Which equation can pair with 3x + 4y = 8 to create a consistent and independent system?

Answers

There isn't any choices given in this problem but I can give you a tip to answer these kinds of problem. When you say independent, it means that the equation cannot be algebraically altered to result to 3x + 4y = 8. So the equation 6x + 8y = 16 is not an independent equation since when you divide each side by 2 it will result to 3x + 4y =8. You get the idea. 

Answer:

6x - 3y = 2

Answer:

4 times 10 to the negative seventh power

Step-by-step explanation:

We can see that the decimal has 6 zeros before it, and then it’s 4.

since there are 7 digits after the decimal point, we put 10 to the negative seventh power.

that gives us 0.0000001

to get 0.0000004, we need to multiply ten to the negative seventh power (0.0000001) by 4

The answer is a. which is 4 x 10‐⁷

If the exterior angle of a regular polygon equals 120 degrees what is the shape is the polygon

Answers

It is a triangle, because the sum of the exterior angles is always 360. We need to find a natural number n, such that 360/n=120. Of course n is 3 which means there are 3 angles. Three angles means 3 sides so it is a triangle! Or triangular.
