9(x + 1)^4 - 19(x + 1)^2 + 2 = 0
After expanding and re-factoring, we have:
(3x + 2)(3x + 4)(x^2 + 2x - 1) = 0
solutions are x = -2/3, x = -4/3, x = -1 - sqrt(2), x = sqrt(2) - 1
Answer:
y= 1/2x+2
y int is 2
x int is -2
Step-by-step explanation:
plug in 0 for y int
set the equation equal to 0 for x int
Answer: is an irrational number
Step-by-step explanation:
Like adding three to pi (3.14159265358979323846264....)is still going to be irrational
You would do DRT, distance, rate, time. Rate us what you want. R=T/D- so you would divide 5/6 by 7/10 to get which is 1.1904
with the exception of perfect squares, all square root of whole numbers are irrational, e.g. √5
how about this one:
2.34334333433334.... I am increasing the number of 3s each time, thus
creating a decimal which never ends and never repeats.
or
12.3456789101112131415.... can you see what I am doing?
will it ever end? will it ever repeat?
