Answer:
= - 4n + 6
Step-by-step explanation:
There is a common difference between consecutive terms of the sequence
- 2 - 2 = - 6 - (- 2) = - 10 - (- 6) = - 14 - (- 10) = - 4
This indicates the sequence is arithmetic with explicit formula
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
here a₁ = 2 and d = - 4 , then
= 2 - 4(n - 1) = 2 - 4n + 4 = - 4n + 6
Answer:1.8
Step-by-step explanation:
Answer:
8. y = x + 3 y = 2x + 4. SOLUTION: The graphs intersect at one point, so there is ... 10. y = 6 y = 3x + 4. SOLUTION: The two equations intersect at exactly one ... 18. y = x − 6 solution. The lines intersect at . 18. y = x − 6 y = x + 2. SOLUTION: ... 2x + 2y = 6 ... 28. y = 6x + 6 ... of the following systems of equations doesn't belong.
Step-by-step explanation:
Answer:
20
Step-by-step explanation:
Y varies inversely with x
y = k/x
when y = 0.5, x = 3
0.5 = k/3
k = 0.5 x 3 = 1.5
k = 1.5
y = 1.5/x or y = 3/2x
