Answer:
Step-by-step explanation:
Using Chord-Chord Power theorem:
=> (2)(x) = (4)(3)
=> 2x = 12
Dividing both sides by 2
=> x = 6

Determine if is a function of
Solving x+y=9
Make y the subject of formula
<em>Hence; y is a function of x</em>
Solving
Subtract x² from both sides
Square root of both sides
This implies that
or
<em>Because </em><em> can be any of those two expressions, it is not a function.</em>

Answer:
Common difference
Next three terms
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
Find the common difference by subtracting the previous term from a term. We can use the terms 1/4 and 1/2:
Convert 1/2 into a fraction over 4:
1/2 · 2/2 = 2/4
Find the common difference by subtracting the fractions:
2/4 - 1/4 = 1/4. This is the common difference.
Find the next 3 terms by adding 1/4:
5/4 + 1/4 = 6/4 (Reduce fraction) = 3/2
6/4 + 1/4 = 7/4
7/4 + 1/4 = 8/4 (Reduce fraction)
Therefore, the next 3 terms are 3/2, 7/4 and 2.
