After graphing both lines, we're able to tell the solution by looking at the point where the lines cross. In this case, it's at (4, -1). And so that is the solution set.

How might this number be shown on a calculator?<br> 5.31x1037 (37 is above 10)<br> [?]e[ ]
Arisa [49]

Answer:

5.31E37

Step-by-step explanation:

Given

5.31 * 10^{37}

Required

How it'd be displayed on a calculator

Standard calculators, today are built to always convert huge numbers or extremely small number to scientific notations;

This was done to allow the calculator fit each values on its screen

5.31 * 10^{37} is such a big number that it'll require the calculator to display it using scientific notations;

So, basically we have to convert 5.31 * 10^{37} to scientific notaton;

This is achieved by replacing *10^{37} with E37

So, 5.31 * 10^{37} is equivalent to 5.31E37

Which ordered pairs are in the solution set of the system of linear inequalities? y &gt; x y &lt; x + 1 (5, –2), (3, 1), (–4, 2)
steposvetlana [31]

To check which ordered pair (point) is in the solution set of the system of given linear inequalities y>x, y<x+1; we just need to plug given points into both inequalities and check if that point satisfies both inequalities or not. If any point satisfies both inequalities then that point will be in solution.

I will show you calculation for (5,-2)

plug into y>x

-2>5

which is clearly false.

plug into y<x+1

-2<5+1

or -2<6

which is also false.

hence (5,-2) is not in the solution.

Same way if you test all the given points then you will find that none of the given points are satisfying both inequalities.

Hence answer will be "No Solution from given choices".
