If x = a + bi and y = –a – bi, x + y = 0

1 answer:

7 0

That would be the inverse property of addition. When you add the opposite of a number to that number, your sum will be zero. -a is the opposite of a and -bi is the opposite of bi. When you add x + y (aka the opposites) your total is absolutely nothing!

Hi.

To formally answer your question:

D. y = 0.75x + 11

We can prove this by substituting x with 1 (the initial measurement)

y = 0.75(1) + 11 = 11.75

Mr. blue's first year salary is $30,000 and it doubles each year. what is the explicit rule for the sequence in simplified form?

trasher [3.6K]

Answer: Explicit Rule: a_n=30,000 • 2^n-1

Recursive Rule: a_n = 2a_n-1; a_1 = 30,000

Step-by-step explanation: the explicit rule for a geometric sequence is a_n = a_1 • r^n-1 and the recursive rule is a_n= r • a_n -1.
a_1 is the first term of the sequence, which is this case is 30,000. R is the common ration, which is 2 since it doubles each time. Substitute those numbers into the formulas and that’s what you’ll get. Hope this helps. God bless you!!!

Which expression is equivalent to (-4y-x)-(y-9x) ?

777dan777 [17]

Answer:

-5y + 8x

Step-by-step explanation:

$(-4y-x)-(y-9x)\\\\-4y-x-(y-9x)\\\\\rightarrow-(y-9x)*-1=-y+9x\\\\-4y-x-y+9x\\\\-4y-y+9x-x\\\\\boxed{-5y+8x}$
