What is the equation of the line passing through the points  (Two-fifths, StartFraction 19 Over 20 EndFraction)and  (one-third,
Vinil7 [7]
<h3>4x - 8y = -6 is the equation of line in standard form</h3>

<em><u>Solution:</u></em>

<em><u>The equation of line in point slope form is given as:</u></em>

y - y_1 = m(x-x_1)

Where, m is the slope of line

<em><u>The slope of line is given as:</u></em>

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

From given,

(x_1, y_1) = (\frac{2}{5} , \frac{19}{20})\\\\(x_2, y_2) = (\frac{1}{3} , \frac{11}{12})

<em><u>Substituting the values we get,</u></em>

m = \frac{\frac{11}{12} - \frac{19}{20}}{\frac{1}{3} - \frac{2}{5}}\\\\Simplify\\\\m = \frac{-8}{240} \times \frac{15}{-1}\\\\ m = \frac{120}{240}\\\\m = \frac{1}{2}

\text{Substitute } m = \frac{1}{2} \text{ and } (x_1, y_1) = (\frac{2}{5} , \frac{19}{20}) \text{ in eqn 1 }

y - \frac{19}{20} = \frac{1}{2}(x - \frac{2}{5})\\\\y - \frac{19}{20} = \frac{x}{2} - \frac{1}{5}\\\\\frac{x}{2} - y = - \frac{19}{20} + \frac{1}{5}\\\\\frac{x}{2} - y = \frac{-15}{20}\\\\Simplify\\\\y = \frac{1}{2}x + \frac{3}{4}

In standard form,

y = \frac{4x+6}{8}\\\\8y = 4x + 6\\\\4x - 8y = -6

Thus the equation of line is found

The area of a rectangle is the product of its length and width .Suppose the area of a rectangle is 24 in 2.What are the possible
agasfer [191]
The area is 24 square inches.  So its dimensions in inches
must be factor-pairs of 24 .

Those are

1 x 24
2 x 12
3 x 8
or
4 x 6 .

Which expression is equivalent to 8?<br><br><br> -48 ÷ 6<br> 48 ÷ (-6)<br> 48 ÷ 6<br> -48 ÷ (-6)
V125BC [204]
Expression 3, 
because 6 and 8 are factors of 48. Since positive 6 & 8 are the two numbers of choice, the product will be positive. My answer is reasonable because if you were to multiply positive 8 and 6 you will get positive 48.

What function is f(x)=x
Oxana [17]
A function assigns exactly one output to each input of a specified type. It is common to name a function either f(x) or g(x) instead of y. f(2) means that we should find the value of our function when x equals 2. f(x) is the value of the function.

I’ve gotten this answer wrong twice already
sattari [20]

Answer:

Step-by-step explanation:

The standard vertex form of a quadratic (which is what your graphs are) is

y=(x-h)^2+k where h and  are the coordinates of the vertex. The vertex is really all we need to fill in this equation. Looking at the blue graph, the vertex is located at (-4, 1), so h = -4 and k = 1. Filling in the equation:

y=(x-(-4))^2+1 which simplifies down to

y=(x+4)^2+1. It's that simple.I think that's choice C (I'm not sure; it's very tiny!)
