Answer:

A

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.

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
