Answer:
The change in elevation is 20,744 ft
Step-by-step explanation:
Let
x -----> the lowest elevation in a region
y -----> the highest elevation in a region
we have that
x=-264 ft
y=+20,480 ft
We know that
To find out the change in elevation from the lowest elevation to the highest elevation, subtract the lowest elevation from the highest elevation (or find the difference in absolute value)
so
y-x
substitute the values
5,345.6106 is the answer! BYE:)
-x+2 > 1
-x+2+x > 1+x .... add x to both sides
2 > 1+x
x+1 < 2
x+1-1 < 2-1 ... subtract 1 from both sides
x < 1
After solving for x, we get x < 1
To graph this, plot an open circle at 1 on the number line and shade to the left of this value. The open circle indicates that 1 is not part of the solution set.
If your teacher requires you to graph this on an xy grid, then draw a vertical line through 1 on the x axis. Make this vertical line a dashed line. Then shade the entire region to the left of this dashed line. Any point in this shaded region will have an x coordinate that is less than 1. The dashed line acts like the open circle. The dashed line tells the reader "any point on this dashed line is not part of the solution set"
