The third graph, with (-4,0),(-3,1),(-2,-3),(-1,-2), (1,2),(2,3),(3,-1),(4,0)
We see the pattern, if we have (x,f(x)) we have (-x, -f(x)). In other words
f(-x) = -f(x)
which is the definition of an odd function.
14-x=9
14=x+9
x=14-9
x=5
14+5=19
x+y=19
x-y=(-5)
Adding both equations,
We get,
2x=14
x=7
7+y=19
y=12
36 bowls - since with one gallon he can eat 12 bowls (as demonstrated by 1/12), you multiply 12 by 3 to get 36 bowls.
I'm here buddy,
so, let's take the value of the two bags with equal weight as x.
= x + x + (x + ) =
= 3x + =
= 3x = -
( let's take the LCM of 4 and 5 = 20
= 3x =
= x = ÷ = × =
So, the weight of the equal bags are and the weight of the third bag ( heavy one ) is + = + =
1st bag = kg
2nd bag = kg
3rd bag = kg
Hope it helps...
