The first equation in a system is 5x + 2y = –4. Which equation gives a system with no solution? A. y = 2x + 6 B. y = 1/4x – 2 C. y = 2x + 7 D. y = –5/2x – 3

Given:

The first equation of the system of equations is

To find:

The equation that gives a system with no solution.

Solution:

We have,

It can be written as

On comparing this equation with slope intercept form , we get

It means the slope of the line is and the y-intercept is -2.

Slope of parallel lines are same but the y-intercepts are different.

From the given options, the slope of the line is only in option D and the y-intercept is -3 which is different from -2.

The line is parallel to the given line and parallel lines have no solution. So, the second equation of the system of equations is .

Therefore, the correct option is D.

could you reply to this with the question so i can ?

company a

step-by-step explanation:

using the linear regression models , it is found that company a   pays about $14 more. but using the same regression (linear) company b pays about $10 more.

so company a pays more than b
