If the absolute value of a nonzero real number is equal to the opposite of the number, the number is __________.

positive
negative
zero
irrational

Answers

Answer 1
TBH, I'm really thinking about this one.... but I think I'd have to say that it's the negative.
Answer 2

If the absolute value of a nonzero real number is equal to the opposite of the number then the number is negative.

What is Number system?

A number system is defined as a system of writing to express numbers.

We have to find the number for the absolute value of a nonzero real number is equal to the opposite of the number

The absolute value of a number is its numerical value without regard to its sign.

So if the absolute value of a number is equal to the opposite of the number, it means that the sign of the number must be negative.

Hence, if the absolute value of a nonzero real number is equal to the opposite of the number then the number is negative.

A company sold 160 units in the last quarter of the year. Which of the following graphs represents the company's sales performance?

Answers

Final answer:

The question does not provide specific graphs to choose from for the company's sales performance. Nonetheless, a correct graph would show a point at 160 units for the last quarter of the year.

Explanation:

Unfortunately, the question as presented does not include any graphs to choose from. Ideally, the correct graph would have the last quarter of the year on the x-axis and the number of units sold on the y-axis. It would display a single point at 160 units for the last quarter. However, without specific graphs to choose from, a more detailed answer cannot be provided.

The graph which represents the company's sales performance is graph B.

Which of the following graphs represents the company's sales performance?

The last quarter of the year begins October 1st and ends December 31st.

Total units sold by the company in the last quarter of the year = 160 units

Graph 1:

October = 40 units

November = 60 units

December = 40 units

Total = 140 units

Graph 2:

October = 40 units

November = 65 units

December = 55 units

Total = 160 units

Graph 3:

October = 40 units

November = 50 units

December = 50 units

Total = 140 units

Graph 4:

October = 40 units

November = 60 units

December = 50 units

Total = 150 units

Therefore, last quarter of the year in graph B represents the company's sales.

What is the equation of the line that is parallel to the given line and passes through the point (−4,−6 )?

A. x = −6
B. x = −4
C. y = −6
D. y = −4

Answers

The question says that the line is parallel to the line above, so it is horizontal.  When the line is horizontal it will be a 'Y='  Then, you take a look at the y axis and check to see what part of the axis the line is going through.  Therefore, you can figure out that the awnser is C.  I hope this explanation helps!

we know that

The given line is parallel to the x-axis

so

the equation of the line that is parallel to the given line and passes through the point [tex](-4,-6 )[/tex] will be equal to the y-coordinate of the point

The y-coordinate of the point is [tex]-6[/tex]

therefore

the equation is

[tex]y=-6[/tex]

the answer is the option C

One variable linear equation is an equation that has a variable and the exponent number is one. Can be stated in the form:

[tex]\large{\boxed{\bold{ax=b}}}[/tex]

or

ax + b = c, where a, b, and c are constants, x is a variable

Whereas the two-variable linear equation is a linear equation that has 2 variables and the exponent is one

Can be stated in the form:

 [tex]\large{\boxed{\bold{ax+by=c}}}[/tex]

ax + by = c

x, y = variable

There are 2 general steps to solving a linear equation of one variable:

1. add or subtract both segments with the same number so that it is expected that in one segment there are only variable modifiers or constant numbers 2. Change the equation into a simple form so that the coefficient of the variable is 1

This can be done by dividing or multiplying by equal numbers

An equation will remain equivalent if both segments are multiplied or divided by the same number

In the equation

2x + 5 = 19

The right steps to complete it according to the images included are:

1. 2x + 5 = 9 ⇒ given 2. both segments are subtracted by the number 5

 2x + 5 -5 = 9-5  ⇒subtraction property of equality

3. 2x = 14  ⇒subtract 4. both segments are divided by 2 so that the coefficient x = 1

[tex]{\displaystyle  {\frac {2x} {2}}=~\frac{14}{2}[/tex]

⇒division property of equality

5. x = 7 ⇒ divide

I believe it is 64 degrees

In this problem, we want to find the measure of the third angle of the given triangle. Remember that the sum of the interior angles of a triangle is equal to 180 degrees.

Let's start off by writing an equation representing the sum of the interior angles of the given triangle.
y+79+37=180

Now, let's solve the equation for the variable 'y'.
y+79+37=180

Combine like terms:
y+116=180

Subtract 116 from both sides of the equation:
y+116-116=180-116
y=64

The measure of angle y is 64 degrees.

So first you make two isosceles triangles, one is URS and the other is UST. First find the degrees of angle RSU which is (180-120)/2=30. Then you know that TSU is 70 and then you can find angle T is 180-70*2 which is 40.

Another method, which is faster is that in a quadrilateral, all angles make 180 degrees. 120+100+100 is 320 and 360-320 is 40.

Write an equation that is linear but not standard form

Answers

Answer:

what she said is write so use it

Step-by-step explanation:

A linear equation not in standard form can be represented as y = mx + b, where 'm' is the slope and 'b' is the y-intercept. An example is y = 0.5x + 3, which graphs as a straight line with a slope of 0.5 and crossing the y-axis at the point (0, 3).

A linear equation that is not in standard form could be written as y = mx + b. This form is known as the slope-intercept form of a linear equation, where m represents the slope of the line and b represents the y-intercept, the point where the line crosses the y-axis. For example, if we choose a slope of 0.5 and a y-intercept of 3, the equation would be y = 0.5x + 3.

Simplify the expression.

what is the answer to qx + x = r

Answers

qx+x=r
undistribute x
notice we have
qx+1x=r
x(q+1)=r
divide both sides by (q+1)
[tex]x=\frac{r}{q+1}[/tex]
Final answer:

The value of x in the equation qx + x = r can be found by combining like terms and then isolating x. The solution is x = r / (q+1).

Explanation:

The equation given is qx + x = r. This equation belongs to the domain of algebra and can be simplified using the principles of solving linear equations. Let's work step-by-step to evaluate the solution to this equation:

First, we can combine like terms on the left side, meaning we can add qx and x together since they are similar terms. By factoring out x, we get x(q + 1) = r. Then, in order to solve for x, we have to divide r by the sum of q + 1. The resulting equation is x = r / (q + 1).

That is the solution to the equation.

if x = width, and its length is twice its width...that means it is 2 times its width....so the length of the rectangle = 2x

If x represents the width of a rectangle and if its length is twice its width then rectangle is 2x long.

What is Area of Rectangle?

The area of Rectangle is length times of width.

Given that x represents the width of a rectangle.

Length is twice its width

Length=2width

Length=2x

Length is nothing but how long the rectangle.

As the width of rectangle is x and length is 2x.

The area of rectangle is length times of width

Area of rectangle=Length×Width

=2x×x

=2x²

Hence,  x represents the width of a rectangle and if its length is twice its width then rectangle is 2x long.
