Answer:
∫ =
Step-by-step explanation:
To find:
∫
Solution:
Method of substitution:
Let
Differentiate both sides with respect to
[use ]
So,
∫ = ∫ = where is a variable.
(Use ∫ )
Put
∫ =
Use
So,
∫ =
where
Without using substitution:
∫ = ∫ =
So, same answer is obtained in both the cases.
3 2/3 x # = 2/9
# = 2/9 \ 3 2/3
# = 2/33 or 0.067
Answer:

x − y = −
2
Step-by-step explanation:
To write a linear equation in standard form, move each variable term to the left side of the equation and simplify. This is the formula that you want:
A
x + By = C
Since x is on the right side of the equation, switch the sides so it is on the left side of the equation. Switch the equation around.
5
x + 2 = y
Move y to the left side of the equation because it contains a variable. Subtract y from both sides or use what's called Subtraction property of equality.
5
x + 2 − y = 0
Move 2 to the right side of the equation because it does not contain a variable. Subtract 2 from both sides or use what's called Subtraction property of equality.
5
x − y = −
2
As you can see this version of the equation looks a lot like the formula you want meaning this is correct.
Ax + By = C Replace values ===> 5x - y = −

The value of A is RM 205.
Since Billy gave money to a charity over a 20 year period, from Year 1 to Year 20 inclusive, and he gave RM150 in Year 1, RM160 in Year 2, RM170 in year 3, and so on, and Kevin also gave money to the charity over the same 20 years period, but he gave RMA im Year 1 and the amount of money he gave each year increased, forming an arithmetic sequence with common difference RM30, and the total amount of money that Kevin gave over 20 years period was twice the total amount of money that Billy gave, to calculate the value of A the following calculation must be performed:
- Billy = (150 x 20) + 10 + 20 + 30 + 40 + 50 + 60 + 70 + 80 + 90 + 100 + 110 + 120 + 130 + 140 + 150 + 160 + 170 + 180 + 190
- Billy = (150 x 20) + 1900
- Billy = 3000 + 1900
- Billy = 4900
- Kevin = (9800 - (30 + 60 + 90 + 120 + 150 + 180 + 210 + 240 + 270 + 300 + 330 + 360 + 390 + 420 + 450 + 480 + 510 + 540 + 570)) / 20
- Kevin = (9800 - 5700) / 20
- Kevin = 4100/20
- Kevin = 205
Therefore, the value of A is RM 205.
