D. 10 ( 2 x − 1 )
Step-by-step explanation:
Given expression:
20x − 10
Find the equivalent expression
Check all that applies
A. 2 ( 10 x − 5 )
= 20x - 10
B. 2 ( 2 x − 1 )
= 4x - 2
C. 10 ( 20 x − 10 )
= 200x - 100
D. 10 ( 2 x − 1 )
20x - 10
The correct options are
A. 2 ( 10 x − 5 )
D. 10 ( 2 x − 1 )
Answer:
-16
Step-by-step explanation:
To answer this question you must know that there is a theorem called the "Two secants angle theorem", which establishes that the measure of an angle formed when two secants intersecting outside the circle is equal to 1/2 the difference of the two intercepted arcs.
Therefore, as you can see, the correct answer is the option B): B)<span>1/2 the difference of the intercepted arcs</span>
Formula to find the length of two endpoints: 
Now, solve with the given endpoints.

Answer:
y = 2x - 1
Step-by-step explanation:
Consider the differences between consecutive values of y. If constant then this value is the multiplier.
1 - (- 1) = 3 - 1 = 5 - 3 = 7 - 5 = 9 - 7 = 2 ← constant difference, hence
y = 2x
Given the point (0, - 1 ) then we require to subtract - 1, that is
y = 2x - 1 ← equation relating x and y
