Answer:

Alyssa work at job A 9\ hours

Step-by-step explanation:

Let

x------> the number  of hours at work A

y------> the number  of hours at work B

we know that

x+y=24

y=24-x -----> equation A

6x+8.5y=181.5 -----> equation B

substitute equation A in equation B

6x+8.5(24-x)=181.5

6x+204-8.5x=181.5

8.5x-6x=204-181.5

2.5x=22.5

x=22.5/2.5

x=9\ hours

What is the average rate of change for this exponential function for the interval from x = 2 to x = 4?
Hunter-Best [27]

Answer:

The average rate of change over the interval is 120

Step-by-step explanation:

For a function f(x) the average rate of change over an interval [a,b] is given as;

f(b)-f(a)/b-a

in this case, a is 2 and b is 4

f(b) is 256 and f(a) is 16

Substituting these values in the equation for rate of change, we have;

(256-16)/(4-2) = 240/2 = 120
