Answer:

Infinitely many solutions.

Explanation:

In this case we gonna use ELIMINATION BY ADDITION method.For that first we are gonna eliminate the terms containing ( X ).

Equation no 1:

3x + 3y = 10

Equation no 2:

-9x - 9y = -30

Now multiply equation no 1 with (3 )

3(3x + 3y) = 3(10)

9x + 9y = 30 ( equation no 1 )

Now ADD both the equations

9x + 9y = 30

 -9x - 9y =-30

0 = 0

If two chords intersect each other inside a circle, the products of their segments are equal.

7(n+4) = 5(n+8)
7n + 28 = 5n + 40
7n - 5n = 40 - 28
2n = 12
n = 6

Point N is on line segment MO. Given MN = x, MO = 3x - 6,

finlep [7]

Answer:

Step-by-step explanation:

N is between points M and O

MN = x

MO = 3x - 6

NO = x + 1

The way it reads MN + NO = MO

x + x + 1 = 3x - 6

2x + 1 = 3x - 6

2x - 2x +1 = 3x -2x - 6

1 = x - 6

1 + 6 = x

x = 7

MO = 3x - 6

MO = 3*7 - 6

MO = 21 - 6

MO = 15
