Answer:
(3,2) Choice C
Step-by-step explanation:
x-2y = -1
2x+3y =12
multiply the first equation by -2
-2x +4y = 2
add the 2 equations together
2x+3y =12
-2x +4y = 2
-----------------
7y =14
divide by 7
y =2
x-2y = -1
x -2(2) = -1
x-4 = -1
add 4 to each side
x = 3
(3,2)
Answer:
{5,6,7}
Step-by-step explanation:
3s>12
divide by 3 on both sides and you get
s>4
so {5,6,7} is the only one that works since it needs to be greater than 4

That is my final answer so I maybe wrong so don't take my word for it
Answer:
c = 4
Step-by-step explanation:
Let the common difference be c. Then a(n) = -3 + c(n-1). Since a(15) = 53, a(15) = -3 + (15-1)c = 53. Therefore, -3 + 14c = 53, or 14c = 56; c = 4.
Answer:
yes
