How many solutions does the pair of equations y 0 and y =- 5 have class 10?

Answers

If there were two equation, one on top of the other, there would be infinitely many solutions. but here no solution

If there were two lines that intersected at one point, there would be one solution.

y=0 and y=-5 don't have any solutions. When you ask if a pair of equations have a solution, that means there is an intersection of the equations. The 2 equations will meet somewhere, and that is the solution. To find the solution, you set the equations equal to each other.

0≠-5

It is obvious that 0 and -5 are not equal to each other. Therefore, there is no solution. Also, y=0 and y=-5 are horizontal lines that are parallel to each other. They will never meet, which means there will be no intersection. No intersection means no solutions

Why does AAS congruence work?

Answers

Angle-Angle-Side is abbreviated as AAS. The triangles are said to be congruent when two angles and a non-included side of one triangle match the corresponding angles and sides of another triangle. AAS congruence may be demonstrated with a few simple methods.

When two triangles in geometry are the same size and shape, they are said to be congruent. The Angle-Angle-Side (AAS) congruence theorem is one of several approaches to demonstrate that two triangles are congruent.

According to the AAS congruence theorem, triangles are congruent if two angles and the side that connects them in one triangle are congruent with two angles and the side that connects them in another triangle. This is how this theorem is expressed:

If ∠A = ∠E, ∠B = ∠F, and AB = EF, then ∆ABC ≅ ∆DEF

In other terms, triangles ABC and DEF are congruent if two angles and the side between them in triangle ABC are equivalent to two angles and the side between them in triangle DEF.

Saha ue 3 teapoon of hot chocolate mix for every 8 ounce of milk. How many teapoon of hot chocolate mix doe he need for 48 ounce of milk?

Answers

Saha uses 3 teaspoons of hot chocolate mix for every 8 ounces of milk. for 48 ounces of milk, he needs 18 teaspoons of hot chocolate.

The problem can be solved using unitary method or using ratio.

- Unitary method

Using this method, first, compute how many teaspoons of chocolate needed for 1 ounce of milk.

8 ounces of milk need 3 teaspoons of hot chocolate. Hence,

1 ounce of milk need 3/8 teaspoons of hot chocolate

48 ounce of milk need 3/8 x 48 = 18 teaspoons of hot chocolate

- Using ratio

Let p = number of teaspoons of hot chocolate needed for 48 ounces of milk. Then,

3 : 8 = p : 48

8p = 3 x 48

p = 3 x 48/8 = 3 x 6 = 18 teaspoons

How do you know if a function is positive or negative?

Answers

A function is positive if the output values are greater than the input values and negative if the output values are less than the input values.

To determine if a function is positive or negative, you must first look at the output values of the function. If the output values are greater than the input values, then the function is positive. This means that the output values increase as the input values increase. Conversely, if the output values are less than the input values, then the function is negative. This means that the output values decrease as the input values increase. For example, if a function has an input value of 3 and an output value of 5, then the function is positive because the output is greater than the input. On the other hand, if the same function had an output value of 1, then the function would be negative because the output is less than the input. In summary, a function is positive if the output values are greater than the input values and negative if the output values are less than the input values.

What is the set of all x values?

Answers

The range is the set of all "y" values in an ordered pair, while the domain is really the set of all "x" values.

What is defined as the term called domain?

Keep in mind which ordered pairs are represented by the following symbols: (x, y).

List all the x values first from relation to determine the domain when examining a set of ordered pairs. List each of the y values first from ordered pairs to determine the range. Repeated values that fall inside the domain or range need only be listed once. Each x value in a relation must have a unique value for the y value for it to be a function.

A collection of ordered pairs isn't a function if an x value has had more than one y value associated with it, as as in the relation (4, 1), (4, 2), where the x value of 4 has y values of 1 and 2.

Thus,  If there is only one y-value for every x-value, then the relation is called a function.

What do you mean by slope?

In mathematics, a line's slope, also known as its gradient, is a numerical representation of the line's steepness and direction. Divide the difference in elevation between two points by the distance between them to find the percent slope, then multiply the result by 100. The term "rise" refers to the difference in elevation between two sites. The run is the separation between the points. Percent slope is therefore equal to (rise / run) x 100.
