The population density D (in people/mi2) in a large city is related to the distance x (in 5000x
miles) from the center of the city by D =
x2+36
a) What eventually happens to the density?
b) In what areas of the city does the population density exceed 400 people/mi??

i have no clue at all sorry

step-by-step explanation:

i would need to see the dot plot : )

y = 2x

step-by-step explanation:

if you divide each number in the sequence, you'll see that they all have a multiple factor of 2. each number in the series, and any other numbers which may continue, will be multiplied by 2. therefore, y is the next number in the sequence, and x is the current one, so, our formula will be y = 2x.

5x + 5

step-by-step explanation:

you should always add the diagrams and graphs we cannot see. this particular question is kind of borderline because we can make a graph for you.

(f + g)x = -x^2 +3x + 5 + x^2 + 2x

(f + g)x = 5x + 5

the graph of z = 5x + 5 is shown below. always use desmos when in doubt.
