Answer: don't know sorry
Step-by-step explanation:
Answer: the first one -2+5i
Step-by-step explanation: because if we just take out the parenthesis the we can do it like a regular equation so 6-8 is -2 and 2i - -3i the 2 negatives gives us a positive so we get 2i+3i and get 5i so the equation would be -2+5i
Answer:
3x + 100 < 2x - 250
Step-by-step explanation:
The problem said that Keisha's guess was "250 less than twice the number".
It was written as 250-2x, which is actually twice the number less than 250, because we are subtracting 2x. We just need to write it like this:
2x-250
So the inequality should be:
3x + 100 < 2x - 250
Perimeter of a triangle =sum of all sides
=2x-7+5x-3+2x-2
=2x+5x+2x-7-3-2
=9x-12
Answer:
Step-by-step explanation:
Since g(f(x))=x g ( f ( x ) ) = x , f−1(x)=3√x+8 f - 1 ( x ) = x 3 + 8 is the inverse of f(x)=(x−8)3 f ( x ) = ( x - 8 ) 3 .
