Using a Graphing Utility, use the matrix capabilities of a graphing utility to write the augmented matrix corresponding to the system of equations in reduced row-echelon form. Then solve the system.
$$\left\{\begin{aligned} x+2 y+2 z+4 w=& 11 \\ 3 x+6 y+5 z+12 w=& 30 \\ x+3 y-3 z+2 w=&-5 \\ 6 x-y-z+\quad w=&-9 \end{aligned}\right.$$

Just get in the graph. Inner. Any question we need. DuPont's off the underline. So we used the X and Y into seven. Now for the X in this app we're trying to send a wiII Coaches are They're focusing and 1/2. Thanks. We got your 600. It means down the X We iko do 1200 something from the, uh Why in the sap we need to send Thanks. Seiko Jews are, uh, their phone under minus 100 tree. Why? He called you 600. Their founder. Why? Equal to minus one doesn't handwrite. And now this one. Me in last. None of us bonus 1200 zero and isn't English. Then we should have this second ponies there. Minus 1000 and 800. Now we should be able to sketch it now. So we have the first point is 1200 here. So 600 what is the General will be here. Ah, 600 wonder. I want to degenerate while toes on internet here. So if you need to turn the Jew Pons Joe Randa So this one will be 1200 Businessman is 1800

We have a system of equations. We have to solve this with the help of reduced raw clone form. For that first we have to write the augmented metrics, which here is to 10, 26 15 26 151 three minus three minus 15 minus three minus nine. This is our open ended metrics. We have to find the reduced heroically on form, but the help off metrics calculator. So I've entered the metrics here and we can find the reduced radically inform using the function. Onda. We have obtained it as 1500 Cyril one three and all the remaining are zeros here. Right? So this is a reduced role. Clear. Inform. So using this, we can write Rewrite the creation says X plus five by equals zero and that equals three. So it's that bigger. That's three and we have only one relation connecting extend by. So if by equal, do it any number eight Any real number then X equals minus five times it. So the solution can be written us minus five way he three. This is a required solution. This is a

So we have a salesperson receiving a monthly salary of $2,000 Um and 7% Commission on sales. And then we're offered a new job for $2300 per month with a 5% commission sales. So we want to look at the two different wages. So we'll have w equals 2000 is the initial class 7%. So it's your .07 times the s. Sales. So that's what we end up having here for our graph. And then the other option is a way of $2300 with only 5% commission. So we see that um with these two, we want to find the point of intersection. So that tells us that at $15,000 worth of sales Um will break even at $3,050. Mhm. So if we can sell $20,000 worth of product, we should not change jobs.

Yeah. In this problem of frequency distribution, we have to construct our expanded frequency distribution table on the frequencies to run for the food asset using indicate number of classes. So here the number of classes given us six. Look. Yeah, it's Yeah. Yeah. So now, using the data we can find out class with Yeah, Yeah, which is equal to the range. Divided by number off clauses. So the range will be maximum value. There is 7119 mamas, thousands or 7119 minutes 1000. 6000 119 divided by six. Yeah, you, Which is eat welcome. 2000. Yeah, yeah, yeah. Information, which is equal 2000 and 20 approximately. So now we can construct the class column. Mhm. Oh, so it starts with 1000 and mhm. Mhm. Yeah. Okay. Okay. Thinking Yeah, yeah, yes. Yeah. So And ends with 1000 place. 1020. So since the classes do not overlap, will be 1000 plus 1019. So it was 2000 and 19 in 2000 and 20. Okay. 2 3000 and 39. No, 3000 and 14. Yeah, to 4000 59. Yeah, 4060? Uh huh. 5079. 5000. 80 6099. 6100. Okay. To 7000. 119. You know the frequency. Okay. You know. Yeah. Yep. Became just fine on the table. So 1000 and 19 2001? Yeah. Okay. 23 Yeah. 456 789 Okay, 10, 11, 12. Yeah. 2022 to 3039. Will be one to three ever. 3000. 40. Mhm. 2059. No. Yeah. Being one. You, too. 4062. 5079. Yeah. 12 Yeah. Beautiful. In three. 5018. About 6089. It is one, just one. And the last class will be just one value. Now we can find the midpoint. That's not really midpoint. We know that. Lower class limitless upper class limit by two. Look. So here it ISS 1000 plus 19 2005. 2 weeks 1005 195.5. 2005. 29.5. 3000 5. 49.5 all. We can just start 1,002,020 to the PBS midpoint. 4000 5. 69.5. 5000 I 5. 89.5. 6000. Maybe 609.5. So summation F Z equal toe the sample size, which is frequent 22 years. Now we have to find the later frequency. Yeah, yeah, yeah. Okay, So related frequency is nothing but the class frequency divided by a dog. Sample size increased class frequency. Yeah, help you. So that could be 12 by Okay, 22. Hi. 0.5455 three Bites. Okay. Yeah. 22 which is 0.1364 e. Yeah. Good to buy 22 just Yeah. 0.909 and three by 20 to 0.1364 one by 22. Yeah. 0.45 four. Yeah, never enough. You know, if we had this? Yeah. Yeah, she said right. This is equal into solution. E no. Right. Yeah, I if I am, is equal to one. Now we have to find accumulator frequency. Yeah. Yeah. Simulated frequency is nothing but some off current frequency placed all the previous frequencies. So for the first frequency is just well, once again just request 12. 15 and third with the 32 plus three plus well, which is 17. Similarly, this one will be 17 plus 3. 20 the next 21 What? 22 which is the same precise. No, we have to find you have to. Prince Crypto frequencies took them right. Mhm, right? Yeah. And this is the Mr Graham representing who? Stable, which has the class. That is a July sales in order the horizontal axes, July sales in dollars and is the frequency. So for the first class, off mid points, you are all these on the points. These are the frequency. It's 12 if we see tallies without frequency distribution table. Now, if you see the trend of the car pattern, you see most of the sales of between 1000 2000 and 19 to it. Most of the sales between 1000 in 2000 and 19. Sure,
