Solve y^4/5=34
Svetradugi [14.3K]

Answer:

The best choice is y = 82.1

Step-by-step explanation:

Just simplify both sides of the equation, then isolate the variable.

Which makes it's exact form y= 34^5/4 and when converting it to decimal form it becomes y = 82.1

F(x)=7x-17/x^2+6x+9 <br>solve using fractional decomposition
Kazeer [188]

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

I am Lyosha [343]
Plug in (3,-1) into equations to see:
-1=2-3
-1=-1 CHECK

3-2(-1)=2(3)
3+2=6
5=6 NO

This is not a solution.
