Answer:
x = -6
Step-by-step explanation:
Here we have an equilateral triangle. All three sides have the same length, 2. Therefore, the interior angles are all equal to 60 degrees.
Therefore, 6 - 9x = 60, and -9x = 54. Dividing both sides by -9 results in
x = -54/9, or x = -6.
3*60 = 180 minutes
80/180 = 0.44
1-0.44 = 0.56
it was a 56% decrease in commute time
The reflection across the x-axis only change the signal of the y coordinate. Hence, the new point is
.
That's false.
Let's see an instance:
10% of 300=30
20% of 100=20
It doesn't work here so it's false
