Let C represent the cost in dollars and R represent the revenue in dollars. What is the break-even point? Use a table to help if

BigorU [14]

Answer:

$x = 5$

$R = C = 225$

Step-by-step explanation:

Given

$C = 15x + 150$

$R = 45x$

Required

The break even point

To do this, we make use of:

$R =C$

$45x=15x + 150$

Collect Like Terms

$45x-15x = 150$

$30x = 150$

$x = 5$

Substitute 5 for x in $R = 45x$

$R = 45 * 5$

$R = 225$

Hence, the break even point is:

$x = 5$

$R = C = 225$

Subtract: 4x/x^2-25 - 2/x^2+2x-15

Alex777 [14]

Answer: $\dfrac{4x^2-14x+10}{(x-5)(x+5)(x-3)}$

Step-by-step explanation:

Given

Subtract the expression

$\Rightarrow \dfrac{4x}{x^2-25}-\dfrac{2}{x^2+2x-15}\\\\\Rightarrow \dfrac{4x}{(x-5)(x+5)}-\dfrac{2}{x^2+5x-3x-15}\\\\\Rightarrow \dfrac{4x}{(x-5)(x+5)}-\dfrac{2}{(x+5)(x-3)}\\\\\text{Take the LCM and subtract}\\\\\Rightarrow \dfrac{4x(x-3)-2(x-5)}{(x-5)(x+5)(x-3)}\\\\\Rightarrow \dfrac{4x^2-12x-2x+10}{(x-5)(x+5)(x-3)}\\\\\Rightarrow \dfrac{4x^2-14x+10}{(x-5)(x+5)(x-3)}$
