− 2 ± 2 i √ 2 I think that’s the answer
Answer:
-a +6=b
Step-by-step explanation:
a= 6-b
a-6= -b
a- 6/-1 = -1b/-1
-a+6 =b
First, let's call "a number": n
Then. "eight less than a number" can be written as: n-8
This expression "is no more than 14" can be written as: n−8≤14
[13,22]
Goal: Try to get the variable by itself!
5n+4=-26
-4= -4
5n=-30
n=-6
Answer:
3k^2 -k+5
reason:
when adding two equations together, you combine like terms.
First, add -2 to 7 to get 5
Then, add k, or 1k, to -2k, which gives you -1k, or just -k
3k^2 stays the same because there are no like terms in the other equation to combine it with
