Answer:

6±√10

Step-by-step explanation:

x^2-12x+26=0

x= ± √10  +6

6±√10

The solutions of the given quadratic equation  [tex]x^2 - 12x + 26 = 0[/tex] are;

x = 6 + √10 and x = 6 - √10.

To solve the quadratic equation [tex]x^2 - 12x + 26 = 0[/tex]

using completing the square method, follow the steps below.

Move the constant term to the right side of the equation

[tex]x^2 - 12x = -26[/tex]

To find the value that completes the square, divide the coefficient of x by 2 and square it.

[tex](-12/2)^2 = 36[/tex]

Add and subtract the value obtained in step 2 to the left side of the equation

[tex]x^2 - 12x + 36 - 36 = -26[/tex]

Simplify the left side of the equation by factoring the perfect square trinomial

[tex](x - 6)^2 - 36 = -26[/tex]

Add 36 to both sides of the equation to isolate the perfect square trinomial

[tex](x - 6)^2 = 10[/tex]

To Take the square root of both sides of the equation

x - 6 = ±√10

Solve for x

x = 6 ± √10

So, the solutions of the given quadratic equation  [tex]x^2 - 12x + 26 = 0[/tex] are x = 6 + √10 and x = 6 - √10.

Step-by-step explanation:

Answer:

y-1 = 5(x+8)

Step-by-step explanation:

The standard equation of a line in point slope form is expressed as;

y-y0 = m(x-x0)

m is the slope

(x0, y0) is the point

Given

Slope m = 5 (assumed value)

Point (-8,1)

Substitute the given data's into the formula

y -1 = 5(x-(-8))

y-1 = 5(x+8)

Hence the required equation is y-1 = 5(x+8)

Answer:

A

Step-by-step explanation:

Given the inequality, y > -½, the graph that represents this would have a directed line starting from -½ and pointing to your right. It would also have an unshaded circle, or empty circle, signifying that -½ is not included among the set of possible values of y.

Thus, the right graph would be graph A.

Answer:

No because of the 3xy term. For an equation to be considered linear there has to be one y value for every x value given

The answer is 3xy + 8 = 4y  is not a linear equation.

Linear equations help in representing the relationship between variables such as x, y, and z, and are expressed in exponents of one degree. In these linear equations, we use algebra, starting from the basics such as the addition and subtraction of algebraic expressions.

Given here: 3xy + 8 = 4y

The degree of this equation is 2 and thus the graph of this equation is not linear.

Hence, 3xy + 8 = 4y  is not a linear equation

Answer:

BC = 8

Step-by-step explanation:

AB + BC = AC

4x + 8 + 3x - 4 = 32

7x + 4 = 32

7x = 32 - 4

7x = 28

x = 28/7

x = 4

BC = 3x - 4 = 3*4 - 4 = 12 - 4 = 8

Answer:

B) 8

Step-by-step explanation:

The Segment Addition Postulate basically states that the sum of the segments of a line will equal the length of the entire line.

Thus, AB+BC=AC, and we can substitute:

AB+BC=AC

(4x+8)+(3x-4)=32

4x+8+3x-4=32

7x+4=32

7x=28

x=4

Now that we have x, we can plug it in for segment BC:

BC=3x-4

3(4)-4

12-4

Step-by-step explanation:

Take 25% of 60 and that is 15. Please give me brainliest

Answer:

$45.00

Step-by-step explanation:

To find percentage, most start out by dividing the percent by 100:

25 ÷ 100 = 0.25

Then, to find the percentage of 60, we multiply them.

$60 x 0.25 = $15

15 is 25% of 60. However, we're asking the sale price of the video game, not the amount it was reduced. To find this out we subtract the reduced amount from the original number:

$60 - $15 = $45

Answer:  

X + Y = 5.678

X - Y = 9.876

The two numbers: X = 7.777   Y = -2.099

Step-by-step explanation: solve by elimination

X + Y = 5.678

X - Y = 9.876 . Add the two equations so the y cancels. Solve for x

2x = 15.554 .  Divide both sides by 2

X = 7.777    Substitute in the original equations to find Y

7.777 + y = 5.678 . Subtract 7.777 from both sides

Y = - 2.099

check in the second equation:

7.777 -(-2.099) = 9.876

7.777 + 2.099 = 9.876 True

The two numbers is X = 7.777 and Y = -2.099.

And, the two equation is X + Y = 5.678  and X - Y = 9.876.

Given that,

Based on the above information, the calculation is as follows:

X + Y = 5.678

X - Y = 9.876

2x = 15.554  

X = 7.777    

Now  

7.777 + Y = 5.678  

Y = - 2.099

Therefore, the above should be the answers.
