Answer:
x < 3
Step-by-step explanation:
−4x−8>−20
Add 8 to each side
−4x−8+8>−20+8
-4x> -12
Divide each side by -4, remembering to flip the inequality
-4x/-4 < -12/-4
x < 3
Answer:
Option "d" might be 11/13
Step-by-step explanation:
Red face cards=8. ( heart and Diamond)
Remove this 8 cards from 52 cards which gives
=>44
Toal cards =52
PROBABILITY = 44/52=>11/13
<span>E = {x|x is a perfect square between 1 and 9} = {1,4
</span><span>F = {x|x is an even number greater than or equal to 2 and less than 9}
</span><span>D = {x|x is a whole number}
</span>
answer
D ∩ (E ∩ F) = 4
Answer: 
=====================================================
Reason:
Plot the points (0,0) and (r,s). You can place (r,s) anywhere you want.
Connect the two points mentioned and form a right triangle such that the segment from (0,0) to (r,s) is the hypotenuse of said right triangle.
The horizontal leg has a length of r-0 = r units, while the vertical leg will be 's' units.
Check out the diagram below.
We then apply the pythagorean theorem to say
where h is the hypotenuse. Solving for h gets us
. We only focus on the positive square root since a negative hypotenuse makes no sense.
Since we made the hypotenuse the segment with endpoints (r,s) and (0,0), this means the hypotenuse length and the distance are the same thing.
Therefore, the distance from (r,s) to (0,0) is 
As an alternative, you can use the distance formula to get the same answer. The distance formula is effectively the pythagorean theorem phrased a different way.
