To determine how many oil changes you will need the first year, you can calculate the number of miles driven the first year and then use that to determine how many groups of 3000 miles you will drive after the first 5000 miles.
1. 52 x 250 = 13000 miles
2. 13000 miles - 5000 miles (1 oil change) = 8000 miles
3. 8000 miles - 3000 miles (1 oil change) - 3000 miles (1 oil change) = 2000 miles
The first year, you will need 3 oil changes.
The last one , because I will now solve it for you and prove therefore.
x²–4x+5=0;
D=(–4)²–4•5=16–20= –4= (2i)².
So:
x1= (4–2i)/2= 2–i
x2= (4+2i)2= 2+i.
This is the whole answer....
Three other u will solve by yourself and have roots which will not be suitable.
Answer:
<u>[x] ≥ x</u>
Step-by-step explanation:
- The absolute value of a number is greater than or equal to itself
- Therefore, the correct answer is :
- ⇒ <u>[x] ≥ x</u>
Answer:
B and C
Step-by-step explanation:
Basically the answer is H + 30% of H.
30% can be written as 0.30, 3/10 or 30/100 for example.
B and C are the equivalent of H + 30% or H.
Answer:
z = -166
Step-by-step explanation:
1. Subtract 3 from both sides to get z/2 = -83
2. Multiply 2 by both sides to get z = -166
z = -166
