Answer:
b. x + 1
Step-by-step explanation:
x¹⁶ − x¹⁴ = k (x¹⁵ − x¹⁴)
x¹⁴ (x² − 1) = k x¹⁴ (x − 1)
x² − 1 = k (x − 1)
(x − 1) (x + 1) = k (x − 1)
x + 1 = k
Answer:
6.3
Step-by-step explanation:
You can find the distance with a distance formula (need the points and it has a big, long square root) BUT, when you have an image like this graph you can totally see a right triangle and use the Pythagorean Theorem (distance formula is derived from Pythagorean theorem anyway) see image
Answer:
18
Step-by-step explanation:
Divide with by paratheses first. Use PEMDAS method
49/9 because if you simplify it, it would be 7/3 which is equal to the original ratio.
Answer:
A, B, C, and D, all options are correct.
A is correct because,
∠2 and ∠3 are corresponding angles.
B is correct because,
∠5 and ∠7 are corresponding angles.
C is correct because,
∠2 and ∠4 are corresponding angles.
D is correct because,
∠5 and ∠6 are alternate interior angles.
Note,
If two lines parallel, then
- Corresponding angles are equal.
- Alternate interior angles are equal.
