Answer:
Step-by-step explanation:
8x = 12^8
x = 12*8/8
= 53747712.
Answer:
y=x+8 because your friend's allowance is y but also $8 more than yours, x. x+8 is her allowance so x+8=y
<u><em>Answer</em></u>

<u><em>Explanation</em></u>
Based on the given conditions, formulate:: 
Substitute
into
:: 
Rearrange variables to the left side of the equation: 
Calculate the sum or difference: 
Divide both sides of the equation by the coefficient of variable: 
Cross out the common factor: 
Answer:
y=-4x+2
Step-by-step explanation:
slope intercept form: y=mx+b
parallel lines have the same slope (-4 in this case)
plug in the point (0,2) to the new equation y=-4x+b
2=-4(0)+b --> b=2
final answer: y=-4x+2
