To find the equation of the line in slope-intercept form (which is y = mx + b, where m is the slope and b is the y-intercept), we first need to determine the slope (m) of the line that passes through the two given points: (3, 1) and (1, 5). The formula to calculate the … Read more
To find the number from which you can subtract half and end up with zero, we can set up a simple equation. Let’s call the unknown number X. According to the problem, when you subtract half of this number from itself, you should get zero. We can express this mathematically as: X – (1/2)X = … Read more
To determine the value of dy/dx when given the expression 3x^2y^2, we need to perform implicit differentiation, assuming there is a relationship between x and y. First, let’s set the expression equal to a constant, say C
To find the slope of the tangent line to the parabola given by the equation y = 8x – x2 at the point (1, 7), we need to perform the following steps: Step 1: Differentiate the Equation The first step is to calculate the derivative of the function with respect to x. The derivative will … Read more
Rewriting the Quadratic in Vertex Form To convert the quadratic function f(x) = x² + 6x + 4 into vertex form, we need to complete the square. The vertex form of a quadratic function is given by: f(x) = a(x – h)² + k where (h, k) is the vertex of the parabola. Steps to … Read more
