3x + ky = 8

sattari [20]

Answer:

(a): x is 3 and ky is -1

(b): k is -2

Step-by-step explanation:

Let: 3x + ky = 8 be equation (a)

x - 2 ky = 5 be equation (b)

Then multiply equation (a) by 2:

→ 6x + 2ky = 16, let it be equation (c)

Then equation (c) + equation (b):

${ \sf{(6 + 1)x + (2 - 2)ky = (16 + 5)}} \\ { \sf{7x = 21}} \\ { \sf{x = 3}}$

Then ky :

${ \sf{2ky = 3 - 5}} \\ { \sf{ky = - 1}}$

${ \bf{y = \frac{1}{2} }} \\ { \sf{ky = - 1}} \\ { \sf{k = - 2}}$

Pls help its was on khan academy i will mark u brainiest!!!

Phantasy [73]

Answer:

$14 units$

Step-by-step explanation:

$Solution:-$

$A(5,1)B(7,1)$

$\sqrt{(x_{1}-x_{2} ) ^{2}(y_{2} -y_{1}x^{2} }$

$AB=\sqrt{(7-5)^{2} +(1-1)^{2} }$

$= \sqrt{2^{2} } =2$

$BC=\sqrt{7-7^{2}+(6-1)^{2} }$

$=\sqrt{5^{2} } =5$

$perimeter=2(AB)+2(BC)$

$= 2(2)+2(5)\\$

$= 4+10= 14$

$-----------$

hope it helps...

have a great day!!
