The answer is 0.625 I am not so sure
Answer:
Option B
Step-by-step explanation:
First make x = 4 and y = 3 in the equation y = -1/2x + 5
it should look like 3 = -1/2(4) + 5 now we can solve
-1/2 * 4 = -2 → 3 = -2 +5
-2 + 5 = 3 → 3 = 3
Answer:








Step-by-step explanation:
Given



Solving (a): NK
MK is a diagonal and NK is half of the diagonal. So:



Solving (b): JL
JL is a diagonal, and it is twice of NL.



Solving (c): KL
To solve for KL, we consider triangle KNL where:

and





Solving (d - h):
To do this, we consider triangle JKN
-- diagonals bisect one another at right angle
Alternate interior angles are equal. So:

Similarly:


So:







we know that
arithematic sequence will always have common difference
(a)
−5, −7, −10, −14, −19, …
we can see that


they are not equal
so, this is not arithematic sequence
(2)
1.5, −1.5, 1.5, −1.5, …
we can see that


they are not equal
so, this is not arithematic sequence
(3)
4.1, 5.1, 6.2, 7.2, …
we can see that


they are not equal
so, this is not arithematic sequence
(4)
−1.5, −1, −0.5, 0, …
we can see that


they are equal
so, this is arithematic sequence
