Using the following equation, find the center and radius of the circle: x2 + y2 +2x − 4y − 20 = 0

Step-by-step explanation:I don't say you have to mark my as brainliest but friend if it has really helped you plz don't forget to thank me...

the red lines denote the population of the bacteria after 35 hours. that would be 2,409.24. the y-intercept is the blue line which is 800 because that is the starting point. the equation used to make the graph is 800(1.032)^h, where h is the number of hours.

step-by-step explanation:

c: y > - 1/6x + 1

step-by-step explanation:

dashed line - meaning this < or > also not equal

solid line - meaning this < or > also equal

your answer is c because y > means up & it's shaded up, but y < means down

hope this ! : )
