X+4y=30 system by substitution <br><br> X-2y=0

Dmitry [639]

Answer:

x=10, y=5

Step-by-step explanation:

For substitution, you always want to get the variable alone. The second equation (x-2y=0) will be easier to substitute into the first equation.

x-2y=0

x=2y

You can substitute 2y as x on the first equation (x+4y=30).

2y+4y=30

6y=30

y=5

Plug y=5 into any equation.

x+4(5)=30

x+20=30

x=10

lyudmila [28]

Answer:

(B) $\dfrac{1}{m^8}$

StartFraction 1 Over m Superscript 8 EndFraction

Step-by-step explanation:

We want to find the simplified form of: $m^{-8}p^0$

$m^{-8}p^0=m^{-8}$ X p^0\\p^0=1\\m^{-8}=\frac{1}{m^8} \\$Therefore:\\m^{-8}$ X p^0=\dfrac{1}{m^8} X 1\\=\dfrac{1}{m^8}$

The correct option is B.
