To find 
, you can switch the x and the y(which is f(x)).
So instead of 
, it will be:
Now you need to find "y".
You first multiply (4y - 5) on both sides
Next divide "x" on both sides
Add 5 on both sides
Divide 4 on both sides to get "y" by itself
Hi! Answer is "the initial velocity of the runner was 4 m/s, and the runner stopped after 8 seconds".
This is a velocity - time graph.
At t = 0 s, the graph has a velocity as 4 m/s. This means, the runner has an initial velocity as 4 m/s.
At t = 4 s, the runner has reached his maximum velocity as 8 m/s and acceleration is 1 m/s².
After t = 4 s, the velocity has decreased with the time means it is a negative acceleration.
At t = 8 s, the velocity of the runner has reached to zero means runner has stopped after 8 seconds.
Hello!
We can write an expression to show this scenario. Write this in the equation format y = mx + b:
m = rate of change, or cost per ride
b = initial cost, or cost to enter the fair
y = 2.50x + 4
Solve for the amount of rides possible with $21.50:
21.50 = 2.50x + 4
Subtract 4 from both sides to isolate x:
17.50 = 2.50x
Divide both sides by 2.50:
17.50/2.50 = 7 rides.
Answer:
<em><u>1.6</u></em>
Step-by-step explanation:
The Mean Absolute Deviation (MAD) is the distance each number is away from the mean divided by the amount of numbers.
15 is 4 away from 19, for example
So:
19 - 15 = 4
25 - 19 = 6
19 - 13 = 6
19 - 15 = 4
19 - 18 = 1
20 - 19 = 1
22 - 19 = 3
24 - 19 = 5
4 + 6 + 6 + 4 + 1 + 1 + 3 + 5 = 30
30/19 = 1.5789, rounded to 1.6
Answer:
-9
Step-by-step explanation:
-b+5=-4+4b-6b
5+4=4b-6b+b
9=-b
divide both side by -1
therefore b=-9
