\(-3z - 5z = -8z\)

Solución

\( -3z - 5z \) can be simplified by combining like terms. 1. Combine the coefficients: \[ -3 - 5 = -8 \] 2. Multiply by \( z \): \[ -8z \] Thus, \[ -3z - 5z = -8z \]

When you combine the like terms in the expression \(-3z - 5z\), you add the coefficients together. So, \(-3 - 5\) gives you \(-8\). Therefore, \(-3z - 5z = -8z\). So, the simplified expression is \(-8z\).

A patient takes vitamin pills. Each day she must have at least 420 IU of vitamin \( \mathrm{A}, 12 \mathrm{mg} \) of vitamin \( \mathrm{B}_{1} \), and 90 mg of vitamin C . She can choose between pill 1 , which contains 90 IU of vitamin \( \mathrm{A}, 2 \mathrm{mg} \) of vitamin \( \mathrm{B}_{1} \), and 10 mg of vitamin C , and pill 2 , which contains 60 IU of vitamin \( \mathrm{A}, 2 \mathrm{mg} \) of vitamin \( \mathrm{B}_{1} \), and 25 mg of vitamin C . Pill 1 costs \( 25 \phi \), and pill 2 costs \( 75 \phi \). How many of each pill should she buy in order to minimize her cost? What is the minimum cost? She should buy \( \square \) of pill 1 and \( \square \) of pill 2 . The minimum cost is \( \$ \square \). (Simplify your answers. Type integers or decimals.)

She plans to invest at least \( \$ 5 \) million in bonds and at least \( \$ 20 \) million in mutual funds. Bonds have an initial fee of \( \$ 100 \) per million dollars, while the fee for mutual funds is \( \$ 200 \) per million. The fund manager is allowed to spend no more than \( \$ 8000 \) on fees. How much should be invested in each to maximize annual interest? What is the maximum annual interest? The amount that should be invested in Treasury bonds is \( \$ \square \) million and the amount that should be invested in mutual funds is \( \$ \square \) million.
