01:29:30 Which input value produces the same output value for
the two functions on the graph?
x= -1
x = 0
x= 1
x = 2

hello from mrbilldoesmath!

answer:

x - 3

discussion:

x^2 - 9 = (x-3) (x+3)   so

(x^2-9)/ (x + 3) = x-3

you,

i got 10.28 but that rounds up to 10.3

answer: both chords and diameters have two endpoints on a circle. diameters must intersect the center of a circle.

8.75

how-to:

first, we need to find what we have to work with.

since i know that we have 7 (years) and 0.8 (inches), we can use these to solve and find the equation!

secondly, what you want to do, is see that we need to know how much growth out of the 0.8 inches he got in only 1 year, instead of 7 years.

let's try to divide.

7 ÷ 0.8 = 8.75
