Answer:

Step-by-step explanation:

$(f\circ g)(x)=f(g(x))\\\\(f\circ g)(2) = f(g(2)) = f(2\cdot 2+3) = f(7)\\\\=4\cdot 7-1=\boxed{27}$

Answer:

parallel = same slope (-2x)

so it's y=-2x + b

let's find b by plugging in 1 for x and 3 for y (the coordinates)

3 = -2*1 + b

3 = -2 + b

5 = b

there you have it:

y = -2x +5

brainliest would really be appropriated (possible when someone else also leaves an answer)
