Y = 7x, if x equals the number of hours and y equals the amount of money charged.
Answer:
63+22i
Step-by-step explanation:
(8 - 3i)(6 + 5i)
FOIL
first: 8*6 = 48
outer: 8*5i = 40i
inner: -3i* 6 = -18i
last: -3i*5i = -15 i^2 = -15(-1) = 15
Add together
48+40i -18i +15
Combine like terms
63+22i
I think x=9 so 29 plus 7 is 36. I think it is a 36 degree angle. Correct me if im wrong
