Answer:

<BDC and

<CDB but be sure and read what is below.

Step-by-step explanation:

The trick is to put the letter for the angle in the middle of its 3 letter name.

<BDC is the same thing as <CDB

You have named it in 2 different ways. The letters on either end don't matter as much as having D in the middle.

Find the inverse function (find f^-1)

Reil [10]

Step-by-step explanation:

f(x) = (x-2)/(3x+3). Let y = f(x).

Then y = (x-2)/(3x+3).

y(3x+3) = x - 2

3xy + 3y = x - 2

3xy - x = -3y - 2

x(3y-1) = -(3y+2)

x = -(3y+2)/(3y-1)

Hence, the inverse of f(x) is -(3x+2)/(3x-1).

If x+y=10 and x-y =6 what is the answer of x cube - y cube fast

AfilCa [17]

Answer:

x+y=10 which means that x=10-y

Replace 10-y in the other equation which gives you:

10-y-y=6

10-2y=6

-2y=-4

y=2

Replace 2 in any of the 2 equations same answer for both:

x+y=10

x+2=10

x=8

So,

${x}^{3} - y^{3}$

$= {8}^{3} - {2}^{3}$

=512-8

=504

Hope this helps!
