Mathematics
1 answer:
Zanzabum3 years ago
6 0

Answer:

C; None of the above.

Step-by-step explanation:

Pretend x=1, y=0, and z=2.

You have to match an answer to 1+0-2 (equals to -1).

The first equation would be 2+0+1. When you add them all together you get 3, and that isn't equivalent to -1, so therefore this one is not the answer.

The second equation becomes 1+2+0, and when you solve for the answer, you see that the answer is also 3, and so we can conclude that neither A or B matches with the equation above, so the answer is C, None of the above.

What is the area, in square units, of the polygon shown here?
Molodets [167]

The area of a 2D form is the amount of space within its perimeter. The correct option is D.

<h3>What is an area?</h3>

The area of a 2D form is the amount of space within its perimeter. It is measured in square units such as cm², m², and so on. To find the area of a square formula or another quadrilateral, multiply its length by its width.

The area of the L block will be the sum of the area of A and B. Therefore, the area can be written as,

Area of L block = Area of A + Area of B

                          = (7×2) units² + (1 × 5) units²

                          = 14units² + 5units²

                          = 19units²

Hence, the correct option is D.

Given the Standard Form of linear equation 5x - 2y = 10, find its x-intercept and y-intercept: (show your work)
Rzqust [24]
We have that
5x - 2y = 10

we know that

Part A)
the x-intercept is when y=0
then
5x - 2y = 10------> 5x=10--------> x=10/5------> x=2

the answer Part A) is
the x intercept is the point (2,0)

Part B)
the y-intercept is when x=0
then
5x - 2y = 10------> -2y=10------> y=-10/2-----> y=-5

the answer Part B) is
the y intercept is the point (0,-5)

see the attached figure
