Answer:
(4,1)
Step-by-step explanation:
Answer:
roots : 4, -4, i, -i
Step-by-step explanation:
This gets a bit tricky.
We have to substitude x^2 as u in this problem.
Now to rewrite x^4 − 15x^2 − 16 = 0 with u, we get
u^2 - 15u - 16 = 0
( u - 16) (u + 1)
U = 16
U = -1
<em>This is not the end of the problem. </em>
Now we have to substitute x^2 back to u.
x^2 = 16 --> we get the roots 4 and -4
x^2 = -1 --> we get the roots i and -i
tadah!
N = no solution
-4 ( 6 - 2n ) = 30 + 8n
-24 + 8n = 30 + 8n
Subtract 8n from both sides
-24 = 30
This is invalid therefore no solution
Answer:
m=11
Step-by-step explanation:
11-2(3m-10)=5(4-m)
11-6m+20=20-5m
11+20=20+m
11=m
Answer:
divide 11 by 1. the answer would be 0.0909
Step-by-step explanation:
if you have a graphing calculator then you have the option to put it in as a fraction and then you would put it into a decimal. and if not then you could do it on paper.
