What is the Desmos Graphing App for Algebra and how do you use it. Is it a computer thing or do you download it on your phone?

Answers

Deseos Graphing is a website
But you also download the app on your phone
You put in the equation you want to see graphed

Answer:

  see below

Step-by-step explanation:

The Desmos graphing utility is available as an app for phone or tablet from the app stores for Android and Apple devices. It is available from the desmos web site by clicking on "Graphing Calculator" on the home page.

Attached is a screen-shot of the web version. Help can be found under the (?) button at upper right. I found the help to be useful when first starting or when trying to do something I haven't done before.

You can create an account, if you like, but that is not necessary to obtain all of the basic functionality.

A link for sharing a graph will be generated by clicking on the icon to its left. Graphs can also be saved for later reference, if you have an account. The link to a graph will work whether you have an account or not.

__

There are other desmos tools available, too, for general calculation, geometrical construction, and matrix manipulation. (I have not yet used those.)

_____

Desmos likes to use x and y for the independent and dependent variables, respectively. You can define something like h(t) = 5t+1 and it will graph it as though it were y=5x+1. When you click on an equation or graph, points of intersection with other graphs or with the axes will be highlighted. Clicking on those highlights will give their coordinates.

Equations don't need to be of the "y=" form. For example, you can use x^2+y^2=1 to make a unit circle. The usual math symbols work for keyboard input (* for multiplication; / for division; ^ for exponents). The tab or arrow keys move out of denominator or exponent fields. To make more complicated exponents, parentheses help.

There's so much more it can do. It is worthwhile to visit the on-line tutorial information.

3x-29=6x-7 what is x

Answers

Answer:

Step-by-step explanation:

You want to get x on one side and the constants on the other. First subtract both sides by 3x to get:

-29 = 3x - 7

Now add 7 to both sides to get:

-22 = 3x

Divide each side by 3 to get:

x = -22/3

3x-29=6x-7
-6. -6
-3x-29=-7
+29 +29
-3x=22
x=-22/3

15. Pat and Camilla are working with expressions with rational exponents. Listed below are what each
believes to be correct. Use the properties of exponents to determine the correct answer. Write
the correct answer in the space provided.

Answers

Answer:

Step-by-step explanation:

Pat believes that [tex]\sqrt{2}+\sqrt{8}=(2)(2)^{\frac{1}{2}}[/tex]

[tex]\sqrt{2}+\sqrt{8}=\sqrt{2}+\sqrt{4\times 2}[/tex]

             [tex]=\sqrt{2}+2\sqrt{2}[/tex]

             [tex]=3\sqrt{2}[/tex]

             [tex]=3(2)^{\frac{1}{2} }[/tex]

But [tex]2(2)^{\frac{1}{2}}\neq 3(2)^{\frac{1}{2}}[/tex]

Therefore, Pat's belief is not correct.

Camilla believes that [tex]\sqrt{2}+\sqrt{8}=3\sqrt{2}[/tex]

Which is correct as we have calculated above.

Therefore, [tex]\sqrt{2}+\sqrt{8}=3\sqrt{2}[/tex] will be the correct answer.

find the area of each shaded region​

Answers

For the shape on the left, you would break it down into two shapes and add them together at the end.
The top portion would be 2x2=4cm^2
To find the bottom numbers, we have one side that we know is 6, to find the other side, we know the whole side is 6 but we would subtract the 2 to make it even. That would give us 6x4. 6x4=24cm^2
Then we add both together to get the whole object’s area.
4+24=28cm^2

For the second shape, we would find the area of the large shape then find the area of the small shape. We would subtract the small shape’s area from the large shape.
8x5=40cm^2
2x3=6cm^2
40-6=34cm^2

The final answers for both shapes are 28cm^2 and 34cm^2
