3x2 is six. If you do that across, you would get 6/6 for both. 6/6 - 6/6 is how much?
<span> 9-4x=57
-4x = 57 - 9
-4x = 48
x = -12</span>
I think that it might be 5... ? I'm not sure though don't blame me if its wrong.
Answer:
a = 9, b = 3
Step-by-step explanation:
The exponential function is
y = a 
Find a and b by using the points it passes through
Using (0, 9 ) then
9 = a
(
= 1 )
a = 9
y = 9 
Using (3, 243 ) then
243 = 9b³ ( divide both sides by 9 )
27 = b³ ( take the cube root of both sides )
b =
= 3
y = 9
← exponential equation
