Answer:
units.
Step-by-step explanation:
We have been given that Joy recorded the distances she walked each day for five days.
To find the distance traveled be Joy in 5 days we will add the distances covered by Joy each day.
As there are 3 dots on 1/3, this means that Joy traveled 1/3 units on 3 days.
Since there is 1 dot on 1/2 and on dot on 2/3, so this means that Joy walked 1/2 units one day and 2/3 units another day.
Let us add all these distances.
Let us have a common denominator.
Therefore, Joy traveled units in 5 days.
The inverse of the function are respectively; f⁻¹(3) = 2 and f⁻¹(8) = 8.5
<h3>How to find the inverse of a Function?</h3>
The formula to find the equation of this function using two coordinates is;
(y - y1)/(x - x1) = (y2 - y1)/(x2 - x1)
Using the first 2 coordinates, we have;
(y - 1)/(x + 1) = (3 - 1)/(2 + 1)
(y - 1)/(x + 1) = 2/3
3y - 3 = 2x + 2
3y = 2x + 5
y = ¹/₃(2x + 5)
Thus, the inverse is;
f⁻¹(x) = (3x - 5)/2
Thus;
f⁻¹(3) = (3*3 - 5)/2
f⁻¹(3) = 2
Similarly;
f⁻¹(x) = (3x - 5)/2
Thus;
f⁻¹(8) = (3*8 - 5)/2
f⁻¹(8) = 8.5

Answer:
<h2>B. y=25x+50</h2>
Step-by-step explanation:
We need to use two points on the line: (0,50) and (2,100).
Then, we find the slope with the formula
Then, we use the point-slope formula to find the equation
Therefore, the right answer is B.
