8.5: Tables and Chairs Andre is setting up rectangular tables for a party. He can fit 6 chairs around a single table.
Andre lines up 10 tables end-to-end and tries to fit 60 chairs around them, but he is surprised
when he cannot fit them all.
1.
Write an equation for the relationship between the number of chairs c and the number
of tables / when:
a.
the tables are apart from each other:
2.

the tables are placed end-to-end:
C00003
3.
4.
Is the first relationship proportional? Explain how you know.
5.
Is the second relationship proportional? Explain how you know.

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.

step-by-step explanation:

the function makes a strait line horizontally with no x intercept but a y intercept at 9.
