Answer:
z=12500
Step-by-step explanation:
Of means multiply and is means equals
85% *z = 106250
Change to decimal form
.85z = 106250
Divide each side by .85
.85z/.85 = 106250 /.85
z=12500
Answer:
The range is y > 0
Step-by-step explanation:
3^x is always greater than 0 and cannot be negative unless x is not real
Answer:
Domain of the function is (inf, -inf)
Step-by-step explanation:
G(x) = (25 - x)/5 First lets call g(x) by its other name - y
y = (25 - x)/5 Now switch the x and y
x = (25 - y)/5 Solve for y which is now the inverse - call this

5x = 25 - y
y = 25 - 5x this is the inverse so

= 25 - 5x
