A landscaper is working on a plot of land that is 409 feet above sea level on its western border. The land slopes upward from west to east on both sides of the border with a vertical change horizontal change ratio of 18 13. The expression 18 13x+992 models the elevation of the land on both sides of the​ border, with x representing distance east from the border. A neighbor directly to the west asks the landscaper to calculate the elevation of a point exactly 247 feet west of the​ border, at x=−247. Find the elevation of that point.

hey there!

if she's saving for six months, let's divide the total number we need for the trip by six, dividing it into the amount that needs to be saved for each month.

500 ÷ 6 =

she needs to save at least this amount each month, so we should use this symbol: ≥

let x be the amount she saves each month.

your final answer is x ≥

hope this !

f(x) is going down by 4

step-by-step explanation:

(its either that or its going left by 4)

thats not a system of equations, that is a solution

hello from mrbilldoesmath!

answer:   x^2 + y^2 = 1024

discussion:

the equation of a circle with center (h,k) and radius "r" is

(x-h)^2 + (y-k)^2 = r^2.

in our case

(x-0)^2 + (y-0) ^2 = 32^2 = 1024

you,
