Answer:

14.

$x = 11$ $m$ $m$ $m$

15.

$x = 4$ $WX = 25$ $XY = 17$ $WY = 25$

Step-by-step explanation:

Solving (14):

$BC = BD$

$m$

$m$

$m$

First, we solve for x.

Since sides $BC = BD$ , then

$m$

This is so because the theorem of ASA (Angle-Side-Angle)

So, we have:

$5x - 19 = 2x + 14$

Collect Like Terms

$5x - 2x = 19 + 14$

$3x = 33$

Divide both sides by 3

$x = 11$

Solving for m<B, m<C and m<D.

We simply substitute 11 for x in their respective expressions.

$m$

$m$

Solving (15):

$WX = 9x - 11$

$XY = 4x + 1$

$WY = 7x - 3$

First, we solve for x.

Since , then

$WX = WY$

This is so because the theorem of SAS (Side-Angle-Side)

So, we have:

$9x - 11 = 7x - 3$

Collect Like Terms

$9x - 7x = 11-3$

$2x = 8$

Divide both sides by 2

$x = 4$

Solving for WX, WY and XY

We simply substitute 4 for x in their respective expressions.

$WX = 9x - 11$

$WX = 9 * 4 - 11$

$WX = 36 - 11$

$WX = 25$

$XY = 4x + 1$

$XY = 4 * 4 + 1$

$XY = 16 + 1$

$XY = 17$

$WY = 7x - 3$

$WY = 7 * 4 - 3$

$WY = 28 - 3$

$WY = 25$

Find the break-even point for the firm whose cost function C and revenue function R are given.

katrin2010 [14]

The solution is
to find x, C(x) = <span>R(x)
</span>5x + 10,000 = <span>15x
</span> 10,000 = <span>10x, so x = 1,000</span>
