Each chord is cut into two segments at the point of where they intersect. One chord is cut into two line segments A and B. The other into the segments C and D. This theorem states that A×B is always equal to C×D no matter where the chords are.

Solve the system of equations using elimination.<br><br> 4x - 7y = 5<br> 9x – 7y = –15
Anni [7]

Step-by-step explanation:

We have to get one positive 7y so,

4x-7y=5

9x-7y=-15

multiply anyone of the equation by -1. I choose the first one so,

4x+7y=-5

9x-7y=-15

we can now cancel the y's so the equation will be left with

-4x=-5

9x=-15

add the equations

5x=-20

divide by 5 n u get

x=-4

now plug in the x value in any one of the

equations

I choose the first one so,

4(-4)-7y=5

-16-7y=5

add 16 to both sides

-7y=21

divide by -7

y=-3.

finally check.

Find the slope of the line passing through each of the following pairs of points.
BARSIC [14]

Look carefully at the first pair:  (−3, 9), (−3, −5)  Note that x does not change, tho' y does.  This is how we recognize a vertical line (whose slope is undefined).  The equation of this vertical line is x = -3.

Looking at the second pair:  from (3,4) to (5,6), x increases by 2 and y by 2; thus, the slope is m = rise/run = 2/2 = 1.

Third pair:  as was the case with the first pair, x does not change here, and thus the equation of this (vertical) line is x=0 (which is the y-axis).  The slope is undefined.

the ratio of sadia's age to her father's age is 3:6. The sum of their age is 96 .What is sadia's age​
max2010maxim [7]

We have,

a:b=3:6,a+b=96

Introduce variable x such that a=3x,b=6x

The sum a+b=96 is therefore 9x=96\implies x=10.\overline{6}

So,

a=3\cdot10.\overline{6}=\boxed{32} (sadia's age)

b=6\cdot10.\overline{6}=\boxed{64} (father's age)

Hope this helps :)
