x=4 y=5
if we put two pharases together
the answer is as follows pic :
x=4 y=5
1) an = a1 + d*(n-1) => a20 = -4 + (-9)*19 = -4 - 171 = - 175
1) ---> C)
2) a81 = 20 + 4*80 = 340;
2) ---> A)
3) a12 = ?
3) ---> B) or D).

Answer:
Step-by-step explanation:
x+y=7 Coordinate (1,7)
Y=2x+1
answer is png image
35 : 10 = 7*5 : 2*5 = 7 : 2
Thus 35 : 10 = 7 : 2;
but 35:10 ≠ 7:5
