Answer:
rotate 180° on the y axis (to the right??)
X^2 - 8x-9=0
D = b^2- 4*a*c = 64- 4* (-9) = 64+36=100 =10^2
X1 = (8-10)/2 = -1
X2= (8+10)/2= 9
Answer:
45158
Step-by-step explanation:
Since the colony grows at a rate of 12%, after 2 years there will be 
bacteria. Since you probably can't have part of a bacteria, you round to 45158.
Where is the table,but this is what i did without the table .
first added all the numbers up and got 260
then i put each color and the total in fraction form
then i simplified:
yellow would be: 50/260=5/26
red would be: 45/260=9/52
blue would be: 65/260=13/52
orange would be: 40/260=4/26
green would be: 60/260=6/26
