The hypotenuse of the two triangles have the same slope because they are in the same straight line and the slope of a straight line is constatn.
You can prove that in this way:
slope = rise / run = Δy / Δx
For the upper triangle: slope = (4 - 2) / (8 - 4) = 2 / 4 = 1 / 2
For the lower triangle: slope = (-1 - (-5)) / (- 2 - (-10)) = 4 / 8 = 1 / 2
So, this proves that the two slopes are the same: 1 / 2
Step-by-step explanation:
he has $100 total.
he breeds $65 of that just for the game system.
that leaves 100-65 = $35 for games.
since each game costs $5, he can buy maximum 35/5 = 7 games.
Answer:
rational
Step-by-step explanation:
its decimal expansion terminates after 9 and it can also be represented as fraction.
Answer:
y = -11/12x + 4
Step-by-step explanation:
(-12,15) and (0.4)
4 - 15 = -11
0 -(-12) = 12 (since minus a negative = positive)
-11/12
Then just put the numbers.
15 = -11/12(-12)
15 = 11 + b
4 = b
Additional Information:
Slopes are really fun to do, but they get tricky and confusing. By the way, I am 14 years old and I did slopes, and I'm not the best at this, so I might be wrong. :( Don't hate me.
Answer:
56.52
Step-by-step explanation:
1. multiply your r by 2
so 9*2= 18
2. multiply that by pi, which you substitute 3.14 in for
so 18*3.14=56.52
