Answer:

m = 10

Step-by-step explanation:

Given w is inversely proportional to m then the equation relating them is

w = \frac{k}{m} ← k is the constant of variation

To find k use the condition w = 8, m = 25 , then

8 = \frac{k}{25} ( multiply both sides by 25 )

200 = k

w = \frac{200}{m} ← equation of variation

When w = 20 , then

20 = \frac{200}{m} ( multiply both sides by m )

20m = 200 ( divide both sides by 20 )

m = 10

6x - 2y = 5
laiz [17]

Answer:

The given system has NO SOLUTION.

Step-by-step explanation:

Here, the given system of equation is:

6 x -  2 y = 5     .......... (1)

3 x  - y = 10          .... (2)

Multiply equation 2 with (-2), we get:

3 x  - y = 10     ( x -2)

⇒  - 6 x + 2 y = - 20

Now, ADD this to equation (1) , we get:

6 x - 2 y  - 6 x + 2 y  = 5 - 20

or, 0 = - 15

WHICH IS NOT POSSIBLE as 0 ≠ -15

Hence, the given system has NO SOLUTION.

Find the inequality represented by the graph. Thanks!<br><br> (plz no spam...)
nikitadnepr [17]

Answer:

y > (1/3)x - 3.

Step-by-step explanation:

The graph of a line can be written in y = mx + b form where b is the y-intercept and m is the slope.

In the image, the slope of the graph from the given points is 1/3.

In the image, the y-intercept is -3.

Therefore, the line is y = (1/3)x -3. However, we aren’t done yet! This is an inequality, not an equation!

We see the line isn’t dotted, so that means it must be > or <.

We substitute the point (0,0) into the line equation we got and find that 0 > (1/3)(0) - 3 = -3. Since (0,0) is part of the inequality, we have that y > (1/3)x - 3.

I hope this helps! :)
