) log 10 = log (311)
n - 2 = log(311)/log(10)
n - 2 = 2.5
n = 4.5
n = 5 (approx.)
Therefore, we get the approximate value of [n] as 5.

When rounding 31,100 to the nearest power of 10, we get the value of n is 4.
To find the value of n when 31,100 is rounded to the nearest power of 10, we first need to determine which powers of 10 are closest to 31,100. The nearest powers of 10 to 31,100 are 104 (10,000) and 105 (100,000). Since 31,100 is closer to 104 than to 105, we round it down to 104.
Therefore, when 31,100 is rounded to the nearest power of 10, the value of n is 4.
The process involves converting the number into scientific notation and then adjusting the exponent, which represents the number of places the decimal point moves. In our case, to convert 31,100 to a number between 1 and 10, we would express it as 3.11 × 104, confirming that the value of n is 4.

(5x^2+38x+18) divided (x+7) what is the quotient and the remainder
To determine the quotient and remainder for (5x^2+38x+18) divided by (x+7), polynomial long division must be used, involving dividing terms, multiplying and subtracting until the remainder is obtained.
Explanation:To find the quotient and remainder of the division of polynomials (5x2+38x+18) by (x+7), we can use polynomial long division.
Divide the first term of the dividend, 5x2, by the first term of the divisor, x, to get the first term of the quotient, which is 5x. Multiply the entire divisor (x+7) by 5x and subtract from the dividend. Bring down the next term from the dividend and repeat the process until there are no more terms to bring down. The last line after the subtraction will be the remainder.
By doing this, you will obtain the quotient and the specific remainder for this division.
