Los divisores de 100 son tambien divisores de 50 ?
sergiy2304 [10]

Answer:

La afirmación es falsa, no todos los divisores de 100 son divisores de 50, ya que solo se toman en cuenta sus divisores comunes, los cuales son todos los divisores de 50. Expresamos a 100 en sus factores primos: 100 = 2 · 2 · 5 · 5 = 2² · 5² Divisores de 100: {1, 2, 4, 5, 10, 20, 25, 50, 100}

What is the equation of the line that passes through the points (0,4) and (3,-2)?
Nadusha1986 [10]

***NOTE: Please check that you wrote the numbers in the question/answer choices correctly. The answer to this problem doesn't match the answer choice. Thank you!

Remember that the slope intercept formula is:

y = mx + b

m is the slope

b is the y-intercept

First let's find the slope (m)

The formula to find slope using two points is

\frac{y_{2}-y_{1}}{x_{2}-x_{1}}

In this case...

y_{2} =-2\\y_{1} =4\\x_{2} =3\\x_{1} =0

^^^Plug these numbers into the formula for slope...

\frac{-2-4}{3 - (0)}

\frac{-6}{3}

-2

^^^This is your slope

Here is what we have so far for the slope intercept formula:

y = -2x + b

Now we must find b

To do that you must plug in a point the line goes through in the x and y of the equation, then solve for b

For this explanation we will use the point (0,4) although you could also do it with point (3, -2) and you should get the same answer  

4 = -2(0) + b

4 = 0 + b

4 = b

NOTE: For this particular problem you wouldn't technically need to go through the steps above to find b. In this case one of the points given, (0, 4) is already the y-intercept of the line (b)

y = -2x + 4

Hope this helped!
