a small rural town has experienced a population decrease at a rate of 25 people every 5 years since 1970. if the population of the town in 1970 was 250, which of the following equations represents the town’s population as a function of time? (assume 1970 is represented by x = 0, 1971 is represented by x = 1, and so on).
a.
y = –5x + 250
b.
y = –25x + 250
c.
–5x + y = 250
d.
–x – 25y = 250

A (tested this and was Correct)

beware there's a similar question but not the same  equations

Step-by-step explanation:

slope of a line = difference in y

or

difference in x (or rise over run) = -25 / 5  slope m = -5

when x = 0 (that is the year 1970), the population is 250.

x = 0 represents the y-intercept.

so the answer choice could have the slope = -5 and y-intercept = 250

which leads to A  y = –5x + 250

i dont have an answer

step-by-step explanation:

d) by the cross product property, ab^2 = bc multiplied by ad

step-by-step explanation:

we are given

in the given triangle abc

angle a is 90° and segment ad is perpendicular to segment bc

we can see that

triangle(abc) and triangle(abd) are similar because they have common side and same angle (90 degree)

so, triangles(abc) and abd are similar

since, they are similar

so, the ratio of their sides must be equal

we get

now, we can cross multiply

and we get

so, this could be step to prove it
