$4y+10$
Work Step by Step
RECALL:
The distributive property states that for any real numbers a, b, and c:
$ac+bc= (a+b)c$
Add the polynomials by regrouping the terms and then combining like terms using the distributive property to obtain:
$(-5y-3)+(9y+13)
\\= (-5y+9y)+(-3+13)
\\=(-5+9)y + 10
\\=4y+10$
