An inequality is comparing the relation of two equations that are not equal.

Depending on a persons cell phone plan, if they can only talk for so many minutes per month or send so many texts per month, this is an inequality written as number of minutes/ texts per month needs to be less than or equal to the allowable amount.

x^2-4x-2=x-2\\\\x^2-4x-2-x+2=0\\\\x^2-5x=0\\\\x(x-5)=0\\\\x=0 \ or \  x-5=0

x=0 or x=5 

y = x - 2

Answer:

a. OM is congruent to ON.

Step-by-step explanation:

To use the HL Theorem, you must have a congruent hypotenuse and a congruent leg. In this case, you have two congruent hypotenuses. You just need to find two congruent legs.

a. OM is congruent to ON. This says that two legs are congruent, so this is your answer.

b. LM is congruent to ML. This does not help as it is saying a segment is the same as the same segment.

c. and d. Both of these use angle measurements, which does not help with the HL Theorem.

Hope this helps!

SOMEONE PLS HELP ME!!!!
STatiana [176]

Answer:

8. 6 shirts ($61)

9. $61

10. 32 shirts (256)

Step-by-step explanation:

To get the answers you could either graph the rates or create a table. Creating a table is easier to understand, graphing is much faster. I attached pictures of the graphs. Y axis being amount of $ and x axis being the amount of shirts.

Second graph is for questions 8 and 9

first graph for question 10

The difference is that i took out shipping for question 10

Table explains 8 and 9 more easily
