PLEASE HELP ASAP!!!

Mathematics
1 answer:
Alona [7]2 years ago
8 0

Answer:

Here is what I think:

Addition and Multiplication are very similar. Multiplication is just repeated addition. If you do 3*2 its just adding 3, 2 times to each-other. The same goes for division. Its repeated subtraction. 15/3 If you subtract 3 from 15 how many times can you do it. There are also differences though. Multiplication is usually used to calculate different things though. It can calculate area and volume while addition usually doesn't. Division is used to find how much of something can fit into something. But subtraction usually is only used for subtracting other things. Those are similar things and different things for this.

Can somebody please solve this? It's a coordinate thingy
statuscvo [17]

Answer:

Coordinates involve two points. (x,y)

Too find a pair (coordinate), use the x and y lines on the graph and see where the point falls.

For example

Point A is number <em>1</em><em> </em><em>on</em><em> </em><em>the</em><em> </em><em>y</em><em> </em><em>axis</em>

<em>number</em><em> </em><em>-</em><em>4</em><em> </em><em>on</em><em> </em><em>the</em><em> </em><em>x</em><em> </em><em>axis</em>

<em>So</em><em>,</em><em> </em><em>you</em><em> </em><em>would</em><em> </em><em>write</em><em> </em><em>the</em><em> </em><em>coordinate</em><em> </em><em>out</em><em> </em><em>at</em><em> </em>

<em>(</em><em>-</em><em>4</em><em>,</em><em>1</em><em>)</em>

The y axis values are the second point, so after you plot all of letters, use the y axis numbers and number them from least to greatest so you can find the mystery word.

What two numbers add to 13 but multiply to negative 12?
Phoenix [80]

9514 1404 393

Answer:

  13.8654599313 and -0.8654599313

Step-by-step explanation:

If one of the numbers is x, then the other is 13-x, and their product is ...

  x(13 -x) = -12

  x^2 -13x = 12 . . . . multiply by -1 and simplify

  x^2 -13x +6.5^2 = 12 +6.5^2 . . . . complete the square

  (x -6.5)^2 = 54.25

  x -6.5 = √54.25

  x = 6.5 +√54.25 ≈ 13.8654599313

and the other number is ...

  13 -x = 13 -13.8654599313 = -0.8654599313

The two numbers are 13.8654599313 and -0.8654599313.
