E.) X^Y + 1 = 2 not linear

Step-by-step explanation:

linear functions are in terms on x and y, no exponentials

A.) 9Y + 3 = 0 linear

B.) Y - 4X = 1 linear

I need help with 2b.

Answer:

The answer to your question

a) Values excluded = -2, 0

b) solutions = -2/3, 2

Step-by-step explanation:

Equation

$\frac{4x}{2x + 4} = \frac{x+ 2}{2x}$

a) x is restricted when the denominators equal zero, so let's get them.

2x + 4 = 0 2x = 0

2x = - 4 x = 0 / 2

x = -4 / 2 x = 0

x = -2

x must be different to -2, 0

b) $\frac{4x}{2x + 4} = \frac{x+ 2}{2x}$

$\frac{2x}{x + 2} = \frac{x + 2}{2x}$

4x² = (x + 2)²

4x² = x² + 4x + 4

4x² - x² - 4x - 4 = 0

3x² - 4x - 4 = 0

3x² - 6x + 2x - 4 = 0

3x(x - 2) + 2(x - 2) = 0

(x - 2)(3x + 2) = 0

x₁ - 2 = 0 3x₂ + 2 = 0

x₁ = 2 x₂ = -2/3

Im giving 30 points pls help

gayaneshka [121]

Step-by-step explanation:

Pathagory and Theorem

a^2+b^2=c^2

(x-3)^2+(x-4)^2=6^2

expand:

2x^2-14x+25=36

2x^2-14x-11=0

x=(\sqrt{71}+7)/2

perimeter=(x-3)+(x-4)+6=2x-1

insert the value for x into 2x-1

$\sqrt{71}$ +6=perimeter

Hope that helps :)
