The solution the system x = -4y + 4; 2x + 8y = 8 has is: C. infinitely many solutions.
x = -4y + 4 (equation 1), can be rewritten as x + 4y = 4
2x + 8y = 8 (equation 2), devided by 2 on both sides: x + 4y = 4
Therefore, equation 1 and 2 are the same line, and there are infinite solutions to the line system.

3x – 4y = 9
–3x + 2y = 9
Adding the above equations: -2y = 18, y = 18/-2 = -9
3x – 4(-9) = 9
3x + 36 = 9
3x = 9 - 36 = - 27
x = -27/3 = -9
The solution for the sytem of equations 3x – 4y = 9; –3x + 2y = 9 is D. (–9, –9)

3x – 4y = –24 (equation 1)
x + y = –1 multiply 4 on both sides: 4x + 4y = -4 (equation 2)
Adding up equation 1 and equation 2 we get: 7x = - 28
so x = -28/7 = -4;
(-4) + y = –1,
y = - 1 + 4 = 3
The slotion for the system of equations 3x – 4y = –24; x + y = –1 is B. (–4, 3)

The solution of the system y = x + 5; y = –5x – 1 is (-1, 4)
y = x + 5
y = –5x – 1
Replace y in the second equation with the first one;
x + 5 = –5x – 1
x + 5x = - 1 - 5
6x = -6
x = -1
y = -1 + 5 = 4

The formula to represent the arithmetic sequence 130, 143, 156, 169, ... is: A(n) = 130 + (n-1)13
When n = 13,
A(13) = 130 + (13-1)13 = 130 + 156 = 286
