Answer:
The answer is A and E
x2+(y−3)2=36
x^{2}+(y+8)^{2}=36x2+(y+8)2=36
Set the number of chickens as x and number of cows as <span>y
</span>so the farmer has total 28 animals
so x+y=28
you know that since the animals are healthy
chickens will have 2 legs and
cows will have 4 legs
the total number of legs are 64
so 2x+4y=64
since you want to find the number of cows
so from the first equation <span>x+y=28
</span>we will get another equation <span>x=28-y
</span>then plug into <span>2x+4y=64
2(28-y)+4y=64
56-2y+4y=64
56+2y=64
-56 -56
2y=8
y=4
</span>
Answer:
y < 4 would be the solved inequality I believe
Step-by-step explanation:
y + 4 < 8
- 4. - 4
y < 4
