In a science experiment, Tania uses 0.8 ounce of water to create a reaction. She wants the next reaction to be 0.1 times the siz
sergij07 [2.7K]

Answer:

0.08 ounce

Step-by-step explanation:

If the size of Tania's reaction is proportional to the amount of water used, then she can reduce the reaction size to 0.1 of its previous value by reducing the quantity of water to 0.1 of its previous value:

  0.1 × 0.8 oz = 0.08 oz

The size of Tania's reaction may depend on other factors, so changing the amound of water may have no effect whatever. If water serves as a damper on the reaction, Tania may need to increase the amount of water used.

Answer:

  y -1 = -1(x -2)

Step-by-step explanation:

The slope of the line through the two points can be found from the slope formula:

  m = (y2 -y1)/(x2 -x1)

  m = (5 -1)/(-2 -2) = 4/-4 = -1

The point-slope equation for a line through point (h, k) with slope m is ...

  y -k = m(x -h)

You have (h, k) = (2, 1) and m = -1. Putting these values into the form gives ...

  y -1 = -1(x -2)

_____

<em>Additional comment</em>

Your problem statement already has two of the three values filled in, so you only need to enter the x-coordinate of the first point: 2.
