To solve the equation y = 2mx + 9b for x, subtract 9b from both sides, and then divide by 2m. The result is x = (y - 9b) / (2m). This manipulation is emblematic of solving linear equations which are foundational in algebra.
The student is asking to solve the linear equation y = 2mx + 9b for the variable x. This type of problem involves algebraic manipulation to isolate the variable of interest. Here are the steps to solve for x:
Subtract 9b from both sides of the equation: y - 9b = 2mx.Divide both sides by 2m to solve for x: x = (y - 9b) / (2m).In this case, y is the dependent variable, m is the slope of the line, and b would be the y-intercept if this equation were graphed on a coordinate plane. To better understand this concept, let's take the specific equation y = 9 + 3x as an example which is a linear equation with b set to 9 and m set to 3.
To visualize this equation, one can construct a table of values by selecting various x values and calculating the corresponding y values. Then, these points are plotted on a graph to show the linear relationship. This process is depicted in Table A1 and Figure A1, with the equation illustrated in a graph.
The general form of a linear equation is y = mx + b, where m represents the slope and b the y-intercept. In these exercises, understanding and manipulating this form helps us find relationships between variables and understand how changes in one variable affect another.

Option C correctly applies the Law of Syllogism. By combining the hypothesis from the first statement, 'If it is springtime, you will plant flowers in the garden' with the conclusion of the second, 'If you plant flowers in the garden, your yard will smell good' we form 'If it is springtime, then your yard will smell good'.
Explanation:The question deals with logical reasoning, specifically the laws of syllogism and detachment. The Law of Syllogism takes two conditional statements and forms a conclusion by combining the hypothesis of one statement with the conclusion of another. The Law of Detachment, also known as Modus Ponens, applies when a single conditional statement and the affirmation of its hypothesis lead to the affirmation of its conclusion.
Looking at the options:
A. The statement does not apply the law of syllogism.
B. The statement does not apply the law of detachment.
C. This statement correctly applies the Law of Syllogism. We have two statements: 'If it is springtime, you will plant flowers in the garden' and 'If you plant flowers in the garden, your yard will smell good'. Combining the hypothesis of the first with the conclusion of the second gives us 'If it is springtime, then your yard will smell good'.
D. This accurately applies the law, but the law it uses is not mentioned.

Jenny ball bounced 8 times farther than clarks ball. The two balls bounced a total distance of 36 inches. How far did Jenny's ball bounce?
The correct answer is that Jenny's ball bounced 32 inches.
To solve the problem, let's denote the distance that Clark's ball bounced as [tex]\( d \)[/tex] inches. According to the problem, Jenny's ball bounced 8 times farther than Clark's ball, so the distance Jenny's ball bounced is [tex]\( 8d \)[/tex] inches.
The total distance bounced by both balls is the sum of the distances each ball bounced, which is given as 36 inches. Therefore, we can set up the following equation:
[tex]\[ d + 8d = 36 \][/tex]
Combining like terms, we get:
[tex]\[ 9d = 36 \][/tex]
To find the value of [tex]\( d \)[/tex], we divide both sides of the equation by 9:
[tex]\[ d = \frac{36}{9} \][/tex]
[tex]\[ d = 4 \][/tex]
Now that we have the distance Clark's ball bounced, which is 4 inches, we can find the distance Jenny's ball bounced by multiplying [tex]\( d \)[/tex] by 8:
[tex]\[ 8d = 8 \times 4 \][/tex]
[tex]\[ 8d = 32 \][/tex]
So, Jenny's ball bounced 32 inches.

Sketch the region bounded by the curves y=9x3,y=9 and x=0 then find the volume of the solid generated by revolving this region about the x-axis.
The volume of the solid generated is 218.01 cubic units
The curves are given as:
[tex]y = 9x^3[/tex], y = 9
[tex]x = 0[/tex]
Start by calculating x at [tex]y = 9x^3[/tex]
Substitute 9 for y
[tex]9x^3 = 9[/tex]
Divide both sides by 9
[tex]x^3 = 1[/tex]
Take the cube roots of both sides
[tex]x = 1[/tex]
So, the equation of the volume is then represented as:
[tex]V = \pi \int\limits^a_b {9^2 - (9x^3)^2} \, dx[/tex]
[tex]V = \pi\int\limits^a_b {81 - 81x^6} \, dx[/tex]
Where [a,b] = [1,0]
So, we have:
[tex]V = \pi\int\limits^1_0 {81 - 81x^6} \, dx[/tex]
Factor out 81
[tex]V = 81\pi\int\limits^1_0 {1 - x^6} \, dx[/tex]
Integrate
[tex]V = 81\pi [x - \frac 17x^7]|\limits^1_0[/tex]
Expand
[tex]V = 81\pi ([1 - \frac 17(1)^7] - [0 - \frac 17(0)^7] )[/tex]
[tex]V = 81\pi ([1 - \frac 17] )[/tex]
[tex]V = 81\pi * \frac 67[/tex]
So, we have:
[tex]V = 81 * 3.14 * \frac 67[/tex]
[tex]V = 218.01[/tex]
Hence, the volume of the solid generated is 218.01 cubic units

