Complete the ordered pair for the equation \( \mathrm{y}=-10 \mathrm{x}+18 \) \( (\ldots, 78) \)

a. \( \frac{2 x^{3}+6 x-6}{x^{3}-1} \)

In the \( x y \)-plane, a parabola has vertex \( (9,-14) \) and intersects the \( x \)-axis at two points. If the equation of the parabola is written in the form \( y=a x^{2}+b x+c \) where \( a, b \), and \( c \) are constants, which of the following could be the value of \( a+b+c \) ? (A) -23 (B) -19 (D) -12

Roger was told to think of a number, add 20 , then divide the result by 3 . The answer was Jower than Roger's original number. Deteruine the range of possible numbers Roger may have originally chosen.

1) \( \frac{10 x+8}{3 a-b}-\frac{9 x+5}{3 a-b}= \)

tinh \( a x^{2}+2 x+3 y=6 \)
