(-2,0)
Step-by-step explanation:
intercepts at (-2,0) horizontally. look at the graph
Answer:
Not independent
Explanation:
Two events are not independent/dependent if the result of one event affects the outcome of the other. In the case above, numbers are picked without replacement, therefore if one slip is picked then the other slip will be picked(slips are picked only once not twice or more as in independent events). Events would be independent if there was a replacement.
3x-15/2=4x
3x-4x=15/2
-1x= 15/2
x= -15/2
Answer:
3x-8
Step-by-step explanation:
9x²-64 is the same as
(3x)² - 8²
now we have the difference of 2 squares, a²-b² =(a -b)(a +b), where a=3x, b=8
9x²-64 = (3x-8)(3x+8)
Answer:
A) √3
Step-by-step explanation:
The tangent of an angle can be found by dividing the leg opposite the angle over the leg adjacent to it.
So, we have to find them.
The 30-60-90 rule says that in a right triangle with the angles 30°, 60° and 90°, the sides opposite those angles will have the ratio of 1:√3:2.
That means the side adjacent to 60° is 2 units long and the one opposite is 2√3 units long.
Dividing those two gives us (2√3)/2, which can be simplified to √3.
