Answer:

Step-by-step explanation:

Using ZPP we get x = 0, 2x + 4 = 0, x + 5 = 0. Solving these, we get x = 0, x = -2, x = -5.

Which is a rational function??

snow_tiger [21]

Answer:

A. $y=\frac{x-5}{2}$

B. $y=\frac{2}{x}$

and

D. $y=x^2-x+4$

Step-by-step explanation:

A rational function is of the form $R(x)=\frac{P(x)}{Q(x)} ,Q(x)\ne0$ where

$P(x)$ and $Q(x)$ are polynomial functions.

Based on this definition, every polynomial function is a rational function.

Hence the rational functions in the options provided are;

A. $y=\frac{x-5}{2}$

B. $y=\frac{2}{x}$

and

D. $y=x^2-x+4$

$y=\frac{x-3^x}{x^2}$ is not a rational function because the numerator is not a polynomial function.

Vedmedyk [2.9K]

$\\ \sf\longmapsto 2:3=1:n$

$\\ \sf\longmapsto \dfrac{2}{3}=\dfrac{1}{n}$

$\\ \sf\longmapsto 2n=3$

$\\ \sf\longmapsto n=\dfrac{3}{2}$

In systems by substitution what is y=x+8 and x+y=2

LenKa [72]

Answer:

x = -3

Step-by-step explanation:

y = x + 8 and x + y = 2

Using substitution, we know that y = x + 8, so:

x + y = 2

x + (x + 8) = 2

2x + 8 = 2

2x = -6

x = -3

Then we solve for y:

x + y = 2

-3 + y = 2

y = 2 + 3

y = 5
