2y = 10
y = 10/2
y = 5 <==horizontal

this is a horizontal line. Anytime you have y = an integer, it is horizontal...and if u have x = an integer, it is a vertical line.

Answer:

2y = 10 is horizontal line.

Step-by-step explanation:

 Given : The equation 2y = 10

We have to choose from the given options that correctly describes the line 2y = 10

Consider the given equation of line 2y = 10

Divide both side by 2 , we have,

y = 5

Since, y = 5 is a line parallel to x - axis

Thus, 2y = 10 is horizontal line.

Was the variable "y" supposed to be part of this equation?  If so, perhaps you meant to share the following:

<span>   0.24x − 1.85y = 3.09
− 2.33x  = 1.71y

Plese, go back and reread the original question, and then ensure you have shared that question here precisely as it was presented.</span>

The LCM of three numbers is 7920 and their GCD is 12. Two of the numbers are 48 and 264. Using factor notation find the third nu
12345 [234]

Answer:

The third number is 180.

Step-by-step explanation:

Let the third number be 9x where x is an integer.

48 = 2*2*2*2*3

264 = 2*2*2*3*11

9x = 3*3*x

2*2*2*2*3*3*11*x = 7920y where y is an integer

1584x = 7920y

so x = 7920y / 1584= 5y.

Now the GCD is 12  so x must have  4 as one of its factors.

Also x is a multiple of 5 so it could be 20 then y  would be 4.

If x = 20 then the third number is 9*20 = 180.

This checks out OK.

Use completing the square to solve for x in the equation (x minus 12) (x + 4) = 9. x = –1 or 15 x = 1 or 7 x = 4 plus-or-minus S
Scrat [10]

Answer:

x = 4 ± \sqrt{73}

Step-by-step explanation:

Given

(x - 12)(x + 4) = 9 ← expand the left side using FOIL

x² - 8x - 48 = 9 ( ad 48 to both sides )

x² - 8x = 57

To complete the square

add ( half the coefficient of the x- term )² to both sides

x² + 2(- 4)x + 16 = 57 + 16

(x - 4)² = 73 ( take the square root of both sides )

x - 4 = ± \sqrt{73} ( add 4 to both sides )

x = 4 ± \sqrt{73}