Identify any vertical asymptotes and horizontal asymptotes? (Enter your answers as comma-separated lists of equations. If an answer does not exist, enter DNE.) f(x) = −3(x + 3)(x − 2) / (x − 4)(x − 2)
The vertical asymptotes are x = 4 and x = 2, and the horizontal asymptote is y = -3.
Explanation:The given function is f(x) = −3(x + 3)(x − 2) / (x − 4)(x − 2).
To find the vertical asymptotes, we need to determine the values of x for which the function approaches positive or negative infinity. The denominator of the rational expression cannot be equal to zero, so we set it equal to zero and solve for x: (x − 4)(x − 2) = 0. This gives us two vertical asymptotes at x = 4 and x = 2.
To find the horizontal asymptote, we need to examine the highest power of x in the numerator and denominator. In this case, both the numerator and denominator have the same highest power, which is x^1 or simply x. Therefore, to find the horizontal asymptote, we compare the coefficients of the highest power of x. The coefficient of x in both the numerator and denominator is -3. So the horizontal asymptote is y = -3.

What is a rational function?In Mathematics and Geometry, a rational function refers to a type of function which is expressed as a fraction.
By critically observing the rational function [tex]f(x)=\frac{-3(x + 3)(x - 2)}{(x -4)(x - 2)}[/tex] shown above, we can logically deduce that its vertical asymptote can be determined by solving the denominator as follows;
(x - 2)(x - 4) = 0
x = 2 and x = 4.
Since the degree of the numerator is the same as the degree of the denominator, we can reasonably infer and logically deduce that this rational function's horizontal asymptote can be calculated by dividing the leading coefficient of the numerator by the leading coefficient of the denominator as follows;
y = -3/1
y = -3.

What is the distance around a triangle that has sides measuring 2 1/8 ft 3 1/2 ft and 2 and 1/2 ft
Suppose that you have 8 cards. 5 are green and 3 are yellow. the 5 green cards are numbered 1, 2, 3, 4, and 5. the 3 yellow cards are numbered 1, 2, and 3. the cards are well shuffled. suppose that you randomly draw two cards, one at a time, and with replacement. ⢠g1 = first card is green ⢠g2 = second card is green enter the probability as a fraction. p(g1 and g2)
The probability of drawing a green card on both the first and second draw, with replacement, is 25/64, as each draw is an independent event with the same probability of 5/8 for drawing a green card.
Explanation:The problem is asking us to compute the probability of drawing two green cards in succession, with replacement, from a deck that contains eight cards of which five are green and three are yellow. Since the draws are independent and with replacement, the probability of an event occurring on the first draw is not affected by the second draw, and vice versa.
To calculate the probability of drawing a green card on the first draw, denoted as P(G₁), we look at the number of green cards and the total number of cards. There are 5 green cards out of 8 total cards, so P(G₁) = 5/8.
Because we are replacing the drawn card before the second draw, the probability of drawing a green card on the second draw, denoted as P(G₂), remains the same as for the first draw, thus P(G₂) = 5/8.
The probability of both events happening, denoted as P(G₁ and G₂), is the product of the individual probabilities since the draws are independent. Therefore, we have:
P(G₁ and G₂) = P(G₁) * P(G₂) = (5/8) * (5/8) = 25/64.

a wire 30 cm long is cut into two pieces. the longer piece is 6 cm longer than the shorter piece. find the length of the shorter piece of wire
The length of the shorter piece of wire is 12 cm, which is found by setting up the equation x + (x + 6) = 30, where x is the length of the shorter piece.
The student has asked to find the length of the shorter piece of wire when a 30 cm long wire is cut into two pieces, with the longer piece being 6 cm longer than the shorter piece. To solve this, we need to set up a simple equation based on the information given.
Let's represent the length of the shorter piece as x cm. Since the longer piece is 6 cm longer than the shorter piece, we can represent the longer piece as (x + 6) cm
We are told that the total length of the wire before it was cut was 30 cm. Therefore, the sum of the lengths of both pieces must equal 30 cm. This gives us the equation:
x + (x + 6) = 30
Simplifying the equation, we get:
2x + 6 = 30
Subtracting 6 from both sides of the equation gives us:
2x = 24
Dividing both sides by 2 to solve for x gives us:
x = 12
