Solve each system of equations algebraically y= x-6 y= 2x

Mathematics
1 answer:
lbvjy [14]3 years ago

Answer: x = -6

Step-by-step explanation: The problem gave us the y value, so we can just substitute it into the equation and solve it.

y = x - 6

y = 2x

2x = x - 6 (substitute the y value into the equation)

1x = -6 (subtract x on each side)

x = -6 (1x is basically saying x so you do not need to divide)

Serggg [28]

<u>Answer:</u>

The correct answer option is \frac{25}{9}.

<u>Step-by-step explanation:</u>

We are given the following expression and we are to evaluate it when a = 5 and k = -2:

[\frac{3^2a^{-2}}{3a^{-1}} ]^k

Substituting the given values of  a and k to get:

[\frac{3^2(5)^{-2}}{3(5)^{-1}} ]^{-2}

\frac{3^{(2\times -2)}.5^{(1\times-2)}}{3^{(-1\times-2)}.5^{(2\times-2)}}

\frac{3^{-4}.5^{-2}}{3^{-2}.5^{-4}}

3^{-2}.5^2

\frac { 1 } { 3 ^ 2 } . 2

\frac { 1 } { 9 } . 2 5

\frac { 2 5 } { 9 }
