Suppose that y varies directly with x<br> and y = 5 when x = 6. What is y<br> when x = 5?
skelet666 [1.2K]

Answer:

y=25/6

Step-by-step explanation:

We can set up a proportion!

We know that y/x=y/x because they vary directly.

So, we have 5/6=y/5. We need to solve for y.

We cross multiply and get:

6y=25

y=25/6

When x equals 5, y will equal 25/6.

Hope this helps

What is the distance between (8,-3) and (4,-7) ?​
galina1969 [7]

Answer:

The answer is

<h3>4 \sqrt{2}   \: \:  \: or \:  \:  5.656 \:  \:  \: units</h3>

Step-by-step explanation:

The distance between two points can be found by using the formula

<h3>d =  \sqrt{ ({x1 - x2})^{2} +  ({y1 - y2})^{2}  }  \\</h3>

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

(8,-3) and (4,-7)

The distance between them is

<h3>d =  \sqrt{ ({8 - 4})^{2}  +  ({ - 3 + 7})^{2} }  \\  =  \sqrt{ ({4})^{2} + ( { - 4})^{2}  }  \\  =  \sqrt{16 + 16}  \\  =  \sqrt{32}</h3>

We have the final answer as

<h3>4 \sqrt{2}   \: \:  \: or \:  \:  5.656 \:  \:  \: units</h3>

Hope this helps you
