Answer:
The line passes through the points ( 0 , 4 ) and ( 12 , 0 )
Step-by-step explanation:
Given equation of line as :
y = - x + 4
Let the points through which the line passes are
( ,
) , (
,
)
Now, for x = 0 , The line equation is y = - × 0 + 4
I.e for x = 0 , y = 0 + 4 = 4
So, ( ,
) = ( 0 , 4 )
Again , for y = 0 , The line equation is 0 = - × x + 4
I.e for y = 0 , The line equation is 4 =
Or, for y = 0 , x = 4 × 3 = 12
So , ( ,
) = ( 12 , 0 )
Hence The line passes through the points ( 0 , 4 ) and ( 12 , 0 ) Answer
She has 47 total
20 are from Europe
some are from Africa,
and some from Asia
how many from Africa? hmm let's say "a"
how many from Asia? hmm let's say "b"
we know that, she has twice as many "a" as she has "b" stamps,
so, whatever "b" is, a = 2 * b, or a = 2b
so.. let us add them together
solve for "b", to see how many from Asia she has
what's "a"? well, a = 2b , that's how many African ones she has :)
