The unknown number deduced by solving the equation 4x - 1 = 6x +9 is -5.

What is an equation?

A mathematical definition of an equation is a claim that two expressions are equal when they are joined by the equals sign ("=").

Let the unknown number be x.

First multiply the number by 4 = 4x

Then subtract 1 from it = 4x -1

This results in the same number as when the number is multiplied by 6 and 9 is added to it = 6x + 9.

So the equation will be -

4x - 1 = 6x +9

4x - 6x = 9 + 1

-2x = 10

-x = 10/2

x = -5

Therefore, the number obtained is -5.

The range for the following set of scores: 6, 12, 9, 17, 11, 4, and 14 is 13.

In statistics, the range is a measure of dispersion that describes the difference between the largest and smallest values in a dataset. The range is used to describe the spread of a dataset and can be a simple way to identify outliers or unusually large or small values. It is a simple measure of statistical dispersion and is most useful for interval and ratio data.

It is calculated by subtracting the minimum value from the maximum value among the data set.

range = maximum value - minimum value

The provided function, f(x)=(.8)^x, has a 20% rate of decay.

A rise in the resultant quantity for a given quantity is referred to as exponential growth, and a decrease in the resultant quantity for a given quantity is referred to as exponential decay.

given, a function  f(x)=(.8)^x. To calculate the decay rate of this function.

The exponential decay formula aids in determining the exponential drop, which is a rapid reduction over time. To calculate population decay, half-life, radioactivity decay, and other phenomena, one uses the exponential decay formula. F(x) = a (1 - r)x is the general form.

Where

a = the initial amount

1-r is the decay factor

x = time span

from the given expression,

Decay factor = 0.8

That is also equal to 1 - r

1 - r = 0.8

r  =0.2

Thus, rate of decay = r * 100%

rate of decay = 0.2 * 100 = 20%

On Monday, Evie practices 2T = 2*45 = 90 minutes.

A value or ratio that may be stated as a fraction of 100 is referred to as a percentage in mathematics. If we need to compute a percentage of a number, we should divide it by its whole and then multiply it by 100. The proportion, therefore, refers to a component per hundred. Per 100 is what the term percent signifies. The letter "%" stands for it.

Any number of equal parts is represented by a fraction, which also represents a portion of a whole. A fraction, such as one-half, eight-fifths, or three-quarters, indicates how many components of a particular size there are when stated in ordinary English.

Let's call the amount of time Evie practices on Tuesday T.

On Monday, she practices twice as long as she does on Tuesday, so she practices 2T minutes.

On Thursday, she practices the same number of minutes as Tuesday, so she practices T minutes.

On Saturday, she practices 5 fewer minutes than three times her Tuesday practice, so she practices 3T-5 minutes.

We know that Evie practices 310 minutes in total in a week.

So we can set up an equation:

T + 2T + T + 3T-5 = 310

7T-5 = 310

7T = 315

T = 45

Depending on the specific equation, we transform the sign while subtracting polynomials to either positive or negative. Learn more about subtracting polynomials, their techniques, procedures, and examples by reading on.

For instance, subtract 5x + 8y - 20z from 4x - 10y + 15z.

The polynomials should first be arranged in standard form. In this illustration, it has already been set up.

Place them horizontally in step two.

(4x - 10y + 15z) - (5x + 8y - 20z)

Step 3: By using parenthesis, modify the second polynomial's sign.
