Which is true regarding the system of equations? x minus 4 y = 1. 5 x minus 20 y = 4. The system results in a false statement. The system results in an intersection at one point. The system results in many solutions because they are the same line. The system results in a true statement.

The system results in a false statement.

Step-by-step explanation:

Let's actually solve the system

x-4y=1 (1)

5x-20y=4 (2)

Using the elimination method

Eliminate y by multiplying equ (1) by -5

We have,

-5x + 20y = -5 (3)

Add equ (3) and (2)

-5x + 20y = -5

5x -  20y =  4

 0   = -1

The system results in a false statement.

Step-by-step explanation:

If cost is directly proportional to speed, then the equation for this is

£ = ks, where k is the constant of proportionality. We need to solve for this first.

400 = k4 so

100 = k. Now we will use that k value in the next equation to find the cost of a 6GHz processor:

£ = (100)(6) so

£ = 600
