Find the equation of the line that passes through the given point (4, 3) with slope 12
To find the equation of a line given a point and a slope, we can use the point-slope form of the linear equation, which is: y – y1 = m(x – x1) In this formula, (x1, y1) is the point through which the line passes, and m is the slope of the line. For our […]
How many jars of paint can Alton buy with $1800 if each jar costs $114?
To find out how many jars of paint Alton can buy, we need to divide the total amount he has, which is $1800, by the cost of each jar of paint, which is $114. We perform the calculation: Number of jars = Total amount / Cost per jar Number of jars = $1800 / $114 […]
How do you write a rule for the nth term of the arithmetic sequence given a20 = 240 and a15 = 170?
To find the rule for the nth term of the given arithmetic sequence, we start by identifying the information provided: A20 = 240 A15 = 170 In an arithmetic sequence, the nth term can be expressed with the formula: An = A1 + (n – 1) * d where A1 is the first term and […]

How to Convert an Improper Fraction to a Mixed Number
Converting an improper fraction to a mixed number is a straightforward process. An improper fraction is where the numerator (the top number) is greater than or equal to the denominator (the bottom number). Hereโs how you can make the conversion: Divide the numerator by the denominator: This gives you a whole number and a remainder. […]
What are the amplitude, period, phase shift, and midline of fx = 2 sin(x) + 4?
The function fx = 2 sin(x) + 4 is a sinusoidal function. Amplitude: The amplitude is determined by the coefficient in front of the sine function. Here, it is 2. This means that the graph of the sine function oscillates 2 units above and below its midline. Period: The period of a sine function is […]
If A, B, and C are the vertices of a triangle ABC, what is the value of vector AB + BC + CA?
To find the value of the vector sum AB + BC + CA, we can start by expressing each vector in terms of the position vectors of the points A, B, and C. Define the position vectors as follows: Let vector A = ๐A Let vector B = ๐B Let vector C = ๐C Now, […]
Which of the following is an extraneous solution of 45 3x 1 2 x 9 x 12 x 3 x 3 x 12?
To determine if a solution is extraneous, we first need to understand what extraneous solutions are. An extraneous solution is a solution that emerges from the process of solving a problem but does not satisfy the original equation. In the case of the equation provided, you would typically simplify and solve it step by step. […]
What is the formula for surface area of a rectangular prism?
The formula for the surface area of a rectangular prism is given by: Surface Area = 2(lw + lh + wh) Where: l = length of the prism w = width of the prism h = height of the prism To understand this formula, let’s break it down. A rectangular prism has six faces, each […]
For which of the following equations are x = 5 and x = -5 both solutions?
To find the equations for which both x = 5 and x = -5 are solutions, we need to understand that both values need to satisfy the same equation. One way to form such an equation is to use the fact that if x = 5 and x = -5 are roots, the factors of […]
