Mo's Cafe has 12 tables. Some tables can sit 2 people while others
can sit 4 people. How many of each
type of table does the cafe have so
that exactly 38 customers can be
seated.

    A = 5

                  B = 7

Step-by-step explanation:

Let A be number of 2 seat tables

Let B be number of 4 seat tables

  A + B = 12

  A = 12 - B

        2A + 4B = 38

2(12 - B) + 4B = 38

24 - 2B + 4B = 38

                2B = 14

                  B = 7

  A = 12 - 7

  A = 5

its mainly because the pattern will be infinite and will never end. it will look like a gilder or like a filpbook when set to motion.

step-by-step explanation:

substitution for (0,1)

y=x^2+4x+1

1=0^2+4(x)0+1

1=0+4(x)0+1

1=4(x)0+1

1=0+1

1=1

substitution for (-3,-2)

y=x+1

-2=-3+1

-2=-2
