Use the number line below, where RS = 5y +2, ST = 4y + 7, and RT = 81. a. What is the value of y?
b. Find RS and ST.

i believe it is c.y = 9x

rise over run. 9 units up over 1 unit right or 9/1

answer: list the statements and i will follow up!

step-by-step explanation:

-60.75

step-by-step explanation:

just add the numbers then put the negative sign on it

x coordinate can be written by using the formula, x= x1 + 2/5(x2 - x1)

step-by-step explanation:

formula

x = x1 + p/w(x2 - x1)

let the line segment ab with a(x1,y1) and b(x2,y2)

a point(x,y) divide ab in the ratio, 2: 3 the x coordinate can be written as

x = x1 + p/w(x2 - x1)

here p=2 and w = 2+3

therefore,

x coordinate can be written by using the formula, x= x1 + 2/5(x2 - x1)

similarly y coordinate y = y1 + 2/5(y2 - y1)
