What is the equation of the graphed line written in standard form? 2x – y = –4 2x – y = 4 y = 2x – 4 y equals StartFraction one-

svp [43]

Answer:

The answer is "2x-y=4"

Step-by-step explanation:

Given:

$2x-y=-4\\2x-y=4\\y=2x-4\\y=\frac{1}{2}(x-4)\\$

The Formula of Slope:

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

by replacing the (2,0) and (0,-4) coordinates in the above formula:

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

if point y intercepting in x then x=0, for this the value of x= 0 and c=-4.

Equation of the line:

$\to y=mx+c$

apply m and c value in the above equation:

$\to y=2x-4\\$

Subtract by 2x on both sides of the equation we get:

$\to y-2x= 2x-4-2x\\\\\to y-2x=-4\\\\\boxed{\boxed{2x-y=4}}\\\\$

John cut a paper square with a perimeter of 18 inches into two rectangles. The perimeter of one of the rectangles is 10 inches.

koban [17]

Answer:

17 inches

Step-by-step explanation:

The original square had sides of 4.5 (18/4)

To get a perimeter of 10, we know that two sides would already equal 9 (4.5+4.5). That means we only have 1 inch for the other two sides, so they are each 1/2 inch.

That leaves the second rectangle with a length and width of 4.5 and 4.

2(4.5) + 2(4) =

9+8=

Find volume of this prism

attashe74 [19]

Answer:

324 km²

Step-by-step explanation:

The prism shown is a square pyramid

The volume of a square pyramid can be calculated by using this formula

$V=lw\frac{h}{3}$

where l = length of base, w = width of base and h = height

We are given the following dimensions...

length of base = 9 km

width of base = 9 km

height = 12 km

To find the volume of the pyramid, we plug in these given values into the formula

Hence,

$V = 9 * 9* \frac{12}{3} \\\frac{12}{3} =4\\V = 9*9*4\\9*9=81\\81*4=324\\$

V = 324
