Answer:
100
Step-by-step explanation:
5•10^-2= 5•1/100 an d that's equal to 1/20 if you divide it with (2•10^3)wich is equal too 2000
you will get 100 as a result
To find the inverse, switch the x and y, and then solve for y (f(x) is the same as y)
So we get:
x=1.50y-30 (add 30 to both sides)
x+30=1.50y (divide both sides by 1.5)
x/1.5+30/1.5=y
y=x/1.5+20
Hope this helps
