After college graduation, Mario received employment offers from two companies. The first company offered a yearly salary of $31,
Alexandra [31]
The first thing we must do for this case is to define a variable:
 x: number of years
 y: total salary
 We have then:
 For first company:
 y = 1500x + 31000
 For second company:
 y = 2000x + 28500
 Equaling both equations we have:
 1500x + 31000 = 2000x + 28500
 Clearing x:
 2000x - 1500x = 31000 - 28500
 500x = 2500
 x = 2500/500
 x = 5
 Answer:
 
It will take for the salaries to be the same about:
 
x = 5 years

Alisha is drawing a map of her school. She is not able to draw the map to scale because it would be too large. Each centimeter o
arsen [322]

Here we want to see which one of the given graphs is the one with the correct relationship between distance in centimeters and meters. We will see that the correct option is the first graph.

<h3>Working with changes of scale.</h3>

So we know that each centimeter on the map must represent 4 meters in reality, this is a change of scale, so the scale is:

1cm = 4m

First, this relation is linear (each centimeter will always be equal to 4 meters) so the two bottom options that are not linear can be discarded, so we only have the first and second graph.

If you read them, you can see that in the second one 1 meter is equivalent to something near 5 cm, so this is also incorrect.

The only graph that shows a correct scale is the first one, where for each increment of 1 unit on the horizontal axis (the one in centimeters) we have an increase of 4 m (estimated). This means that 1cm = 4m, as in our change of scale.

So the correct option is the first graph.
