Intersecting chords are chords that intersect one another at a point
The value of n is -18
<h3>How to determine the value of n</h3>
Using the intersecting chord theorem, we have:
![\frac{7}{n + 4} = \frac{5}{n + 8}](https://tex.z-dn.net/?f=%5Cfrac%7B7%7D%7Bn%20%2B%204%7D%20%3D%20%5Cfrac%7B5%7D%7Bn%20%2B%208%7D)
Cross multiply
![7n + 56 = 5n + 20](https://tex.z-dn.net/?f=7n%20%2B%2056%20%3D%205n%20%2B%2020)
Collect like terms
![7n - 5n =20 - 56](https://tex.z-dn.net/?f=7n%20-%205n%20%3D20%20-%2056)
Evaluate the differences
![2n =-36](https://tex.z-dn.net/?f=2n%20%3D-36)
Divide through by 2
![n = -18](https://tex.z-dn.net/?f=n%20%3D%20-18)
Hence, the value of n is -18

Answer:
Step-by-step explanation:
a)4a-6a d)2x+4y-10x
=-2a. =-8-+4y
b)14-1-10
=3
c)2+8
=10
e)answer is 6 x raised to the power 3
f)7x raised to the power 2-5x-y
Answer: x = 4
Step-by-step explanation:
Given : A coordinate grid with 2 lines.
One line, labeled f(x) passing through (- 3, 3), (0, 3), and the point (4, 3). (i)
The other line is labeled g(x) and passes through (- 4, -3), (0, 0), and the point (4, 3). (ii)
We generally denote x values as input values and y values as output values.
From (i) and (ii), the common point on both lines = (4,3)
Here, input value = 4
Output value = 3
Hence, the input value produces the same output value for the two functions on the graph : x=4
