Answer:
The mean is 20
Step-by-step explanation:
17+19+21+23=80
80 div 4 = 20
Answer:
Step-by-step explanation:
See the attached graph.
The points (0,3) and (1,1) are on the graph of the exponential function.
Let the function be 
....... (1)
Now, satisfying the point (0,3) we get from the equation (1),
Therefore, the initial value of the function is a = 3
Hence, the equation becomes 
......... (2)
Now, satisfying the point (1,1) we get from equation (2)
⇒ b = 1/3
So, the final equation becomes (Answer)

i cant see it very well it is too small can you zoom it in some thx :)
Step-by-step explanation:
Answer:
y=-3x+15
Step-by-step explanation:
To find the equation of the line, you need to find the slope and y intercept. The slope is pretty easy, as the line goes down by 3 after going up by 1. This means that the slope is -3/1=-3. The y intercept is also pretty easy, as you know that the line will increase by 3 every time you go back 1 to the left. 3*4=12, meaning that going back 4 will take you up 12. 3+12=15, meaning that the equation of the line is y=-3x+15. Hope this helps!
OK so the value of A would be 7 because as you can see from the second to third step, Atraeus factored out 7 from both terms!
