Answer:
A. Z = 2 + N13
Step-by-step explanation:
Let's solve your equation step-by-step.
0=z2+4z−9
Step 1: Subtract z^2+4z-9 from both sides.
0−(z2+4z−9)=z2+4z−9−(z2+4z−9)
−z2−4z+9=0
For this equation: a=-1, b=-4, c=9
−1z2+−4z+9=0
Step 2: Use quadratic formula with a=-1, b=-4, c=9.
z=
−b±√b2−4ac
2a
z=
−(−4)±√(−4)2−4(−1)(9)
2(−1)
z=
4±√52
−2
z=−2−√13 or z=−2+√13
It is correct because if you do the math you will come up with 48 - 24k = 48 - 24k
3:40
1:13
it would be 13.3 repeated but since you round to the nearest dollar it would be 13. All I did was divide 40 by 3.
Answer:
The 12th term in the sequence is b(12)= -26
Step-by-step explanation:
For the 12th term, that means we need to find what the value of b is when n=12
To find b:
- Substitute all 'n' with 12 (since its the 12th term)
b(n)= -4-2(n-1)
b(12)= -4-2(12-1)
- Solve the equation in order of BEDMAS (aka PEDMAS)
b(12)= -4-2(11)
= -4- (2*11)
= -4-(22)
= -26
The 12th term in the sequence is b(12)= -26
