=

equals
k = 15.6
First, simplify

to 1.2. Your problem should look like:

= 1.2
Second, multiply both sides by 13. Your problem should look like: k = 15.6, which is the answer.
Answer: The answer is (A)
and (C)
Step-by-step explanation: We are given a graph with a point A having co-ordinates (3, 4) and origin O(0, 0). We are to find the slope and equation of line OA.
Since O(0, 0) and A(3, 4) are two points on the line OA, so its slope will be

And the equation of the line will be

Thus, the correct options are (A) and (C).
Answer:
x = 5 unit
Step-by-step explanation:
The given figure represent the theorem of circle,
It two chords of circle intersect outside or inside when produce, then
AP × PB = DP × PC
SO , from given data we can find the X
Now, (X + 4) × 4 = (9 + 3) × 3
Or, X + 4 = 
Or, X + 4 = 
Or, X = 9 - 4
∴ X = 5 unit
