Answer:
x=-1
Step-by-step explanation:
x3+x2=-9x-9
add 9x +9 on each side
x^3+x^2+9x+9=-9x-9+9x+9
x^3+x^2+9x+9=0
factor out an x^2 from the left 2 terms and a 9 from the right 2 terms
x^2 (x+1) +9(x+1) = 0
factor out x+1
(x+1) (x^2+9) = 0
using the zero product property
x+1 =0 x^+9 =0
x=-1 x^2 =-9
x=-1 sqrt(x^2) = sqrt(-9)
x=-1 x = ±3i
Answer:
Step-by-step explanation:
The answers are given in slope-intercept form.
The slope (m) in the question is -3. The y-intercept (b) is 8.
Plug the values in you get:
Hope this helps.
-6x+3=45
-3 -3 subtract
-6x=45
Divide both sides by -6
X=-7
I think this is the answer
Answer:
(a) Is not possible
(b) It is possible
(c) It is possible
(d) Is NOT possible.
Step-by-step explanation:
(a)
Is not possible, notice that for any function such that
you would have that
And for, lets say -3,3 you have that
therefore is not possible to find a function that is one to one.
(b)
It is possible. Take the following function
since is periodic it will take positive and negative numbers and if you multiply by each period will become bigger and bigger.
(c)
It is possible. Take the function
Then
and is one to one.
(d)
It is NOT possible because and that will always be positive.
