Hello from MrBillDoesMath!
Answer:
-6.9
Discussion:
1.3n - 0.03 = -9 => multiply both sides by 100
130n - 3 = -900 =>
130n = -900 +3 = -897 => add 3 to both sides
n = -897/130 =>
n = - (69 * 13)/ (10*13) =>
n = - 69/10 = - 6.9
Thank you,

Answer:
A. (1, 0)
Reason:
When the first equation is graphed: y <u><</u> x + 1, the left side of the line is shaded and when the second equation is graphed: y <u><</u> x^2 -3x, the bottom is shaded.
The green section does not contain solutions. So D is automatically out.
The red section does not contain solutions as well. So C is automatically out.
For choice B, the point goes out of the shaded blue section, so that's out also.
As for choice A its in the blue shaded section, which makes that answer correct.
(when the two equations are within each other and combine a color, then whatever points is within the shaded part is the right answer)
