C. Region D
Step-by-step explanation:
Just plug the equations into desmos the calculator will graph it and show you with colors where the solution is.
Answer:
Explanation:
<u>1) Name the two variables:</u>
With that, the net rates of the boat down the river and upstrean are:
<u>2) Now set the equations for the distance as a function of the times and the rates:</u>
<u>3) Set the system of equations:</u>
<u>4) Solve the system by </u><u>elimination</u><u>:</u>
4 = 6.5 - c ⇒ c = 6.5 - 4 = 2.5
<u>5) Results:</u>
Given:
Anita's fixed salary = Rs. W
Bonus = Rs. Z for every bedcover sold by her.
To find:
Her total earnings if she sold 46 bedcovers.
Solution:
We have,
Bonus if she sold 1 bedcover = Rs. Z
Bonus if she sold 46 bedcover = Rs. Z × 46
We know that,
Total earnings = Fixed salary + Bonus
=
Therefore, the correct option is (b).
The equivalent percentage point drop = 10%
The percentage point change is the difference between the final and initial values.
The percentage change is the difference between the final and initial values
divided by the initial value
It is required to decrease the dropout rate from 30% to 20%
The point change = 20 - 30 = -10 (-ve change ⇒ decrease)
The percentage change = %
So, the equivalent percentage point drop = <u>10%</u>
And the percentage change = <u>33.33%</u>
