The population of a country is initially two million people and is increasing at a rate of 4% per year. The
country's annual food supply is initially adequate for four million people and is increasing at a constant
rate adequate for an additional 0.5 million people per year.
a. Based on these assumptions, in approximately what year will this country first experience shortages of
food?
b. If the country doubled its initial food supply and maintained a constant rate of increase in the supply
adequate for an additional 0.5 million people per year, would shortages still occur? In approximately
which year?

answer: a

step-by-step explanation:

if xy ~ yz therefore xy would be the same length as yz

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !

the equation of the parallel line would be y = 2x + 9

step-by-step explanation:

to start we need to find the slope of the original line. we can do that by looking at the coefficient of x, which is 2

since the slope of the original line is 2 and parallel lines have the same slope, we know the new line will also have 2 slope. now we can use that along with the point given in point-slope form to get the find equation.

y - y1 = m(x - x1)

y - 5 = 2(x + 2)

y - 5 = 2x + 4

y = 2x + 9
