Answer:

x = 120

Step-by-step explanation:

10.25x + 680 = 12.5x +410.

Subtract 10.25x from each side

10.25x-10.25x + 680 = 12.5x-10.25x +410.

680 = 2.25x +410

Subtract 410 from each side

680-410 = 2.25x +410-410

270 = 2.25x

Divide each side by 2.25

270/2.25 =2.25x/2.25

120=x

____ [38]

Answer:

y = 5x+3

Step-by-step explanation:

a general line is represented by the equation:

y = mx + n

a line with m=5, that goes through (-1,-2), should satisfy the equation:

-2 = 5×(-1) + n

this is because any point on the line, satisfies it's equation.

from this we get n = 3, hence our answer

Given :-

  • (9^{2} )^{-1/3}

To Find :-

  • To solve the expression .

Solution :-

Given expression to us is ,

(9^{2} )^{-1/3}

We know that ,

9 = 3^2

So our expression becomes ,

\{ (3^2)^2\}^{\frac{-1}{3}}

And , (a^m)^n =a^{mn} . Using this ,

(3^4)^{\frac{-1}{3}}

Again using the same law ,

3^{\frac{-4}{3}}

We know that , a^{-m}=\frac{1}{a^m} . Therefore ,

(3^{-4})^{\frac{1}{3}}

\\\bigg( \dfrac{1}{3^4}\bigg)^{1/3}

\\ \dfrac{1}{\sqrt[3]{3^4}}

Simplify ,

\dfrac{1}{3\sqrt[3]{3}}

This is the simplified expression.
