Answer:

I think its D)

7x−3y+2=0

Add -7x to both sides.

7x−3y+2+−7x=0+−7x

−3y+2=−7x

Add -2 to both sides.

−3y+2+−2=−7x+−2

−3y=−7x−2

Divide both sides by -3.

−3y /−3  =  −7x−2 /−3

which equals d)

Modern computers are built using the principle of Hierarchical layers of abstraction. Explain Hierarchical layers of abstraction
bearhunter [10]

Answer:

Hierarchical layers of abstraction in computers are used to hide information and manage deep functionality by allowing the separation to facilitate  platform independence.

Step-by-step explanation:

Hierarchical layers of abstraction in computers:

Hierarchical layers of abstraction in computers are used to hide information and manage deep functionality by allowing the separation to facilitate  platform independence.

In Hierarchical layers, users work independently at each level of the hierarchy.

example:

Abstraction in computing is language abstraction

Development of programming languages from machine language to  assembly language and then high-level language is an example of  Hierarchical layers of abstraction. Here each stage is a base for the next stage.

8x 1/4 how to simplify the radical expression
const2013 [10]
There are only two steps to solve this problem. 

The first step is to multiply the whole number (8) by the numerator (1). 8 times 1 equals 8, so 8 is our new numerator and our fraction should look like: 8/4.

The second step is to simplify it down even further. To do so, you need to figure our what multiples by 4 to get the answer of 8. 4 times what equals 8? The answer should be 2, since 4 times 2 multiples to 8.

The answer is: 2.
