Answer:

x = -18, y = 14

Step-by-step explanation:

4x + 6y = 12

x + 2y = 10

Divide both sides of the first equation by 2. Write the second equation below it.

2x + 3y = 6

x + 2y = 10

Rewrite the first equation. Multiply both sides of the second equation by -2 and write below it. Then add the equations eliminating x.

      2x + 3y = 6

(+)  -2x - 4y = -20

-------------------------

             -y = -14

y = 14

Substitute 14 for y in the second equation and solve for x.

x + 2y = 10

x + 2(14) = 10

x + 28 = 10

x = -18

Solution: x = -18, y = 14

Find a formula for the inverse of the function: f(x) = 9–6/x^2, x&gt;0.<br><br><br> f^-1(x)=
QveST [7]

9514 1404 393

Answer:

  f^-1(x) = √(6/(9 -x))

Step-by-step explanation:

The inverse function is the solution to ...

  x = f(y)

  x = 9 -6/y^2

  x +6/y^2 = 9 . . . . . add 6/y^2

  6/y^2 = 9 -x . . . . . subtract x

  6/(9 -x) = y^2 . . . . . multiply by y^2/(9 -x)

  y = √(6/(9 -x)) . . . . take the square root

Then the inverse function can be written as ...

  f^-1(x) = √(6/(9 -x)) . . . . . . x < 9

Can someone please explain what solving in scientific notation is?
nikitadnepr [17]

Step-by-step explanation:

Scientific notation is a way of expressing numbers that are too big or too small to be conveniently written in decimal form.

For example, instead of writing 0.0000000056, we write 5.6 x, 10^-9
