How do you find the solution area to a system of inequalities? 100 points

larisa [96]

How To Solve Systems of Inequalities Graphically

1) Write the inequality in slope-intercept form or in the form

y

=

m

x

+

b

y=mx+b

.

For example, if asked to solve

x

+

y

≤

10

x+y≤10

, we first re-write as

y

≤

−

x

+

10

y≤−x+10

.

2) Temporarily exchange the given inequality symbol (in this case

≤

) for just equal symbol. In doing so, you can treat the inequality like an equation. BUT DO NOT forget to replace the equal symbol with the original inequality symbol at the END of the problem!

So,

y

≤

−

x

+

10

y≤−x+10

becomes

y

=

−

x

+

10

y=−x+10

for the moment.

3) Graph the line found in step 2. This will form the "boundary" of the inequality -- on one side of the line the condition will be true, on the other side it will not. Review how to graph a line here.

4) Revisit the inequality we found before as

y

≤

−

x

+

10

y≤−x+10

. Notice that it is true when y is less than or equal to. In step 3 we plotted the line (the equal-to case), so now we need to account for the less-than case. Since y is less than a particular value on the low-side of the axis, we will shade the region below the line to indicate that the inequality is true for all points below the line:

5) Verify. Plug in a point not on the line, like (0,0). Verify that the inequality holds. In this case, that means

0

≤

−

0

+

10

0≤−0+10

, which is clearly true. We have shaded the correct side of the line.

1.) The check number on a check:

ziro4ka [17]

Answer:

D) Identifies the transaction and is located at the top right corner of the check

Step-by-step explanation:

The check number on a check is the number located at the top right corner of the check, and it can also be found at the bottom of the check, located in lower right corner after the routing number and the account number

The check number aids in the tracking and identifying bank transactions such as to identify checks that the bank has processed and to know outstanding checks that are yet to be processed.

The check number also aids in balancing of the checkbook.

Therefore, the check number on a check identifies the transactions and is located at the top right corner of the check.

A health department spokesman speaking on a local radio station has advocated that parents download a particular app on their ph

maria [59]

Answer:

Option E is correct.

There seems to be a relationship between the app and preventing the spread of daycare illness.

Step-by-step explanation:

The study was carried out on a sample size of 1200 randomly selected parents and it was discovered that children of parents who downloaded the app, on average, had 10 fewer cases of daycare-related illness during the study period than those whose parents did not download the app.

Examining the options one at a time

a. Because downloading the app seems to decrease child illness, the app should be effective for decreasing child neglect as well.

The study showed that downloading the app seemed to truly decrease daycare-related illnesses in children, but it does not mention anything about child neglect. Hence, this is not a correct conclusion for the study.

b. Downloading the app will cause daycare workers to not spread germs.

The study did not in any way study how the app works, whether it prevents daycare workers to not spread germs, so, this conclusion seems like jumping the gun. It isn't an accurate conclusion of what the study did.

c. The study was an experiment rather than an observational study.

The study was actually more of an observational study. An observational study involves the researchers taking notes and recording the effects of a particular variable or lack of thereof, without interfering with the study.

d. The sample size of the study was too low to determine a result.

A sample size of about 1200 is a large enough sample for the sample characteristics to reflect the population characteristics. So, this statement too isn't true.

e. There seems to be a relationship between the app and preventing the spread of daycare illness.

Based on this information given, it is evident that the results of this study shows a relationship between the app. It shows a significant decrease in daycare-related illnesses in children of parents who downloaded the app. Hence, the app must have something that reduces the chances of a daycare-related illness in the children of parents who downloaded the app.

Hope this Helps!!!
