Answer:
point lies on circle
Step-by-step explanation:
Substitute the coordinates of the point into the left side of the equation and if equal to the right side then point lies on circle.
(4 - 1)² + (2 + 2)² = 3² + 4² = 9 + 16 = 25 = right side
Then point (4, 2 ) lies on the circle
a rectangle because a parallelogram has more squared so this makes it a rectangle since a rectangle is not as square
Answer:
False
Step-by-step explanation
Let's take the example starting number as 100
15% off of 100 gives us 85.
25% off of 85 is 63.45
40% off of 100 would be 60.
Answer:
x+3*1/x=52/7
7x^2/7x+21/7x=52x/7x
7x^2-52x+21=0
I solve this with the quadratic formula
Solution of ax^2+bx+c=0, a≠0 are :
x1= 
and x2= 
so a=7, b=-52,c=21
x1=
= (52+46)/14=98/14=7
x2=(52-46)/14=6/14=3/7
