Mayflies are a type of aquatic insect that live in freshwater ecosystems and eat aquatic producers called algae. Trout are a type of fish that eat mayflies, and herons are a type of bird that hunt trout. Which distribution of organisms is necessary for this food chain to be sustainable? A. A lot of herons to keep the trout population lower B. Alot of algae and a few herons C. Equal numbers of herons, trout, and mayflies D. More mayflies than algae ​

it happens during combustion and impacts the environment because the plants and trees take in that and it can cause them to die.

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571

step-by-step explanation:

x=-7

step-by-step explanation:

x+3=-10

-10+3=-7

x=-7

alright so i think for this one it would to draw it out. this may be hard for me to try and draw, but i will do my best on here:

        r

  /       |     \

notice how it forms 2 triangles inside one bigger triangle.

so if we know the angle spr is the same as psr that is saying the measure of angle p is the same as angle s. this means the big triangle psr is either isosceles or equilateral. in both cases, the triangle is perfectly symmetrical when split down the middle, which is in this case rq. because we know it is perfectly symmetrical on both sides, we know that the two triangles inside the bigger one are equal.
