Answer:
A. 9
Step-by-step explanation:
A counterexample shows that one side is true while the other is false
x>7 and x>11
sub in the answers
9>7 and 9>11 -this is true for the first half but false for the second
5>7 and 5>11 -this is false for both
13>7 and 13>11 -this is true for both
15>7 and 15>11 -this is true for both
Answer A is correct as it proves the statement to be incorrect
Answer: 1 is not, 2 is, 3 is, 4 is, 5 is, 6 is not
Step-by-step explanation:
1 is not because 2 has two arrows coming off of it and each input can only have one output. 6 is not because if you draw a line down the graph it will hit the figure more than once( this is called the pencil drop test)
A(0,0) A'(2,1)
distance(AA') = √(2^2 + 1^2)
= √5
= 2.24
answer
Distance AA' = √5 or = 2.24
Answer:
1,2,4,5,6
Step-by-step explanation:
Answer:
e = 9
Step-by-step explanation:
ok e is just x, so we have to get it alone
4e - 10 = 2e + 8
We move the 2 since its smaller than the 4, and we move it two the other side. 4-2=2 so the new e is 2, now that 8 is alone (since we moved the 2), we cant be having the e with the -10... like this..
2e - 10 = 8, so we now add 10 so it can go with the 8, the new equation is this..
2e = 18
18/2 = 9
simple explanation
4e - 10 = 2e + 8
2e = 18
e = 9
(does that make sense)
