√(-1) is an imaginary number.

There are no real numbers that satisfy the equation  x = √-1.

A number that produces a negative square root is referred to as an imaginary number. An imaginary number, which has no real-world equivalent, is essentially the square root of a negative number.

Given:

We know that the value of √(-1) is i (iota) which is imaginary number.

So, √(-1) is an imaginary number.

Now, Negative numbers don't have real square roots since a square is either positive or 0.

So, x = √-1 have no real solution.

Now, x² = -1 again have no real solution because

x = √-1 and , Negative numbers don't have real square roots.

Answer: B, the second answer is correct.

Step-by-step explanation: Hope it helps, mark brainliest and give thanks please!

Answer:

y is x - 5.

Step-by-step explanation:

x - y = 5
x = y + 5
we can isolate y by subtracting 5 from both sides of the equation:

x = y + 5
x - 5 = y

Therefore, the solution for y is x - 5.

Rachel rode her bike a total distance in miles over the course of two days, as shown by the expression: -5x + 168.

Let x be the duration of Rachel's bicycle ride yesterday.

Distance = speed * time

Thus, the equation becomes.

= 9x + 14(12 - x)

On solving;

= 9x + 168 - 14x

=-5x + 168

For a savings account with an initial deposit of $425.00, the account balance after 9 years if the account earns 2.7% simple interest annually is

The account balance is solved by adding the initial deposit to the simple interest.

The simple interest is solved using the simple interest formula

The formula is stated as

Simple interest = Principal *  time *  rate / 100

In the problem the give data include

principal = $425.00

rate= 2.7%

time = 9 years

plugging in the values

Simple interest = Principal *  time *  rate / 100

Simple interest = 425 * 9 * 2.7 / 100

Simple interest = 10327.5 / 100

Simple interest = 103.275

The account balance

=  initial deposit + simple interest

= 103.275 + 425

The center of the ellipse is (2, -8).

The endpoints of the major axis are 10 units from the center.

The endpoints of the minor axis are 9 units from the center.

To graph the ellipse, connects (2, 2), (11, -8), (2, -18) and (-7, -8) with  smooth curve.

What is ellipse?

An ellipse in mathematics is a plane curve that has two focal points and is such that the sum of the two distances from any point on the curve to the focal points is a constant. It generalizes a circle, a special kind of ellipse in which the two focal points coincide.

Given:

The equation of ellipse is,

[tex]\frac{(x-2)^2}{81}+(\frac{(y+8)^2}{100}=1[/tex]

Since, the general form of ellipse is,

[tex]\frac{(x-h)^2}{a^2}+\frac{(y-k)^2}{b^2}=1[/tex]

where,

(h, k) is the center of ellipse

a is the minor axis

b is the major axis.

Here (h, k) = (2, -8) is the center of the ellipse.

9 is the minor axis and 10 is the major axis of the ellipse.

Also the graph of ellipse connects (2, 2), (11, -8), (2, -18) and (-7, -8) with  smooth curve.

Hence,  the center of the ellipse is (2, -8).

The endpoints of the major axis are 10 units from the center.

The endpoints of the minor axis are 9 units from the center.

To graph the ellipse, connects (2, 2), (11, -8), (2, -18) and (-7, -8) with  smooth curve.

The likelihood of choosing a green marble is unlikely.

Probability is used to determine how likely it is that a random event would happen. The probability that a random event occurs lie between 0 and 1.  The more likely the event is to happen, the closer the probability value would be to 1. The less likely it is for the event not to happen, the closer the probability value would be to zero.

The probability of picking a green marble is 1/4 or 0.25. 0.25 is less than 0.5. This means it is unlikely the event would occur.

Linear equation: If the maximum power of the variable/symbol in an equation is one, then the equation is called a linear equation.

An example of a linear equation is x + y = 10.

Definition of Degree: The maximum power in an equation of variable is known as a degree.

So, the degree of a linear equation is 1.

Linear equations are equations based on the first order. The linear equations are explained for lines in the coordinate system. When the equation has a homogeneous variable of degree 1 (i.e., only one variable), then it is known as a linear equation in 1 variable.

If a linear equation can have more than one variable. If the linear equation has two or more two variables, then it is called a linear equation with two variables, and so on.

The function that represents how many more texts that were sent this week than last week is: B. (f − g)(x) = 3x + 16.

To find the value of a given functional expression, we have to apply the basic knowledge of how to solve algebraic expressions.

For example, if we are given that (f - g)(x), it means we are to subtract the function g(x) from f(x). That is (f - g)(x) = f(x) - g(x).

Given the following functions:

Number of texts sent this week is represented as the function, f(x) = 8x + 14

Number of texts sent last week is represented as the function, g(x) = 5x - 2.

Number of texts that were sent this week than last week = (f - g)(x)

(f - g)(x) = (8x + 14) - (5x - 2)

(f - g)(x) = 8x + 14 - 5x + 2

(f - g)(x) = 3x + 16

from the given option the slope of the line -5/2 is shown by the equation   [tex]$y=-\frac{5}{2} x-4$[/tex]that is option B).

An indication of how steep a line is is its slope. When calculating slope mathematically, "rise over run" is used (change in y divided by change in x). Measured by slope, a line's steepness. The slope increases in steepness as it gets larger. It becomes flatter the smaller the slope. Along with indicating whether a line is going up, down, horizontal, or vertical, slope also indicates the direction of the line.

From the given option the slope of the line [tex]$-5 / 2$[/tex] is shown by the equation [tex]$y=\frac{2}{5} x[/tex] that is option[tex]$\mathbf{B}$[/tex] ) and this can be determined by using the slop intercept form.

Given :

Equation -[tex]$y=\frac{2}{5} x-1$[/tex]

First, determine the slope of the given line by using the slope-intercept form. The slope-intercept is given by the equation:

[tex]$$y=m x+c$$[/tex]

Now, compare equation (1) with the above equation.

[tex]& \mathrm{m}_1=\frac{2}{5} \\[/tex]

[tex]& \mathrm{c}=-1[/tex]

For a line to be perpendicular to the other line the product of the slope of both the line is equal to -1, that is:

To find the percent full of the popcorn box, we need to divide the volume of popcorn in the box by the total volume of the box, and then multiply by 100 to convert the result to a percentage.

First we need to find the total volume of the box:

V = l x w x h

V = (2 1/2 in x 2 3/4 in x 5 in) = (5/2 in x 7/4 in x 5 in) = (35/4 in^3) = 8.75 in^3

Now we can calculate the percent full:

percent = (26 in^3 / 8.75 in^3) x 100 = 2.97 x 100 = 297%

The popcorn box is 297% full.

The differential of the function y - x² sin 8x with respect to x is dy/dx - 2x sin 8x + 8x² cos 8x

To find the differential of the function y = x² sin 8x, we can use the standard notation dy/dx which represents the rate of change of y with respect to x.

To calculate dy/dx, we need to use the product rule, which states that the derivative of the product of two functions is the derivative of the first function times the second function plus the first function times the derivative of the second function.

Let z be the given function,

z= y - x² sin 8x

The derivative of x² is 2x

The derivative of sin 8x is 8 cos 8x

So,

dz/dx= dy/dx - (2x)(sin 8x) + (x²)(8cos 8x)

= dy/dx- 2x sin 8x + 8x² cos 8x
