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 :)

In the coordinate plane, what is the length of the line segment that connects points at (4, −1) and (9, 7) ? Enter your answer i
andreev551 [17]
On this question is asked you to find the length of a line segment with endpoints (4,-1) and (9,7) and round it to the nearest hundredth. The only way to find the solution is by the use of the Distance Formula, which is d=√(x2-x1)^2+(y2-y1)^2.

<span>d=√(x2-x1)^2+(y2-y1)2^2
</span>d=<span>√(9-4)^2+(7--1)^2
d=</span><span>√(5)^2+(8)^2

Which equation, in point-slope form, represents a line with m= -4/7 that goes through the point (-1, 4)?
Gelneren [198K]
A is the correct answer.

Point Slope Form: y - y₁ = m(x - x₁)

m = slope ⇒ -4/7
Coordinate: (-1  ,  4)
                       x₁    y₁

All you have to do is plug in all of the information above into the formula.

y - 4 = -4/7(x +1)

IF S.P. = Rs 1,869, loss percent = 11% find C.P.​
Veseljchak [2.6K]

Here,

Selling Price (S.P) = Rs 1869

Loss = 11%

Cost Price (C.P) = ?

Let, C.P be x

Now,

Sp = Cp - loss% of Cp

1869 = x - 11/100*x

1869 = (100x - 11x)/100

186900 = 89x

◆ x = Rs 2100

Cp = Rs 2100

I hope you understand...

It's a Right answer...

Thanks♥♥
