Answer:

The equation of the line passing through the points (-2,0) and (0,-4)

$\frac{y - y1}{x - x1} = \frac{y2 - y1}{x2 - x1}$

$\frac{y - 0}{x - ( - 2)} = \frac{ - 4 - 0}{0 - ( - 2)} = \frac{ - 4}{2} = - 2$

$y = - 2(x + 2) \\ y = - 2x - 4$

$2x + y = - 4$

The equation of the line passing through the points (0,-2) and (4,0)

$\frac{y - y1}{x - x1} = \frac{y2 - y1}{x2 - x1} \:$

$\frac{y - ( - 2)}{x - 0} = \frac{0 - ( - 2)}{4 - 0}$

$\frac{y + 2}{x} = \frac{1}{2}$

$x - 2y = 4$

Option B

x minus 2 y = 4 and 2 x + y = negative 4

Question 19 Only, Please show your work. Solve the problem.

ankoles [38]

Answer:

$5\sqrt{2}$

Step-by-step explanation:

Draw a diagonal (line segment from one corner to the opposite corner). You'll form two right triangles with the diagonal being the hypotenuse of both triangles.

Use the Pythagorean Theorem: (leg)^2 + (leg)^2 = (hypotenuse)^2.

Let h represent the length of the hypotenuse.

$h^2 = 5^2+5^2\\h^2=25 + 25\\h^2 =50\\h=\sqrt{50}\\h=5\sqrt{2}$

The question is just a bit vague. It should say opposite corners. I'm assuming the question does not mean the length of one side!

An author released his book on May 1. His daily sales steadily increased until they peaked and then steadily declined. He found

dem82 [27]

The domain of a certain function are all possible values of x that are applicable to the function or can make the function true. For this certain function, the domain is from the time that the book was released to the time that the sales was also zero due to steady decline in sales.

Angle $eab$ is a right angle, and $be = 9$ units. what is the number of square units in the sum of the areas of the two squares

Alla [95]

Let the measure of side AB be x, then, the measue of side AE is given by

$AE=\sqrt{9^2-x^2}$ .

Now, ABCD is a square of size x, thus the area of square ABCD is given by

$Area=x^2$

Also, AEFG is a square of size $\sqrt{9^2-x^2}$ , thus, the area of square AEFG is given by

$Area=\left(\sqrt{9^2-x^2}\right)^2=9^2-x^2=81-x^2$

The sum of the areas of the two squares ABCD and AEFG is given by

$x^2+81-x^2=81$

Therefore, the number of square units in the sum of the areas of the two squares ABCD and AEFG is 81 square units.
