Does this graph represent a function ? Why or why not ?

Mathematics

Answer:

The answer would be (B

Step-by-step explanation:

If you are insecure whether your relation is a function or not you can draw a vertical line right through your graph. If the relation is not a function the graph contains at least two points with the same x-coordinate but with different y-coordinates.

The relation portrayed in the graph to the left shows a function whereas the relation in the graph to the right is not a function since the vertical line is crossing the graph in two points.

Answer:

D) It passes the horizontal line test

Step-by-step explanation:

In order for a line to represent a function it must pass the vertical line test.

To apply the horizontal line test, take a pencil and hold it vertically. Then, move it across the graph from left to right. If it intersects the line at 1 point everywhere along the line, then it is a function (functions can only have 1 Y value for every X value).

Answer:

1) Appliances are connected in parallel

2) Appliances are connected in parallel

3) Appliances are connected in parallel (because in house , appliances are connected in parallel)

4) Advantage :- Such kind of connections assures that even if one or more appliances stops working , the working of other appliances will remain unaffected because in such connections , voltage remains constant

Disadvantage :- Such circuits can draw more power which leads to high bill charges on electricity. Also such connections need more wiring.

The general form of a circle is given as x^2 + y^2 + 4x - 12y + 4 = 0.
stepan [7]
If you can rewrite the formula as (x-a)² + (y-b)² = r², the center is at (a,b) and the radius is r.

If you work out this equation, and map it to the original, you will find that the +4x term hints that a = 2 (double product) and -12y hints that b=-6, and r=6.

So, the formula can be written as (x+2)² + (y-6)² = 6² and the center is at (-2,6) and the radius is 6.

What is the value of x in the equation 2x + 3y = 36, when y = 6?
amm1812

Answer:

9

Step-by-step explanation:

When plugging 6 in for y, you get  

2x + 3(6) = 36

You have to multiply 3 and 6, getting

2x + 18 = 36.

Now, you subtract 18 from both sides to isolate the x variable, getting

2x = 18

Now, you divide 2 from both sides because we want x standing by itself, getting

x = 9

Therefore, your answer is 9.

Hope this helped

ps accepting brainliest ;)

Its the third option y-9=-1/4(x+2) because the equation for point slope form is y-y1= m(x-x1) so because there is a negative 2 it is a positive 2. Remember a negative minus a negative is a positive. Hope this helped :)!
