To check if \(-4\) is the solution to the equation \(3x - 4 = 2x - 8\), substitute \(-4\) for \(x\): \[ 3(-4) - 4 = 2(-4) - 8 \] Calculate both sides: \[ -12 - 4 = -6 - 8 \] This simplifies to: \[ -16 = -14 \] Since \(-16\) does not equal \(-14\), \(-4\) is **not** the solution to the equation.

An animal breeder can buy four types of food for Vietnamese pot-bellied pigs. Each case of Brand A contains 25 units of fiber, 40 units of protein, and 40 units of fat. Each case of Brand B contains 100 units of fiber, 130 units of protein, and 110 units of fat. Each case of Brand C contains 275 units of fiber, 350 units of protein, and 310 units of fat. Each case of Brand D contains 200 units of fiber, 260 units of protein, and 200 units of fat. How many cases of each brand should the breeder mix together to obtain a food that provides 3975 units of fiber, 5100 units of protein, and 4440 units of fat? Brand B, z represent the number of cases of Brand C, and \( w \) represent be the number of cases of Brand D. There are four ways in which the breeder can mix brands to obtain a food that provides 3975 units of fiber, 5100 units of protein, and 4440 units of fat. If \( w=0 \), the solution is \( (0,15,9,0) \). If \( w=1 \), the solution is \( (1,10,10,1) \). If \( w=2 \), the solution is \( (\square, \square, \square, 2) \).

An investor plans to put a total of \( \$ 110,000 \) in a money market account, a bond fund, an international stock fund, and a domestic stock fund. She wants \( 60 \% \) of her investment to be conservative (money market and bonds). The investor wants the amount in international stocks to be one-fourth the amount in domestic stocks. Finally, the investor needs an annual return of \( \$ 4,400 \). Assuming the investor gets annual returns of \( 2.5 \% \) on the money market account, \( 3.5 \% \) on the bond fund, \( 4 \% \) on the international stock fund, and \( 6 \% \) on the domestic stock fund, how much should the investor put in each investment? The investor should put \( \$ 28600 \) in the bond fund. (Type a whole number.) The investor should put \( \$ \square \) in the international stock fund. (Type a whole number.)
