This is the concept of algebra, we are required to subtract the complex numbers. Thus;
(5-2i)-1(1+8i)
opening the brackets using the distributive property we get:
5-2i-1-8i
collecting the like terms we get:
5-1-2i-8i
=4-10i
the answer will therefore be:
4-10i
You would first have to convert 5 gallons into ounces. There are 128 ounces in 1 gallon. So 128×5= 640. Now you have 640 ounces. Since Rick is trying to see how many hours it will take to be half full, you divide. So 640÷2=320. Now you have 320 ounces. Now we can find out how many hours it will take by dividing by 5. So 320÷5=64. It will take 64 hours to get Rick's bucket to be half full.
Answer: -7
In the slope-intercept format y = mx+b, b is always the y-intercept. If it is with a positive sign, the y-intercept is positive and if it is negative then the y-intercept is negative.
I believe the answer is three times ^^
