Mathematics

Given:

Diagram of a circle and its two secant from an exterior point.

To find:

The value of x.

Solution:

We know that, If two secant are on a circle from an exterior point, then the products of measure of secants and measure of external segments of secants are equal.

Using the above property, we get

(x+7)x=(2+2)2

x^2+7x=(4)2

x^2+7x=8

x^2+7x-8=0

Splitting the middle term, we get

x^2+8x-x-8=0

x(x+8)-1(x+8)=0

(x+8)(x-1)=0

Using zero product property, we get

(x+8)=0 and (x-1)=0

x=-8 and x=1

Side cannot be negative.

Therefore, the only possible value of x is 1.

Answer:

30(x+1)/(x+7)

Step-by-step explanation:

This is not a rational expression because denominator has a domain of which it can be undefined.

To rationalize multiply by the reciprocal of the denominator (1/6+1/x+1)

___<u>5___ </u>*(6)(x+1) --> _____<u>30(x+1)_____</u> --><u> 30x+1</u>_ --> <u>30x+1</u>

1/6+1/x+1   *(6)(x+1)--> 6(x+1)/6 + 6(x+1)/(x+1) --> (x+1)+6 --> x+7

Final Answer: 30(x+1)/(x+7)

Answer:

y=-3x+7

Step-by-step explanation:

y=mx+b is the formula you are going to end up once completed.

This, by given two points:

(4,-5) (3,-2)

\frac{-2-5}{3-4} = Point-Slope Intercept Form

\frac{3}{-1} = After subtracting both from above

-3 = is your slope, decreasing.

Substitute -3 for y=mx+b

y=-3x+b

Use one of the given points (any) to find what b equals.

(4,-5)

x    y

-5=-3(4)+b

-5= -12+b

7=b

Final Equation:

y=-3x+7
