Men's socks. Cost $8.00 for a package of three. How much would two dozen socks cost ?

weeeeeb [17]

1 dozen = 12

12 x 2 = 24

8/3 = x/24
3x=192
x=64

two dozen socks would cost $64

What is the equation of the graphed line written in

Andrew [12]

Given:

Given that the graph of the linear equation.

We need to determine the equation of the graph.

Slope:

The slope of the equation can be determined using the formula,

$m=\frac{y_2-y_1}{x_2-x_1}$

Let us substitute the coordinates (2,0) and (0,-4) in the above formula, we get;

$m=\frac{-4-0}{0-2}$

$m=\frac{-4}{-2}$

$m=2$

Thus, the slope of the equation is 2.

y - intercept:

The y - intercept of the equation is the value of y when x = 0.

Hence, from the graph, it is obvious that when x = 0, the value of y is -4.

Therefore, the value of the y - intercept is b = -4.

Equation of the line:

The equation of the line can be determined using the formula,

$y=mx+b$

Substituting the values, we have;

$y=2x-4$

Subtracting both sides by 2x, we have;

$-2x+y=-4$

Dividing both sides by -1, we get;

$2x-y=4$

Thus, the equation of the line is $2x-y=4$

Hence, Option B is the correct answer.

X2 – 7x + 6 = -8 solve using factoring

murzikaleks [220]

Answer:

Step-by-step explanation:

Rewrite this in standard quadratic equation form: x^2 - 7x + 6 + 8 = 0, or x^2 - 7x + 14 = 0. This does not factor easily, so I will use the quadratic formula to find the roots and then write out the factors based upon the roots:

The discriminant is b^2 - 4ac, which here is (-7)^2 - 4(1)(14) = -7.

Because the discriminant is negative, we know that there are two unequal, complex roots. They are:

-(-7) ± i√7 7 ± i√7

x = ----------------- = ---------------

2 2

One factor is (x - [1/2]{7 ± √7} )

X=8,2x+y=12 solve by substitution show work

son4ous [18]

$▪▪▪▪▪▪▪▪▪▪▪▪▪ {\huge\mathfrak{Answer}}▪▪▪▪▪▪▪▪▪▪▪▪▪▪$

Let's substitute the value of x as 8 in the given equation to find the value of y ~

$\sf2x + y = 12$

$\sf(2 \times 8) + y = 12$

$\sf16 + y = 12$

$\sf y = 12 - 16$

$\sf y = - 4$
