let speed of water leaking out = x/h

water left in the tank after 24h=20-(speedxtime)

=20-(24x)

=14

20-24x=14

24x=6

x=1/4

Find the gradient of the line segement between the points (0,-6) and (2,-16)
yulyashka [42]

answer = 5

Slope, sometimes referred to as gradient in mathematics, is a number that measures the steepness and direction of a line, or a section of a line connecting two points, and is usually denoted by m. Generally, a line's steepness is measured by the absolute value of its slope, m. The larger the value is, the steeper the line. Given m, it is possible to determine the direction of the line that m describes based on its sign and value:

A line is increasing, and goes upwards from left to right when m > 0

A line is decreasing, and goes downwards from left to right when m < 0

A line has a constant slope, and is horizontal when m = 0

A vertical line has an undefined slope, since it would result in a fraction with 0 as the denominator. Refer to the equation provided below.

Slope is essentially change in height over change in horizontal distance, and is often referred to as "rise over run." It has applications in gradients in geography as well as civil engineering, such as the building of roads. In the case of a road the "rise" is the change in altitude, while the "run" is the difference in distance between two fixed points, as long as the distance for the measurement is not large enough that the earth's curvature should be considered as a factor. The slope is represented mathematically as:

m =

y2 - y1

x2 - x1

(4m+7n-6p)-(2m-3n-4p)
Vanyuwa [196]

Answer:

2m + 10n - 2p

General Formulas and Concepts:

<u>Pre-Algebra</u>

  • Distributive Property

<u>Algebra I</u>

  • Terms

Step-by-step explanation:

<u>Step 1: Define</u>

(4m + 7n - 6p) - (2m - 3n - 4p)

<u>Step 2: Simplify</u>

  1. Distribute negative:                    4m + 7n - 6p - 2m + 3n + 4p
  2. Combine like terms (m):             2m + 7n - 6p + 3n + 4p
  3. Combine like terms (n):              2m + 10n - 6p + 4p
  4. Combine like terms (p):              2m + 10n - 2p

If you know the rate of a water leak in gallons per hour, how can you find the number of hours it takes for 1 gallon to leak out
marusya05 [52]
You could make a small (easily repaired) leak and watch it for the amount of time you need to conclude what you need to.
