ANSWER

Alex needs to mix one pound of dried fruit with
1 \frac{1}{9}
pounds of walnuts.

EXPLANATION

It was given that, Alex mixes
\frac{2}{3}
pounds of walnuts with

\frac{3}{5}
pounds of dried fruit.


We can write the ratio,

\frac{2}{3} :  \frac{3}{5}

Let
x
represent how many pounds of walnuts Alex needs to mix with one pound of dried fruit.


Then we can again write the ratio,

x: 1
We can therefore write the proportion,


\frac{2}{3} :  \frac{3}{5}  = x: 1

This can be rewritten as,

\frac{ \frac{2}{3} }{ \frac{3}{5} }  =  \frac{x}{1}

We solve for x to obtain,

\frac{2}{3}  \times  \frac{5}{3}  = x


This implies that,

x =  \frac{10}{9}

x = 1 \frac{1}{9}

Hence Alex needs to mix
1\frac{1}{9}
pounds of walnuts with one pound of dried fruit.

5. Given (x + 1) and (x-3) are factors of P(x) = x4-5x³-7x² + cx + d. Determine the values
Iteru [2.4K]

By concepts of polynomials and systems of linear equations, the constants c and d of the expression p(x) = x⁴ - 5 · x³ - 7 · x² + c · x + d are 29 and 30.

<h3>How to determine the missing coefficients of a quartic equation</h3>

A value x is a root of a polynomial if and only if p(x) = 0. We must replace the given equation with the given roots and solve the resulting system of <em>linear</em> equations:

(- 1)⁴ - 5 · (- 1)³ - 7 · (- 1)² + (- 1) · c + d = 0    

- c + d = 1      (1)

3⁴ - 5 · 3³ - 7 · 3² + 3 · c + d = 0    

3 · c + d = 117       (2)

The solution of this system is c = 29 and d = 30.

By concepts of polynomials and systems of linear equations, the constants c and d of the expression p(x) = x⁴ - 5 · x³ - 7 · x² + c · x + d are 29 and 30.
