Ok so the way is find the area of the triangle

find the area of the circle

area of triangle-area of circle=shaded

triangle area=(1/2)base times height

circlearea=pi(radius)^2

** Value of x for which the two points are on the line with the given slope (1,-1) and (x,7): undefined is **** .**

<u>**Step-by-step explanation:**</u>

Here we have to Find x so that the two points are on the line with the given slope (1,-1) and (x,7): undefined . Let's find out:

We know that for any two points given as slope of line is determined by :

⇒

According to question we have two points as ∴

⇒

⇒

But **slope is undefined which is only possible when denominator is zero i.e.**

**⇒ **

⇒

Therefore ,** Value of x for which the two points are on the line with the given slope (1,-1) and (x,7): undefined is **** .**

The equation in y=mx+b form is: Y=2x+10

C - 9 < = 20

Add 9 to both sides

c -9 + 9 <= 20 + 9

c <= 29

So percent is x/100

total used/total possible=30.7/2870=0.01069 or 0.01069/1 round up and get 0.017

percent is x/100 so to convert 0.0107/1 to x/100 you mutiply the whole thing by 1 or 100/100 so

1.07% is used
