( (r+2) * (2r-9)-(r^2+17r+30) )/(r+2)
none of the parenthetical operations or power operations can be simplified further, so multiplication and division first, left to right:
(2r(r+2) -9(r+2) - r^2 + 17r +30)/(r+2)
(2r^2 + 2r -9r+18 -r^2 +17r +30 )/(r+2)
(r^2 +10r +48)/(r+2)
Answer: y = 
x + 8
Step-by-step explanation:
This is asking us to remove the parameter. In other words, we want an equation with only the relation between x and y, so we need to remove the t. There are a few ways to do this, but I am going to set one equation equal to t and then plug it into the next one.
Given:
x = 5t
Divide both sides of the equation by 5:
t = x
-
Given:
y = t + 8
Plug in:
y = (x) + 8
Answer:
y = x + 8
Answer:
y=250x+2000
Step-by-step explanation:
The farmer starts with 2000 trees and adds 250 each year.
Year 0 2000
Year 1 2000 + 250 = 2000+ 1(250)
Year 2 2000 + 250 +250 = 2000 + 2(250)
Year 3 2000 + 250 + 250 + 250 = 2000 + 3(250)
Year 4 2000 + 250 + 250 + 250 + 250 = 2000 + 4 (250)
.....
Year X 2000 + 250x
