Step-by-step explanation:
It should be zero because the y intercept is 0
3 1/2. Hope that this helps as I’m not sure what the question is asking for
X + Y = 18
X=chickens, Y=Cows
2x + 4y = 60
Let's try 8 and 10.
16 + 40=56, no, 32+20=52, no. 8&10 do not work.
Let's try 9 and 9.
18+36=54, no. 9&9 do not work.
Let's try 11 & 7.
22+28=50, no. 14+44=58, no.
Let's try 12 & 6.
24+24=48, no. 12+48=60 YES!
There are 12 cows and 6 chickens.
Answer:
C
Step-by-step explanation:
This is a linear equation in one variable and has 1 solution
12x + 6 = 5x ( subtract 5x from both sides )
7x + 6 = 0 ( subtract 6 from both sides )
7x = - 6 ( divide both sides by 7 )
x = - 
← 1 solution
