Step-by-step explanation:

$( {4}^{ - 3} ) ^{ - 3} = {4}^{9}$

$( { - 4}^{9} ) ^{2} = ( - 4) {}^{18}$

$( {4}^{6} ) ^{ - 3} = \frac{1}{{4}^{18}}$

$( { - 4}^{9} ) {}^{2} = ( { - 4})^{18}$

$({4}^{0} ) = {4}^{0}$

Hope this is correct and helpful

Which could be the first step in solving this system of equations by substitution?

Ainat [17]

Answer:

The first step is to replace the y in y-x=15 with 7x (we can do this because the first equation tells us that they're equal)

solve and get

(2.5,17.5)

or x= 2.5 y=17.5

Step-by-step explanation:

The first step is to recognize that y=7x which means that we can just replace the y in the second equation with 7x

7x-x=15

6x=15

x=2.5

Then we can solve for y

y=7(2.5)

y=17.5
