Answer:
The common difference of the given AP is d=5.
Step-by-step explanation:
Given the sequence

An Arithmetic sequence has a constant difference 'd' and is defined by

Computing the common difference of all the adjacent terms


As the difference between all the adjacent terms is the same and equal to

Therefore, the common difference of the given AP is d=5.
Answer:
C
Step-by-step explanation:
it's C
sorry if I am wrong

We rewrite it in a more functional form:

I'll make a vertical table, easier to type. For each x we subtract 3 to get y.
x y
0 -3
1 -2
2 -1
3 0
Answer:
x=9, y=5. (9, 5).
Step-by-step explanation:
-4x+9y=9
x-3y=-6
-----------------
x=3y+(-6)
x=3y-6
-4(3y-6)+9y=9
-12y+24+9y=9
-3y=9-24
-3y=-15
3y=15
y=15/3
y=5
x-3(5)=-6
x-15=-6
x=-6+15
x=9
