In order to have a linear equation, you have to write an equation like

The sequence has to start with 3, so we must choose
, because this guarantees that when
we have

Now,
must be even. In fact, if
is even,
will always be even for every possible
, and
will be odd.
So, for example, you might choose

Which will produce the following sequence:

and so on
Answer:
y=2x+105
Step-by-step explanation:
Answer: 6 cups of ketchup per cup of mustard
Step-by-step explanation:
Given : The recipe calls for 3 cups of ketchup for every
cup of mustard.
That means , for
cup of mustard. we need 3 cups of ketchup.
By using proportions, if we multiply 2 on both sides ,we get
for
cup of mustard. we need
cups of ketchup.
⇒ for
cup of mustard. we need
cups of ketchup.
Hence, the required rate = 6 cups of ketchup per cup of mustard
Basically its (9x2)+(2x)=48
to solve for it 18+2x=48
48-18=2x
30=2x
x=15
