Answer:

$\large\boxed{z=\dfrac{1-c}{4+b}}$

Step-by-step explanation:

$-4z+1=bz+c\qquad\text{subtract 1 from both sides}\\\\-4z=bz+c-1\qquad\text{subtract}\ bz\ \text{from both sides}\\\\-4z-bz=c-1\qquad\text{change the signs}\\\\4z+bz=1-c\qquad\text{distribute}\\\\(4+b)z=1-c\qquad\text{divide both sides by}\ (4+b)\neq0\\\\z=\dfrac{1-c}{4+b}$

Which of the following statements must be true about the polynomial function f(x)? If 1+ the sqrt of 13 is a root of f(x), then

son4ous [18]

The correct answer is: if $1 + 13i$ is a root of $f(x)$ , then $1 - 13i$ is also a root of $f(x)$ .

In fact, every polynomial has real and/or complex solutions. If all solutions are real, we're good. But if not all of them are real, then the complex ones come in couple of conjugate solutions. Since $1 + 13i$ and $1 - 13i$ are conjugate complex numbers, if one of them is a solution, the other must be as well.

kari74 [83]

Answer:

57:38

Step-by-step explanation:

3/2(19):x

3:2

3x = 2 * 3/2 * 19

3x = 57

x = 19

Since the ratio is 3:2, then the scores at half-time were 57:38
