Answer:

x=40/9

Step-by-step explanation:

$\frac{x}{16} = \frac{10}{36} |first \: you \: cross \: multiply| \\ x(36) = 16(10) |open \: bracket | \\ 36x = 160 |divide \: both \: side \:by \: 36 | \\ \frac{36x}{36} = \frac{160}{36} \\ x = \frac{40}{9}$

If someone could help I would really appreciate it! <br> U CAN DO IT

This is point slope form so you start with
y-b = m(x-a)
then you would find a point (5, - 1)
then fill in
y-5 = 3(x-1)
then if you want solve it for slope intercept form
y = 3x + 2
graph that and check your work

Write a polynomial function of minimum degree with real coefficients whose zeros include those listed. Write the polynomial in s

aleksandrvk [35]

This is going to be a fourth degree polynomial because if x = 4, one of the factors is x - 4; if x = -2, then one of the factors is x + 2; and by the conjugate root theorem, if x = -1 + 2i, then -1-2i HAS to also be a root. If x = -1+2i, then the factor is (x-(-1+2i)). Simplfying that gives us (x+1-2i). Likewise, if x = -1-2i, then the factor is (x-(-1-2i)). Simplifying that gives us (x+1+2i). We will FOIL those complex factors first. Doing that we have $x^2+x-2ix+x+1-2i+2ix+2i-4i^2$ . Once we simplify that down it's much easier to deal with than what it looks like right now. $x^2+2x+1-4i^2$ . Since i^2 = -1, what we have in the end is $x^2+2x+5$ . Now we will multiply that by x-4. $(x^2+2x+5)(x-4)=x^3-2x^2-3x-20$ . Now finally we will multiply in the last factor of x+2. $x^4-7x^2-26x-40$ is your final fourth degree polynomial.
