Answer:
idk
Step-by-step explanation:
The slope of the line is 2
The formula for finding slope using two coordinate pairs is y-y
——-
x-x
In this case, the y values are 10 and 2, and the x values are 6 and 2. If we plug these into our formula the equation is 10-2
———
6-2
10-2 is 8 and 6-2 is 4. So 8 divided by 4 would equal 2
Problem: In chess, Justin won 20 games, tied 8 games, and lost 14 games last year. What is Justin’s ratio of total games to tied gamesSolutions:=> There are a total of 20 games=> 8 of them were tied=> 14 games were lost.Now, let's find the ratio of the tied games to the total games.=> Since the total game is 20 and the tied games are 8, therefore the ratio will be:<span>=> 8 : 20, where 8 are the tied games and 20 is the total</span>
<u>Answer</u> : The demonstration is below :)
Step-by-step explanation :
<u>We use Pythagoras' </u><u>theorem </u><u>:</u>
- In the triangle ABC we have :
AB² = AC² - BC² = 15² - 9² = 144 = 12²
- In the triangle ABD we have :
DB² = AD² - AB² = 13² - 12² = 5²
cos(a) = BD/AD = 5/13
