You need to substitute the ordered pairs into the system of equations and pick the ones that makes the system of equations true:
0 < -3(0) + 2 (True)
0 ≥ 0 - 1 (True)
----------------
-4 < -3(0) + 2 (True)
-4 ≥ 0 - 1 (False)
----------------
4 < -3(1) + 2 (False)
4 ≥ 1 - 1 (True)
----------------
3 < -3(-3) + 1 (True)
3 ≥ -3 - 1 (True)
----------------
The Answer is (0,0) and (-3,3)
Answer:
n = - 1
Step-by-step explanation:
Given
- 8n + 4(1 + 5n) = - 6n - 14 ← distribute and simplify left side
- 8n + 4 + 20n = - 6n - 14
12n + 4 = - 6n - 14 ( add 6n to both sides )
18n + 4 = - 14 ( subtract 4 from both sides )
18n = - 18 ( divide both sides by 18 )
n = - 1
Answer:
The answer is 3.
Step-by-step explanation:
This is because f(-3) = -(-3) = 3.
Answer:
k = 4.
Step-by-step explanation:
An arithmetic sequence has a common difference.
So for this to be arithmetic:
k + 3 - (k - 1) = 3k - 1 - (k + 3)
k + 3 - k + 1 = 3k - 1 - k - 3
3 + 1 = 2k - 4
4 + 4 = 2k
k = 4.
The sequence is 3, 7, 11.
