Answer:

Answer is B

Step-by-step explanation:

12x - y = 25 \\ 9x + y = 17 \\ x =  \frac{17 - y}{9}  \\ 12( \frac{17 - y}{9} ) - y = 25 \\

\frac{204}{9}  -  \frac{12}{9} y - y = 25 \\  \frac{204}{9}  -  \frac{21y}{9}  = 25 \\  -  \frac{21y}{9}  = 25 -  \frac{204}{9}  \\  -  \frac{21y}{9} =  2.33 \\ - 21y =  20.997 \\ y =  - 0.99

y =  - 1 \\ x =  \frac{17 - y}{9}  \\ x =  \frac{17 -  - 1}{9}  =  \frac{18}{9}   \\ x = 2

-2^2-3(-2)+1 evaluate the polynoimal
Phoenix [80]

We must follow order of operations rules (PEMDAS) here: exponentiation first, followed by multiplication and division, followed by addition and subtraction.

Thus, -2^2-3(-2)+1 becomes:

-[4] + 6 + 1 = 2 + 1 = 3 (answer)
