(x,y)
sub those for x and y and see if you get a true statement
(2,-8)
6(2)+-8=-4
12-8=-4
4=-4
fasle
(2,8)
6(2)+8=4
12+8=4
20=4
false
(1,2)
6(1)+2=4
4+2=4
6=4
false
(1,-10)
6(1)+-10=4
6-10=-4
-4=-4
true
ANSWER IS D
E) 12 minutes
A normal curve has approximately 95% of graph between mean - 2sd and mean + 2sd
So 95% of the times will be between 0 and 12 minutes. 6 - 2x3 to 6 + 2x3
2.5% will take over 12 minutes
Strangely 2.5% will also take less than 0 minutes to process which shows the normal curve is not perfect in this example.
4 packs of notepads and 5 packs of sticky notes
Explanation: if he needs the same number of both he needs to find the first number that 4 and 5 both go into. 4 x 5 = 20 so this is the least common multiple
Answer:
A. H<0
Step-by-step explanation:
<em>Add by 4 from both sides of equation.</em>
<em>-4+4>-4+h+4</em>
<em>Simplify.</em>
<em>0>h</em>
<em>Then, switch sides to find the answer.</em>
<em>h<0</em>
<em>h<0 is the correct answer.</em>
