Answer:
A
Step-by-step explanation:
permutation are variations of a problem, but they are collecting movies and selecting 4 out of the 20 so it is combination
No they are not equivalent
To see if it’s linear use a pencil and see if any lines touch more than one point (just look up pencil line test) and 1-4 just draw out a graph (and since it goes up to hundred don’t count by 1s count by 10 or or something
Hope you kind of get the idea sorry I’m not the best at explaining stuff :)
Since this is a right triangle the angle opposite the side 17 is also 45°
So this can be solved in two ways...
The Law of sines...
x/sin90=17/sin45
x=17/sin45
x≈24.04 to nearest hundredth
or by realizing that both sides are 17 because they are both opposite 45° angles then the hypotenuse x is
x=√(2*17^2)
x=√578
x≈24.04
2x - 17y = 13
Since we don't have the the value of x we would set x = 0
2(0) - 17y = 13
And solve
-17y = 13
y = -13/17
You would do the same if you're solving for x
2x - 17(0) = 13
2x = 13
x = 13/2
(I'm not sure if you are missing anything but based on the information provided this is how I would solve it.)
