Y=f (x) then x= g (y)
x=3y
solve x=3y for y
if f(x) = g(x),then in(f(x)).
in(x)= yin(3)
y= in(x) / in(3)
48 minutes!! If 2 quarters equals 12 minutes then you would do 8 divided by 2 which is 4 and then do 12 times 4

Answer:
The value of x is 3 and y is 6.
Step-by-step explanation:
You can solve this simultaneous equation by elimination method :











Answer:

Step-by-step explanation:
exponential function : 
where a = y intercept and b = factor ( what you multiply by )
looking at the table the y intercept is at (0,10) so a = 10
so we now have y = 10 * (b)^x
to find the factor we simply plug in one of the ordered pairs.
note that the ordered pair chosen does not effect the outcome
i chose (2,250)
we have y = 10 * (b)^x
(x,y) = (2,250)
250 = 10 * (b)^2
divide both sides by 10
25 = b^2
take the square root of both sides
5 = b
the final equation would be f(x) = 10 * (b)^x
