Answer:
5 cows and 3 ducks
okay well there are 8 heads and each animal has a head meaning that there are a total of 8 organisms in total. Cows have 4 legs and ducks have 2. Lets say that c is cows and d is ducks. You would have the equations ...
c+d=8
4c+2d=26
well d techniacally = 8-c, so plug in (8-c) for the value of d
4c+2(8-c)=26. Distribute to get
4c+16-2c
and then add like terms. Soy ou would get
2c+16=26.
then just isolate the variable but subtracting 16 from both sides and dividing 2 on both sides. The answer you would get is that c=5 so there are 5 cows. Plug in 5 for c so you get 5+d=8 and tadaaaa you subtract 5 from both sides to get that there are 3 ducks.
hope this helps :)

Step-by-step explanation:
In this question, we have to find the graph that fits the inequality.
First, we need to simplify the inequality.
Solve:
d - 4 > -3
Add 4 to both sides.
d > 1
Now, we can find which graph fits the inequality.
We know that the graph has to start at 1, so we can already eliminate answer choices A, B, and D.
General rule of them is that the direction of the arrow is the opposite direction of the inequality sign.
If the inequality is ">", the arrow on the graph should be pointed rightward (→)
If the inequality is "<", the arrow on the graph should be pointed leftward (←)
Since out inequality sign is ">", the arrow has to be pointing rightward, therefore making answer choice "C" the right answer.
Answer: why?
Step-by-step explanation:
A point of concurrency is a place where three or more, but at least three lines, rays, segments or planes intersect in one spot. If they do, then those lines are considered concurrent, or the the rays are considered concurrent. Hope it helps!
