Which graph represents the solution set of the system of inequalities?

{−2x+y≤4y> x+2

The fourth graph is the answer

Explanation:

We have inequalities

For the first inequality all points at or below the graph of y are solutions, and for the second inequality all the points above the graph of y are the solutions. So, the solution to these inequalities are points that are above the graph of and below the graph of . The shaded region in the fourth graph satisfies these conditions.

Looking at other choices, we see that the first two graphs do not even represent the graphs of our inequalities, and the third graph does represent the inequalities but shades the wrong region.

P.S: the graph of the inequality  is dashed because   is "greater than" and not "equal to" , so this indicates that the values on the line are not included. And the graph of the inequality is a solid line because is "less than or equal to" , so we are including the values on the line , and that's why it's solid.

weight of the box is given as

here this is placed on the inclined of angle 42 degree

now this weight will have two components one is along the incline other is perpendicular to it

so here we need to apply a force parallel to incline opposite to its component of weight

so here the component of weight is given as

here we have

so it requires 75 n force to move it upwards
