Answer:
f(x) = 7/(x+3) -38/(x+3)²
Step-by-step explanation:
The denominator is a perfect square, so the decomposition to fractions will involve both a linear denominator and a quadratic denominator.
You can start with the form ...
... f(x) = B/(x+3) + A/(x+3)²
and write this sum as ...
... f(x) = (Bx +3B +A)/(x+3)²
Equating coefficients gives ...
... Bx = 7x . . . . . B = 7
... 3B +A = -17 . . . . the constant term
... 21 +A = -17 . . . . filling in the value of B
... A = -38 . . . . . . . subtract 21 to find A
Now, we know ...
... f(x) = 7/(x+3) -38/(x+3)²
Answer:
It's table D
Step-by-step explanation:
I just took the test.
The interest rate offered would decrease. The federal reserve sets the rates to help prevent inflation, deflation etc
Hey there!
-1 ¼ • 9
= - (4+1)/4 • 9
= -5/4 • 9
= -(5 × 9)/4
= <u>-</u><u> </u><u>4</u><u>5/4</u>
= <u>- 11.25</u>
Hope it helps ya!
