about 42.8 because 898 divided by 21 gives you 42.76
Y=(1/2)x^2 + 2x - 1
3x - y = 1, or y=3x-1
substitute
3x-1=(1/2)x^2+2x-1
0=(1/2)x^2-x
0=x(0.5x-1)
x=0,2
y=2+4-1=5
3(2)-1=5.
When x=2 y=5 (2,5) is one solution
when x=0, y=-1, (0,-1) is the other solution
Step-by-step explanation:
The correct answer here is 51
Answer:
so whats the question??
Step-by-step explanation:
Solution
f(n +1) = f(n) + 3
Here common difference (d) = 3. This is an arithmetic sequence.
First term f1 = -4
2nd term = f1 + 3
= -4 + 3
2nd term = -1
The 2nd term = -1
