Well, instead of doing 3*3*3*3*3*3*3
You could just do
Y=6, X=8, t=3/2 then dx/dt=5.33 or 16/3

The slope is the difference of the y-coordinates divided by the difference of the x-coordinates, which gives us 5/2, or 2.5
Answer:
Hello
The answer is 30% increase in texts since last month.
IF you feel any problem in understanding , do comment pls.
Step-by-step explanation:
Let
X = last month sent texts
y = this month sent texts
First of all find the no. of increased texts,
by subtracting x from y
=> y-x= 7085- 5450
= 1635
We want to find these 15 texts % with respect to 5450 texts
i.e. 1635/X
=0.30
for answer in % multiply with 100
i.e. 30%
