Which set of coordinates satisfies the system of equations y = x − 3 and y = -2x + 1?

The right option is C

Explanation: The equations that we have are:

y = x-3

y = -2x + 1

to solve this, we can remove one of the variables in one of the equations; we know that y = x- 3 and y = -2x + 1, so we must have:

x - 3 = -2x + 1

and we can solve it for x:

3x = 1 + 3 = 4

x = 4/3

Now we replace this value in the first equation:

y = 4/3 - 3 = -5/3

So the pair is: (4/3, -5/3), and the right option is C.

which sentence correctly states the function of a control unit?

john was teaching his students about the basics of computer hardware and software. by the end of his lecture, he asked his class to state the basic function that a computer’s control unit performs. four students answered gave four different answers. george said that a control unit performs arithmetical and logical computations. alex mentioned that it stores the data for computations. helen stated that it coordinates the flow of instructions and data within computers. lastly, myron suggested that it displays results of computations.
