Answer:

(22, - 24)

Step-by-step explanation:

Multiply the first equation by -5 to make the y's so you can add the up to zero.

-5(2x + y = 20)

-10x - 5y = -100 Add the second equation thn solve for x

6x + 5y = 12

-4x = -88

x = 22

Plug 22 in for x in either equation

2x + y = 20

2 (22) + y = 20

44 + y = 20

y = -24

What is CD? Show steps please!

Romashka [77]

Answer:

$\large\boxed{CD=2\sqrt6\ cm}$

Step-by-step explanation:

ΔDAC and ΔDCB are similar (AA). Therefore the sides are in proportion:

$\dfrac{CD}{DA}=\dfrac{DB}{CD}$

We have DA = 3cm and DB = 8 cm. Substitute:

$\dfrac{CD}{3}=\dfrac{8}{CD}$ cross multiply

$CD^2=(3)(8)$

$CD^2=24\to CD=\sqrt{24}$

$CD=\sqrt{4\cdot6}\\\\CD=\sqrt4\cdot\sqrt6\\\\CD=2\sqrt6\ cm$
