Perpendicular is slope multiplies to -1
for
ax+by=c
slope=-a/b
4x-3y=6
-a/b=-4/-3=4/3
perpendicular to 4/3 is -3/4
point slope form
y-y1=m(x-x1)
for slope=m
a point is (x1,y1)
point (4,-2)
slope is -3/4
y-(-2)=-3/4(x-4)
y+2=-3/4(x-4)
or converted
y=-3/4x+1
or
3x+4y=4
You would do 48-20=28 points the pioneers scored
Answer:
39
Step-by-step explanation:
The biotic factors of an ecosystem are arranged in feeding levels known as trophic levels.
<h3>What is a
trophic level?</h3>
The trophic level of an organism is the position it occupies in a food web. The trophic level of an organism is the number of steps it is from the start of the chain.
Below are the list of the trophic levels:
- 1st Trophic Level (Producer) : Makes its own food
- 2nd Trophic Level (Primary Consumer): Consumes producers
- 3rd Trophic Level (Secondary Consumer): Consumes primary consumers
- 4th Trophic Level (Tertiary Consumer): Consumes secondary consumers
The biotic factors of an ecosystem are arranged in feeding levels known as trophic levels.
