- Mixture \( A \) is made with 5 cups of purple paint and 2 cups of white pain - Mixture \( B \) is made with 15 cups of purple paint and 8 cups of white Which mixture is a lighter shade of purple? Explain your reasoning.

blem 3. Find the linear approximation, \( L(x) \) of the function \( f(x)=x+\frac{1}{x} \) at \( x=2 \).

The result displayed was 9 E 23 for one computation. The result displayed was \( 7.79 \mathrm{E}-26 \) for another computation.

a) \( 3 x^{2}-\left\{3 x+2-\left[3 x^{2}+5 x-(4 x+6)-6 x+2\right]\right\} \) b) \( 3 x y-\left[5 x-3 x y+2 x-(7 x y-1)+\left(4 x^{2}-x y\right)\right]+x^{2}+5 \)

Subtract. Then simplify. If a denominator has three or more factors (other than monomials), leave it in factored form. \( \frac{v-3}{5 v+45}-\frac{v+7}{7 v+63} \)

\( n(a+16)^{2}=16 \). If there are \( m \) \( \varnothing \).
