To solve the equation 3/4x + 3 - 2x = -1/4 + 1/2x + 5, we first need to simplify both sides by combining like terms:

3/4x - 2x + 3 = -1/4 + 1/2x + 5

Next, we can simplify the fractions on the right side by finding a common denominator of 4:

3/4x - 2x + 3 = -1/4 + 2/4x + 20/4

Simplifying the right side further, we get:

3/4x - 2x + 3 = 19/4 + 1/2x

Now we can isolate the variable x by moving all the terms containing x to one side of the equation and all the constants to the other side:

3/4x - 2x - 1/2x = 19/4 - 3

Combining like terms:

-5/4x = 5/4

Finally, we can solve for x by multiplying both sides by the reciprocal of -5/4:

x = -1

Therefore, the solution to the equation is x = -1.

The correct numerical expression for "12 times the sum of 5 and 25 minus 2" by simplification is option (b) , i.e 12 x (5 + 25) − 2.

The height of a lean-to roof that has a slanted height of 325 cm and an angle of elevation of 22 degrees is 131.30 cm.

The tangent function in trigonometry describes the relationship between an angle's adjacent and opposing sides. The angle of elevation is the angle formed by a horizontal line and a line leading from the observer's eye to a higher-than-horizontal object. When calculating an object's height with the tangent function, we utilize the angle of elevation and the length of the neighbouring side (in this example, the slanted height) to get the length of the opposing side (the height). As a result, the height of the object increases with increasing tangent value and elevation angle.

Given that, a roof has slanted height of 325 cm and an angle of elevation of 22 degrees.

Using the trigonometric functions:

tan(22) = h / 325

h = 325 * tan(22)

h ≈ 131.30 cm

Hence, the height of a lean-to roof that has a slanted height of 325 cm and an angle of elevation of 22 degrees is 131.30 cm.

The base of the exponential function (1.75) is greater than 1, this represents exponential growth. As x increases, the value of the function will grow at an increasing rate.

Exponential growth is a mathematical concept that describes a process where a quantity grows at an increasing rate proportional to its current value. In other words, the larger the quantity, the faster it grows. This leads to a graph that is characterized by a rapid upward curve that becomes steeper and steeper over time.

Exponential growth is often represented by the equation y = abˣ, where y is the final amount, a is the initial amount, b is the growth factor or base, and x is the time or number of periods.

The function f(x) = a(1+r)ˣ represents exponential growth, where "a" is the initial value, "r" is the growth rate as a decimal, and "x" is the time variable.

In this case, the initial value is 50, and the growth rate is 75%, or 0.75 as a decimal. Therefore, the equation for the function becomes:

f(x) = 50(1+0.75)ˣ

Simplifying this expression, we have:

f(x) = 50(1.75)ˣ

Since the base of the exponential function (1.75) is greater than 1, this represents exponential growth. As x increases, the value of the function will grow at an increasing rate.

We can infer that the function y = 3 log2x - 5 has the following end behaviour:

A relation between a collection of inputs and outputs is known as a function. A function is, to put it simply, a relationship between inputs in which each input is connected to precisely one output. Each function has a range, codomain, and domain. The usual way to refer to a function is as f(x), where x is the input. A function is typically represented as y = f. (x).

In mathematics, a function is a unique arrangement of the inputs (also referred to as the domain) and their outputs (sometimes referred to as the codomain), where each input has exactly one output and the output can be linked to its input.

from the question:

We may look at what happens to the function as x gets closer to positive and negative infinity to figure out the final behavior of the function y = 3 log2x - 5.

The formula 3 log2x also approaches infinity as x moves closer to positive infinity, and log2x moves closer to infinity as well. As a result, y becomes closer to infinity as x gets closer to positive infinity. The following can be written:

lim x→∞ 3 log2x - 5 = ∞

Similar to how log2x approaches negative infinity, the complete phrase 3 log2x also does as x approaches 0 from the right. Hence, when x moves towards 0 from the right, y moves towards negative infinity. The following can be written:

lim x→0+ 3 log2x - 5 = -∞

Step-by-step explanation:

To find the solutions to the equation x^3 + 2x^2 - x - 2 = log(x + 3), we need to find the points of intersection of the graphs of the two functions f(x) = x^3 + 2x^2 - x - 2 and g(x) = log(x + 3).

The statement that describes the relationship between the graphs and the solutions is:

The solutions are the x-coordinates of the points of intersection of the graphs.

This is because the solutions to the equation are the x-values where the two graphs intersect. At these points of intersection, the y-coordinates of the graphs will be equal, meaning that the left-hand side of the equation (f(x)) and the right-hand side of the equation (g(x)) will be equal. Therefore, we need to find the x-values where f(x) = g(x) in order to find the solutions to the equation.

To visualize this, we can graph the two functions on the same coordinate plane and look for the points where they intersect. The x-coordinates of these points will be the solutions to the equation.

The y-intercepts of the graphs (if they exist) have no relation to the solutions of the equation, as they are simply the points where the graphs cross the y-axis (i.e. where x = 0). Similarly, the x-intercepts of the graphs (if they exist) are not necessarily related to the solutions of the equation, as they only indicate where the graphs cross the x-axis (i.e. where y = 0).

Exponentiation, sometimes referred to as "b raised to the nth power," is a mathematical operation that includes two numbers: a base number, b, and an exponent, or power, n. It is represented by the sign bn. A number's exponent reveals how many times it has been multiplied by itself. For instance, the number 2-3 (written as 23) means 2 × 2 x 2 = 8. 2 + 3 = 6 does not equal 23. Remember that an integer multiplied by one equals itself. Exponents are a method for expressing large numbers as powers. The amount that shows how many times a number has been multiplied by itself is called an exponent.

An equation that sets a point on a curve at the same distance from both a fixed point and a fixed line is known as a parabola. The focus and directrix of a parabola are its fixed point and fixed line, respectively. Another important thing to keep in mind is that the fixed point does not lie on the fixed line. Every position that is equally far from the focus and directrix of two given points is said to be the locus of a parabola. The vertex of a parabola is the location where it turns sharpest. A parabolic function has a maximum value if it is shaped like a "," else, it has a minimum value.

The roots of the parabola are the coordinates where the graph intersects the x-axis (y = 0).

As you can see, the vertex of the graph is above the x-axis, and opens down, meaning that there are two roots for the graph.

Points of intersection: (2,0),(4,0)
