Solve the system by substitution.<br> -8x - y = 30<br> -2y = x
masya89 [10]

Answer:

Solution:  (-4, 2),   x= -4 and  y =2

Step-by-step explanation:

-8x - y = 30

-2y = x

Substitute for x

-8*(-2y)   - y = 30

16y  - y = 30

15y = 30

y = 30/15 = 2

Then  x = -2y = -2*(2) = -4

Solution:  (-4, 2),   x= -4 and  y =2

Complete the square to factor X^2 +10X=-8
ella [17]

Answer: x=\sqrt{17}-5 and x = -\sqrt{17}-5

Step-by-step explanation:

Alright, lets get started.

The given equation is :

x^{2} +10x = -8

Adding 8 in both sides, it will become

x^{2} +10x + 8 = -8 +8

x^{2} +10x + 8 = 0

To make it perfect square, we need to add 25 and subtract 25

x^{2} +10x + 8 +25-25= 0

x^2+10x+25+8-25=0

(x+5)^2+8-25=0

(x+5)^2-17=0

Adding 17 in both sides  

(x+5)^2=17  

taking square root

x+5=\sqrt{17}

So,

x=\sqrt{17}-5 and x = -\sqrt{17}-5  .. Answer

Hope it will help :)
