Use the graph to answer the questions.
At what elevation did Julio begin?
At what elevation did Kathy begin?
Elevation (miles)
Who made it to 8 miles first?
Who experienced a greater elevation change?
The hours)

Step-by-step explanation:

The elevation at which each started is where their respective graphs go through the y axis.  Julio's graph goes through the y axis at 4 miles and Kathy's goes through at 0 miles, or in other words, on the ground.

As far as who made it to 8 miles first.  Locate the 8 on the y-axis and go straight across, following that horizontal line y = 8.  The first graph you run into on that horizontal line is Kathy's.  Where her graph meets y = 8, drop straight down to the x-axis and see that she hit 8 miles at a little over 16 hours.  Julio hit 8 miles at 18 hours.  

As far as who experienced a greater elevation change...that was Kathy.  She started at ground level and climbed to 9 miles, while Julio started at 4 miles and climbed to 9 miles.

x= -3

step-by-step explanation:

step 1: simplify brackets

4 - x - 1 = 6

step 2: simpilfy

3 - x = 6

step 3: subtract 3 from both sides

-x = 6 - 3

step 4: simpilfy 6 - 3

-x = 3

step 5: multiply both sides by -1

x = -3

step-by-step explanation:

consider an orange peel: if you want to try and lay it flat, you have to stretch it, we know exactly how things are being stretched or squashed at any given point. we have many different map projections because each has different patterns of some projections can even preserve certain features of the earth without
