Is A ={ x x 2 )= 4 and 3x 9 an empty set justify your answer?
The value of 'x' is not same in both cases, so this is a empty set.
How to calculate A={x x 2}=4 and 3*9 an empty set?step1
Because here square of element of set should be 4 then element should be 2 or -2 but when 2 or -2 multiplied by 3 gives 6 or - 6 which is not equal to 9. So, no element exists which can satisfy both conditions.
A={x x 2}=4 and 3x=9 is not empty set because there is no element we can say that is an empty set but there is an element, so it is not an empty set.
step2
X^2=4
Therefore only 2's square is 4
In first equation X=2
But in second equation
3x=9
Therefore here X=3
One variable has only one value
Therefore it is an empty set

Imma need some help here
Answer:
no it is not a solution
Step-by-step explanation:
to determine if (- 5, 4 ) is a solution to the system, substitute the x- coordinate x = - 5 into the right side of both equations and if the value obtained is equal to the y- coordinate y = 4 then it is a solution.
Note that this must be true for both equations
y = 3(- 5) + 19 = - 15 + 19 = 4 ← True
y = - 2(- 5) - 7 = 10 - 7 = 3 ≠ 4 ← False
thus (- 5, 4 ) is not a solution to the system of equations.

Kaj signed up for a streaming music service where there's a fixed cost for monthly
membership and a cost per song downloaded. Her total cost per month is given by
the equation c = 1.5x + 6.99, where X represents the number of songs she
downloads and c represents the total cost, in dollars and cents. What could the
number 1.5 represent in the equation?
In the equation for total cost c = 1.5x + 6.99, 1.5 represents the cost of per song downloaded.
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 ("=").
The equation for total cost per month is c = 1.5x + 6.99.
Where x represents the number of songs Kaj downloads and c represents the total cost, in dollars and cents.
So, c and x are variable components of the equation.
There are only two fixed components in the equation 1.5 and 6.99.
Since number of songs downloaded x is multiplied by 1.5, so 1.5 is the cost of per song downloaded.
Hence, 6.99 becomes the fixed monthly membership cost of the music service.
Therefore, 1.5 is cost of per song downloaded.

6² + x² = 17²
Step-by-step explanation:
Pythagoras Theorem defines the equation of opposite² + adjacent² = hypotenuse². To make it simple, it's basically base² + height² = slope². Therefore:
[tex] \displaystyle{ {x}^{2} + {6}^{2} = {17}^{2} }[/tex]
Or you can also form as

Joseph has a loyalty card good for a 20% discount at his local pharmacy. What would his total in dollars and cents be, after the discount and before tax, if the total cost of all the items he wants to buy is $42.05? Round to the nearest cent.
The total cost of good will equals to $33.64 after considering the 20% discount he had at the pharmacy.
What is a loyalty card?A loyalty card is an identity card issued by a retailer to its customers as a form of consumer incentive scheme in which credits are accumulated for future discounts with each transaction.
Now, we will have to calculate the total cost of all the items he wants to buy after considering the 20% discount.
First, we will calculate the discounted amount:
= 20% * $42.05
= $8.41
Second, we will calculate the new amount of cost:
= $42.05 - $8.41
= $33.64

Two sides of a triangle each measure 8 inches. Maria says the triangle must be isosceles. Is maria correct? explain.
Maria is not correct. Just because two sides of a triangle measure 8 inches, it does not mean that the triangle is isosceles.
An isosceles triangle is a triangle in which two sides are congruent, meaning they have the same length. However, just because two sides of a triangle have the same length, it does not necessarily mean that the triangle is isosceles.
There could be a third side with a different length. Therefore, it is a possibility that the third side of the triangle is not 8 inches, hence the triangle is not isosceles.
To confirm if a triangle is isosceles, we must measure all three sides and if two sides are congruent then it's an isosceles triangle.

Asher is painting a wall on a storage shed. He knows one can of paint covers an area of 24 square feet. Asher uses a meter stick to measure the wall, as shown. What is the fewest number of cans of paint Asher needs to paint the wall?
Therefore , the solution of the given pentagon is the wall has a square footage of 80.7293. Asher requires four cans in total.
A pentagon is what?A polygon with five sides and five angles is called a pentagon. Penta and Gonia, two words that each denote five angles, are the components of the word "pentagon." The shape is created when the sides of such a pentagon come together at their ends.
Here,
Given that a storage shed's wall has a pentagonal shape.
A pentagon's surface can be separated into two shapes. The first shape is a rectangle, while the second is a triangle.
The rectangular shape measures 1+1+1 = 3 meters in length.
(1 + 1) = 2 metres is the width.
3 x 2 = 6 square meters make up the space of the rectangle.
Three meters make up the triangle's base.
The triangle measures 1 meter in height.
The triangle's area is 1/2 base, 1/2 height, or 1/2 x 3-1, or 3/2 square meters.
The pentagon's total area is 7.5 square meters, or 6 + 3/2 square meters.
10.7639 square feet are equal to 1 square meter.
(7.5 x 10.7639) square feet are equal to 7.5 square meters.
= 80.7293 square meters
24 square feet are covered by one can of paint.
He requires 80.7293/24 = 3.36 square feet in order to cover it.
Therefore, he requires a minimum of 4 cans oil paint.

A line intersects the point and is perpendicular to y=(x / 4)-2. (4,-1). y=15-4 x is the equation for this perpendicular line.
What is the perpendicular line of the equation?In order to determine the equation for the line perpendicular to the line [tex]$y=\frac{x}{4}-2$[/tex]passing through the point (4,-1)
The slope-intercept version of the equation for the line is [tex]$y=\frac{x}{4}-2$[/tex].
Inversely, the perpendicular line has a negative slope of m=-4.
Consequently, the perpendicular line's equation is y=-4 x+a.
Using the notion that the line should pass through the specified location, we can use the formula [tex]-1=(-4) \cdot(4)+a[/tex] to determine a.
Thus, a=15. The line's equation is therefore y=15-4 x.
Lines that cross at a straight angle (90 degrees) are said to be perpendicular. Many perpendicular lines can be seen in the actual world. Examples include the edges of a set square, a clock's arms during particular times of day, the corners of a blackboard, a window, and the Red Cross emblem.

Therefore ,as a result, ABC is equivalent with XYZ, which is the answer to the triangle problem that was presented.
Tell us about the triangle.Given its three sides and three vertices, a triangular is a polygon. This geometric shape is fundamental. Triangle ABC is a triangle that has the points A, B, and C as its corners. In geometric shapes, when four pieces are not collinear, a single plane and triangle are obtained. Polygons include triangles since they have three sides and a top right corner.

Therefore,
∠ A = ∠X because ABC is identical with XYZ.

Does standard form have to be between 1 and 10?
No, standard form does not have to be between 1 and 10. Standard form refers to a way of writing a number in which the number is expressed as a decimal between 1 and 10, multiplied by a power of 10.
THE STANDARD FORMStandard form, also known as scientific notation, is a way of writing a number that is a product of a decimal between 1 and 10, and a power of 10. The decimal part is called the coefficient, and the power of 10 is called the exponent.
For example, 12,000 can be written in standard form as 1.2 x 10⁴. Here, the coefficient is 1.2 (a decimal between 1 and 10) and the exponent is 4, indicating that the number is being multiplied by 10 raised to the power of 4 (10,000).
It is important to note that standard form is not limited to positive numbers and decimals between 1 and 10. A negative number or decimal less than 1 can also be written in standard form, but it would be multiplied by a power of 10 that is less than 1.
