**y=-2x+1**

**So, -2x, you go down 2 every time you go across 1. So, the rise is -2, and the run is 1, so it's -2x**

**+1: when you reach an x of 0, you are still up 1. So, the y-intercept is 1**

**Answer:**

x = 9

**Step-by-step explanation:**

Given a segment joining the midpoints of 2 sides of a triangle, then

the segment is half the length of the 3rd side , that is

3x = 0.5 × 54 = 27 ( divide both sides by 3 )

x = 9

Hi there! Okay, so the bases are 60 feet apart. From home base to first plate, you would travel 60 feet and from first plate to second plate, you travel another 60 feet. 60 + 60 is 120. Home plate is 120 feet away from second base.

**Answer:**

Length=18 Width=6

**Step-by-step explanation:**

Hello, You should first you algebra and and assign the dimensions with letters.

Length=x Width= 1/3x

as its the perimeter you add all the side together

x + x + 1/3x + 1/3x

which equals= 8/3x (this is an improper fraction at the moment)

then we know the total perimeter =48

so 48=8/3 x

so rearrange to get X by it's self

so 48 x 3/8

which x=18

Answer:

1.When manure or commercial fertilizers enter surface water, the nutrients they release stimulate microorganism growth. Without sufficient dissolved oxygen in surface water, fish and other aquatic species suffocate. The resulting dead fish and other aquatic species degrade the water quality and cause unpleasant odors.

2.Eutrophication is a significant increase of algae (microscopic organisms similar to plants) due to the greater availability of one or more growth factors necessary for photosynthesis, such as sunlight, carbon dioxide and nutrients (nitrogen and phosphorus)
