Answer:

9^{-7}, 9^{-2}

Step-by-step explanation:

\frac{9^5\times9^{-9}}{9^3}\\\frac{9^{-4}}{9^3}\\ 9^{-7}

When you multiply like terms, you add their powers. When dividing like terms, you subtract their powers (subtract the power in the denominator from the one in the numerator).

(9^4)^3\times9^{-14}\\9^{12}\times9^{-14}\\9^{-2}

it confuses me when i have to fill in the in between i just dont quite understand how to work it out please explain it clearly
prisoha [69]

<em>Make the unknown numerator be x and unkown denominotor be y</em>

<em>We have :  7 - </em>\frac{x}{y} = 6\frac{4}{5}

            =>       \frac{x}{y} = 7 - 6\frac{4}{5}

                       \frac{x}{y} = \frac{1}{5}

<em>So we need to fill in the box :</em> \frac{1}{5}

<em>If the answer is helpful, Brainliest please!</em>

Solve the equation 4x^2 + 24x + 13 = 2x^2+ 6x to the nearest tenth.
Licemer1 [7]

Answer:

-0.8 and -8.2

Step-by-step explanation:

To solve a quadratic you first need to have one side of the equation equal to zero (because x-intercepts are when y is zero).

4x^2 + 24x + 13 = 2x^2 + 6x

2x^2 + 18x + 13 = 0

Then you can use the quadratic formula to solve for x. You will then come to

-18 ± sqrt(220) / 4

This will simplify out (rounding to the nearest tenth) to -0.8 and -8.2
