<span>So there are 4 books
=> 1 physics
=> 1 chemistry
=> mathematics
=> Biology
These books needs to be place on a shelf.
Now, let’s find the probability of mathematics book to be placed on top.
Let’s analyze the problem
Probability => 1 mathematics book / 4 total books
P = Probability
P = 1 / 4
P = ¼ or 0.25
Thus, the probability of mathematics book to be placed on top inside the shelf
approximately is ¼ or 0.25.</span>
Slope formula : (y2 - y1) / (x2 - x1)
(4,1)...x1 = 4 and y1 = 1
(-1,-5)...x2 = -1 and y2 = -5
now we sub and solve
slope = (-5 - 1) / (-1 - 4) = -6/-5 = 6/5 <==
Got you fam. or whatever you kids say these days....
Reflect the rectangle across the y axis
Move +3 units x (3 units to the right _)
Rotate -90°
Move -3 units y (3 units down)
Answer
4. - x ^ 2 + 13x - 42 <= 0524211r
5. x ^ 2 - 11x - 42 < 0
16 - x ^ 2 + 9x - 8 <= 0
17. x^ 2 -11x+80<0
18. - x ^ 2 + 3x + 4 <= 0
19. x ^ 2 - 12x + 36 <= 0
20. 2x ^ 2 - 32x + 56 < 0
21. x ^ 2 - 10x - 96 < 0
