Rectangle ABCDABCDA, B, C, D is graphed in the coordinate plane. The following are the vertices of the rectangle: A(-8, -6),A(−8,−6),A, left parenthesis, minus, 8, comma, minus, 6, right parenthesis, comma B(-3,-6)B(−3,−6)B, left parenthesis, minus, 3, comma, minus, 6, right parenthesis, C(-3, -4)C(−3,−4)C, left parenthesis, minus, 3, comma, minus, 4, right parenthesis, and D(-8, -4)D(−8,−4)D, left parenthesis, minus, 8, comma, minus, 4, right parenthesis. Given these coordinates, what is the length of side ABABA, B of this rectangle? units

hello from mrbilldoesmath!

answer:

a(n) - a(n-1) -3

discussion:

this ones a bit interesting. given a(n) = 5 - 3n consider this:

a(n-1) = 5 - 3(n-1)

          = (5 - 3n) + 3             => but a(n) = 5 - 3n, the first term

          = a(n)   + 3                 => subtract 3 from both sides

a(n-1) -3 = a(n)  

or

a(n) - a(n-1) -3

(- 1, 0 )

step-by-step explanation:

an x- intercept is where the function crosses the x- axis.

to find the x- intercept/s look for the value of x when f(x) = 0

from the given table there are 3 values of x where f(x) = 0

when x = - 1, x = 2, x = 3

the one that is listed is (- 1, 0 )
