Answer:
The number will be -63
Step-by-step explanation:
Here, we want to give the number of the chosen 25th student
We can see that the numbering follows an arithmetic sequence where a = 9 and d which is the common difference is (6-9) = -3
Mathematically, we can calculate the nth term using the equation below;
Tn = a + (n-1)d
in this case, n = 25, a = 9 and d = -3
So we have
Tn = 9 + (25-1)-3
Tn = 9 -3(24)
Tn = 9-72
Tn = -63
Answer:
x = 4
y = -7
Step-by-step explanation:
y = -2x + 1
4x + y = 9
4x + y = 9
4x + (-2x + 1) = 9
4x - 2x + 1 = 9
2x + 1 = 9
2x = 9 - 1
2x = 8
x = 8/2
<u>x = 4</u>
4x + y = 9
4(4) + y = 9
16 + y = 9
y = 9 - 16
<u>y = -7</u>
