Answer:
the feather colors and beak shapes of every bird observed in a park.
Step-by-step explanation:
you said it in your question
Answer:
Key features: the functions can not be parallels, this means that their respective slopes can not be equal or multiple to the other
Step-by-step explanation:
Take for instance 2 linear functions, and
If they intersect in some point in the space, say that is
Then (x1,y1)=(x3,y3), (x2.y2)= (x3,y3)
So, we can compare the two functions and get the following result;
It tells us that if M=m, we get an error, meaning that the functions are in fact parallels and there is no way that they meet in some point.
hope this helps!
X/w=y/5
wy=5x
wy/5=x
w/5=x/y
it should be a
B: 2 and 1/6.
Tricky one if you rush through, its meant to SEEM complicated, like a lot of math questions.
