(-y + 5a - 4) + (3y - a - 5) is simplified to 2y + 4a - 11
Answer:
-2, -4, -6, -8, -10......
Step-by-step explanation:
The sequence is in a decreasing order of -2 for the next sequence.
If the ratio is 90:3 and there are 4 groups of 3 in 12, then the ratio would then be 450:12, leaving you with 450 as the answer. Hope I helped
f(3) is equal to -101.
<u>Step-by-step explanation</u>:
- The sequence is followed by f(0)=4
- The given expression is f(n+1)= -3f(n)+1
Put n=0,
f(0+1)= -3f(0)+1
f(1)= -3(4)+1
f(1)= -12+1 = -11
Put n=1,
f(1+1)= -3f(1)+1
f(2)= -3(-11)+1
f(2)= 33+1 = 34
Put n=2,
f(2+1)= -3f(2)+1
f(3)= -3(34)+1
f(3)= -102+1
f(3)= -101
He score 48 marks.
This can be found by simply multiplying 80 by 60% (0.6). This will give you your rinal answer of 48.
I hope this helps!
