Answer:

Step-by-step explanation:
Let
x ----> the average depth of the resulting layers of ash and rock
we know that
To find out the average depth, divide the cubic kilometers of molten rock by the area where all the ejected material fell.
so

Convert to meters
Remember that

so

Convert to mixed number

Answer:
y = 3x-2
Step-by-step explanation:
We can find the slope using the formula
m = (y2-y1)/(x2-x1)
= (16-4)/(6-2)
=12/4
=3
We then use the point slope form of a line
y-y1= m(x-x1)
y-4 = 3(x-2)
Distribute the 3
y-4= 3x-6
Add 4 to each side
y-4+4 = 3x-6+4
y = 3x-2
This is in slope intercept form

For the 1st one we need to solve x. x-y=2 step1: x-y+y=2+y answer: x=y+2
