Answer:
x=1,
y=1/2
Step-by-step explanation:
4x-8y=0
so 4x=8y
x=2y
5x+2y=6
because x=2y
so:
5x+x=6
6x=6
x=1;
then
x=2y
1=2y
y=1/2
Answer:
8. y=2x+6
9. y=1/2x-5
Step-by-step explanation:
Use point slope form to figure out the y intercept. Because it needs to be parallel, the same slope will be used to solve for point slope form.
It looks like it should be the first one and the third one

Everything inside of the parenthesis needs to be to the 4th root. So you can see it as:
3^4 * (b^3)^4
3^4 = 3*3*3*3 = 81
And using rules of exponents, you need to multiply those exponents.
b ^ (3*4) = b^12
Put them together... 81 b^12
