Answer:
r = 11/2
Step-by-step explanation:
m = slope
slope, m = (y2 - y1)/(x2 - x1)
-4 = (7 - 9)/(r - 5)
cross multiply
-4(r - 5) = 7 - 9
clearing brackets
-4r + 20 = -2
-4r = -22
r = 22/4 = 11/2
Here is my solution to this question worked out on paper:
Answer:
658.91$
Step-by-step explanation:
Find the total cost
flight cost 397$
staying at the hotel for 6 night cost 6 x 28.43£
= 170.58£ = 233.69$
breakfast for 4 morning cost 4 x 5.15£= 20.6£
= 28.22$
Total cost is 397$+233.69$+28.22=658.91$
Answer: (10 - 6i)/5
(x + yi) + (4(x + yi) + 6i) = 10
⇔ 5(x + yi) + 6i = 10
⇔ 5(x + yi) = 10 - 6i
⇔ x + yi = (10 - 6i)/5
