8) x represents the number of pounds of peanuts, and y represents the number of pounds of raisins
9)
Solve:
x+2y=9
-2y -2y
x=9-2y
2(9-2y) + 3y=14
18-4y+3y=14
-18 -18
-y=-4
y=4
x+2(4)=9
x+8=9
x=1
There are three answers and they are: choice 2, choice 3, choice 5
======================================================
Further Explanation:
Choice 1 is false because the intersection of the altitudes of a triangle leads to the orthocenter.
----
Choice 2 is true because the three medians of any triangle always intersect at the centroid. A median is a line that goes from one vertex to the midpoint of the opposite side. In this case, we go from point E to the midpoint of side CD. The midpoint of CD is found by bisecting segment CD (see choice 5)
----
Choice 3 is true. This is effectively the same as choice 5 below. The "perpendicular" aspect does not matter.
----
Choice 4 is false. Following the steps mentioned here will create an altitude line (see choice 1)
----
Choice 5 is true. To bisect something is to cut it in half. Let's say that point F is the midpoint of line segment CD. This means that line segment EF is one of the three medians of triangle CDE.

edit update: I changed choice 3 from false to true

Answer:
The current population (in 2005) is 4000 because it is the constant. The slope tells us how many people are added to the population, so 70 per year. For ex. 2008 (2008- 2005 = 3=> 3 x 70 = 210 => 210 + 4000 = 4210).
