Answer:
y=2x
Step-by-step explanation:
2 up, 1 over. put rise over run so that concludes the 2x.
The line starts at 0 so there is no y-intercept
Its 14 (20 chars limit thing)
Answer:
x = 
, y = 6
Step-by-step explanation:
5x + y = 7 → (1)
20x + 2 = y → (2)
Substitute y = 20x + 2 into (1)
5x + 20x + 2 = 7
25x + 2 = 7 ( subtract 2 from both sides )
25x = 5 ( divide both sides by 25 )
x = 
=
Substitute this value into (2) and evaluate
20( ) + 2 = y
4 + 2 = y , so
y = 6
Answer:0 = 3x - 21
Step-by-step explanation:
From this given function we can take an
x
common from its expression
i.e
x
2
−
6
x
=
x
(
x
−
6
)
As we know that the product of two numbers is zero,when either one of them is zero
then in the above expression that we just factorised
the function can be zero when either
x
=
0
or when
x
=
6
i.e when
x
=
0
,
0
(
0
−
6
)
=
0
when
x
=
6
,
6
(
6
−
6
)
=
6
(
0
)
Finally, our prize of all that math, the zeroes of the function are
0
and
6
these numbers are called the zeroes of the function because when you put these values in
x
the function gives zero.
