Hello!


The graph, (2/5)^x is an exponential function.


Since there is not a negative symbol in the front of the function, options A and B are incorrect.


For option 3 to be correct, there would need to be a negative symbol in front of the exponent, x.


So therefore, the answer option 4. (Also, I'll post a graph. :))

Describe a situation that fits each equation. Describe more than one situation for each equation, if possible.
lisabon 2012 [21]

Answer:

Step-by-step explanation:

4x − 1 = 19

solving for x, x = 5

2x − 4 = 10

x=7

2x + 2y = 48

x=24-7

y=24-x

5x + 2y = 90

x=18-2y/5

y=45-5x/2

all the situations I could find hope this helps for each equation.
