What is the graph of the inequality 3x+2y>-5
Doss [256]

Answer:

The graph with solution is shown below.

Step-by-step explanation:

We need to find the x-intercept and y-intercept for given equation.

For  x-intercept , substitute y=0

Considering inequality sign as equality and simplifying,

3x+2y=-5\\3x+0=-5\\x=-\frac{5}{3} , point is (-\frac{5}{3} ,0)

Similarly,

For y-intercept , substitute x=0

We get,

3x+2y=-5\\0+2y=-5\\y=-5/2 , point is (0,-\frac{5}{2})

We locate this two points on the graph now and join them.

The joining line will be dotted as the inequality has just 'greater than' symbol. The region above the dotted line is the solution to graph.

Which of the following are examples of irrational numbers?
andreyandreev [35.5K]
√4 + √16 = 2 + 4 = 6   <--- rational
√5 + √36 = √5 + 6   <--- irrational 
√9 + √24 = 3 + √24   <--- irrational
2 * √4 = 2 * 2 = 4   <--- rational 
√49 * √81 = 7 * 9 = 63   <---rational
3√12 = 3√(4 * 3) = (3 * 2)√3 = 6√3    <---irrational

Hope this helps ^-^

Heelppppppppp!!!!! Please?!
Gre4nikov [31]

To calculate h evaluate inside the square root before taking the square root

h = √(7² - 3.5²) = √(49 - 12.25) = √36.75 = 6.06 ( to 2 dec. places)

Sylvie folds a large piece of paper in half. The fold divides the paper into two equal parts. She folds it in half again. When s
Nikolay [14]
Each time you fold a paper it will double the amount of parts. When you think about it, it's just multiplying by 2 a bunch of times.

One fold is 2 times 1, which is 2.
The second fold is 2 times 2, which is 4.
The third fold is 4 times 2, which is 8.

Using this process, we can simplify that into exponents. If the amount of times you fold is x and the parts double for each fold, then the amount of parts can be represented by:

2^{x}

So if the amount of parts is given and we need the amount of folds, just keep doubling until you get to 64. The amount of times you doubled is the number of times Sylvie folded.

Later you will learn that the opposite of an exponent is a logarithm, which would look like this:

log_{2}(64) = ?

But don't worry about that yet.

Jake says adding 0 to an addendum does not change a sum. Is he correct
siniylev [52]
Nothing changes if you don't add anything. 

Example:

10+10=20
20+0=20
 
nothing changes.
