Is 4x^2+y=8 a linear equation

No, linear function graphs always have the x raised to the first power

0.1 repeating, or 1/9

Step-by-step explanation:

To solve, you have to first leave the 3, then add up the exponents,

4 - 6 = -2.

Then -2 becomes the exponent, so 3^-2.

When simplified to a number, it is

0.1 repeating, or 1/9.
