Answer:
10x2 + 2x + 13.
Step-by-step explanation:
10x2 + 3 - (-2x - 10) (Note you have to put the -2x - 10 in brackets).
= 10x2 + 3 + 2x + 10 (Distributing the negative over the brackets).
= 10x2 + 2x + 13.

Answer:
12x -y = -87
Step-by-step explanation:
You can start with the 2-point form of the equation of a line and manipulate it to give you the standard form.
y = (y2 -y1)/(x2 -x1)(x -x1) +y1
y = (-9 -3)/(-8 -(-7))(x -(-7)) +3
y = (-12/-1)(x +7) +3
y = 12x +84 +3
-12x +y = 87 . . . . . subtract the x-term
12x -y = -87 . . . . . . make the leading coefficient positive (per standard form)
Relative frequency = (number of times an item appears) /(TOTAL numbers)
Relative frequency (selecting Red ) = 13/30 =0.434
