vlada-n [284]

The value of x is less than or equal to 2.25.

<h2>Linear system</h2>

It is a system of an equation in which the highest power of the variable is always 1. A one-dimension figure that has no width. It is a combination of infinite points side by side.

<h3>Simplification</h3>

Simplification is to make something easier to do or understand and to make something less complicated.

Given

The expression is 47.75 + x ≤ 50.

<h3>To find</h3>

The value of x.

<h3>How to find the value of x?</h3>

The expression is 47.75 + x ≤ 50.

On simplifying,

47.75 + x ≤ 50

            x ≤  50 - 47.75

            x ≤ 2.25

Thus, the value of x is less than or equal to 2.25.

More about the linear system link is given below.

Two fair cubes, numbered 1 through 6, are tossed at the same time in order to advance on a game board. What is the probability t
DaniilM [7]
If the cubes are rolled independently, and assuming any face on the cube is as likely to occur as any other, then there is a 1/6 probability of rolling a 6, and rolling a 6 on both simultaneously is 1/6 * 1/6 = 1/36.

Which of the following functions have graphs that contain vertical asymptotes?
pshichka [43]
A vertical asymptotic is a point at which y approaches positive or negative infinite, or both, and y is undefined at that x value.

Of the options, the reciprocal has a vertical asymptote. When approaches zero, y approaches 1÷0, or infinite.
The logarithmic function also has a vertical asymptote at x=0. Let's use f(x) =log base 10 (x) as an example. This function describes the exponent you'd have to put on 10 to get x. When x=0, we have a bit of a problem. What power can you raise 10 to to get 0? The answer is negative infinite, which would be
1/ (10^∞) = 0.
