Find the slope of the line through the pair of points. A(2, –3), P(2, 9)
Flauer [41]
The slope: m=\dfrac{y_2-y_1}{x_2-x_1}

A(2;-3)\to x_1=2;\ y_1=-3\\P(2;\ 9)\to x_2=2;\ y_2=9\\\\subtitute:\\\\m=\dfrac{9-(-3)}{2-2}=\dfrac{12}{0}!!!

<span>The denominator can not be <span>zero!

Conclusion: The slope is undenfined.

A chemist is using 373 millimeters of a solution of acid and water.if 19.9 percent of the solution is acid how many millimeters
vovikov84 [41]

There are 74.227 milliliters of acid in the solution.

Explanation:

  • The total amount of liquid is 373 milliliters. This is both the acid and water combined i.e amount of liquid + amount of acid = 373 milliliters
  • If 19.9% of this is acid it means 19.9% of the the entire 373 milliliters is acid. So we calculate how much 19.9% of 373 milliliters is.
  • 19.9% of 373 milliliters = 0.199 × 373 = 74.227 milliliters. So 74.227 milliliters of the entire solution is acid.
