9*12=108
4*x=4x
so, 4x/108
4x=108
x=27
Answer:
y=4x-3
Step-by-step explanation:
Parallel lines will always have the same slope (the number that comes before x in an equation). So, we can plug in 4 to the equation.
y=4x+?
Let's say the ? is b. If we plug in the point (1,1) into y=4x+b, we get
1=4(1)+b
reduce
1=4+b
subtract 4 from both sides
-3=b
and now we can add b=-3 into the original answer, and we get y=4x-3!
The answer is the last one; to express very large or small numbers.
We use it so we can show big or very small numbers in an easier way.
It would be both the penny and the quarter.
The hundredth place would be the third one from the left.

So therefore the quarter and penny both have a five in that spot.
