Answer:
Step-by-step explanation:
Given the rational expression: 
, to express this in simplified form, we would need to apply the concept of partial fraction.
Step 1: factorise the denominator
Thus, we now have: 
Step 2: Apply the concept of Partial Fraction
Let,
= 
Multiply both sides by (x - 1)(x - 4)
= 
Step 3:
Substituting x = 4 in
Substituting x = 1 in
Step 4: Plug in the values of A and B into the original equation in step 2
<span>The regular octagon has rotational symmetry. Since it is comprised of 8 "equal parts", divide 360º/8 to determine the smallest angle of rotation. 360º/8 = 45º. </span>
Answer:
The common denominator is 100 because they dont have a number lower so 20*5 is 100 and 25*4 gives you 100
Step-by-step explanation:
Answer:
y-9=2(x-3)
Step-by-step explanation:
The point-slope formula is: y-y1=m(x-x1)
y1 and x1 is where you plug in the coordinate and m is the slope.
y1 is the second number of the coordinate (x, y)
So, y1 is 9 in this case
x1 is the first number of the coordinate (x, y)
So x1 is 3 in this case
Do you get it or do I need to explain further?
Given:
A sum of money is divided between A,B and C in the ratio 9:8:7.
Total sum is 480.
To find:
The part of money A get.
Solution:
Let A, B and C get 9x, 8x and 7x respectively.
Total sum is 480.
Divide both sides by 24.
Now,
Therefore, amount received by A is 180.
