Answer 1

a)

$\frac{d}{dx}\left(2x+1\right)\\\\=\frac{d}{dx}\left(2x\right)+\frac{d}{dx}\left(1\right)\\\\=2+0\\\\=2$

b)

$\frac{d}{dx}\left(-5x+3\right)\\\\=-5+0\\\\=-5$

c)

$\frac{d}{dx}\left(x\right)\\\\=1$

d)

$\frac{d}{dx}\left(x-3\right)\\\\=\frac{d}{dx}\left(x\right)-\frac{d}{dx}\left(3\right)\\\\=1-0\\\\=1$
