Question

1. $f(x) = x + 6$
2. $g(x) = 3x$
3. $h(x) = -2x + 9$
4. $r(x) = -x - 7$
5. $p(x) = -3 + 4x$
6. $b(x) = 18 - 0.5x$
7. $v(x) = 12 - 2x - 5$
8. $u(x) = -1 - x + 4$

Explanation:

Step1: Simplify \( v(x) \)

Combine like terms in \( v(x) = 12 - 2x - 5 \). The constant terms \( 12 \) and \( -5 \) can be combined.
\( v(x)=(12 - 5)-2x \)
\( v(x)=7 - 2x \)

Step2: Simplify \( u(x) \)

Combine like terms in \( u(x)=-1 - x + 4 \). The constant terms \( -1 \) and \( 4 \) can be combined.
\( u(x)=(-1 + 4)-x \)
\( u(x)=3 - x \)

Answer:

Simplified functions: \( v(x)=7 - 2x \), \( u(x)=3 - x \)
