kherson [118]

Answer:

0 People initially had the cold.

6 People will have it after 2 days.

Step-by-step explanation:

To find out how many people had it initially, plug 0 in for x (implying 0 days later.)

C= 1*3(0)

C= 1*0

C=0

Nobody had the cold initially.

To find out how many people had it after 2 days, plug 2 in for x. (implying 2 days later.)

C= 1*3(2)

C= 1*6

C=6

Therefore 6 people had the cold after 2 days.

I hope this helps!

5. Solve the equation z^2 + 4z - 9 = 0 by completing the square.
Luba_88 [7]

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
