Answer:
Step-by-step explanation:
Given is a Differential equation as

To bring it to linear form we can divide the full equation by x

This is of the form
y'+p(x) *y = q(x)
p(x) = 1/x
So find

Solution is

Use the initial value as y(e) =1

So solution is

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.

2
Answer:
3.5 miles
Step-by-step explanation:
We need to convert the fraction into decimal and add up both in decimal form and then make our estimate (closest to the exact answer).
1 and 1/8th means 1.SOMETHING
Dividing 1 by 8 would give us:
1/8 = 0.125
Hence, 1 1/8th = 1.125
Total miles = 2.57 + 1.125 = 3.695
THis is closes to 3.5 miles. THis is the answer.
Step-by-step explanation:
x+ 2(7-x) = 11
x+14-2x = 11
-x = -3
x = 3
3+ y = 7
y = 4
x + 2(22-x) = 48
x + 44 -2x = 48
-x = 4
x = -4
-4 + y = 22
y = 26
y = 45-x
x + 2(45-x) = 36
x + 90 -2x = 36
-x = 54
x = -54
-54 + y = 45
y = 99
