The slope of AC is -0.4
Proof:
In triangles ABC and DBE,
∠DBE is common to both triangles.
AB = 2DB (D is the midpoint of the interval AB)
Also, BC = 2BE (E is the midpoint of the interval BC)
Thus triangles ABC and DBE are similar in the ratio 2:1
Since, they are similar, ∠BDE must equal ∠BAC (corresponding angles in similar triangles)
If ∠BDE = ∠BAC, DE must be parallel to AC (corresponding angles are equal along parallel lines)
Thus, the slope of AC = the slope of DE
Thus, the slope of AC is -0.4
Answer:
<h2>C. 8 + 3i</h2>
Step-by-step explanation:
(9 + 6i) - (1 + 3i) = 9 + 6i - 1 - 3i = (9 - 1) + (6i - 3i) = 8 + 3i

When the insurance company want a plan with a deductible of $4,000, they need to charge a minimum of $18000 for premiums.
<h3>What is a deductible?</h3>
It should be noted that a deductible simply means the amount of money that is paid out of the pocket of the policy holder.
From the information given, each accident costs $18,000 on average. Therefore, this is the minimum amount of premium.
When they want a plan with a premium of $1,000, the amount that they'll need to charge for deductibles will be:
= (4000/18000) × 1000
= $220
