Answer:
840,000,0
Step-by-step explanation:
Her salary 4 years ago would have been $30,000.
If 45,000 is 15,000 less than double her previous salary, we must first add 15,000 to 45,000 to find what double her salary was.
45,000+15,000=60,000.
Since this is twice her salary, we divide this by 2.
60,000/2= 30,000.
So, her salary 4 years ago would have been $30,000.
I hope this helps!
The Tampa Tribune expecting to add 700 new pictures per year to their database in 2041
<h3>The linear equation of the graph</h3>
The equation of the line of best fit is given as:

When the number of pictures added is 700, we have:
y = 700
Substitute 700 for y in 

Subtract 367 from both sides of the equation

Rewrite the above equation as:

Divide both sides by 8

Remove decimal (do not approximate)

This means that:
