Hi!

<u>Given these two equations:</u>

x = y + 8

x + 4 = 2(y + 4)

We want to solve using the substitution method. Knowing that x is equal to y + 8, we can simply plug in 'y + 8' in for x in the second equation, like so:

(y+8)+4=2(y+4)

Combine like terms on both sides:

y+12=2y+8

Subtract y from both sides:

12=y+8

Subtract 8 from both sides:

y=4

Now, we can simply plug the y value in to the first equation, and solve for x:

x=4+8

Simplify:

x=12

<h3>Therefore, x is equal to 12 and y is equal to 4.</h3>

Write:<br> 3^-4 in standard form
pav-90 [236]

Answer:

\frac{1}{81}

Step-by-step explanation:

<u>Key skills: Exponents + Fractions</u>

Use the negative exponent property. If your number is x^-y then it would be the same as 1/x^y

3^-4 is the same as \frac{1}{3^{4}}

3^4 is 81, so your answer would be 1/81.

Hope you have a nice day and understood this!
