wel

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

Taking successive discounts of 15% off and then 25% off is the same as taking a one time discount of 40%. true or false
zysi [14]

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.

The sum of a number and three times its reciprocal is 52/7. Find both possible answers
weeeeeb [17]

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= \frac{-b+\sqrt{b^2-4ac}}{2a}  and x2= \frac{-b-\sqrt{b^2-4ac}}{2a}

so a=7, b=-52,c=21

x1=\frac{52+\sqrt{52^2-4*7*21} }{14}= (52+46)/14=98/14=7

x2=(52-46)/14=6/14=3/7
