[tex]\langle-30,26\rangle[/tex]

1) Since we have this expression, let's do it in parts.

[tex]\begin{gathered} 4\langle-4,4\rangle-2\langle7,-5\rangle \\ x-component=4(-4)-2(7)=-16-14=-30 \\ y-component=4(4)-2(-5)=16+10=26 \\ \end{gathered}[/tex]

Note that since each vector has two components x, and y. The resultant will be the vector:

[tex]\langle-30,26\rangle[/tex]
