Answer: (-infinity,10]
Step-by-step explanation: 50n is less than or equal to 500. So, treat the less than or equal to sign as an equal sign. Then do like regular and divide 500 by 50 to get ten on the right while N stays on the left. To get n is greater than or equal to 10!
Answer:
2) -1
Step-by-step explanation:
it is easy
we have to first open the brackets, as it is ' - ' we have to change the sign to opposite of that of the number in the bracket and then solve it.
so the number 2 is having negative sign, we make it positive. this rule is applied only when there is a negative sign and a bracket is there.
-3-(-2)
-3+2
=-1
Answer:
The answer is "Option C"
Step-by-step explanation:
- It is the hypothesis which would be opposed to just the null hypothesis, that is used in its testing.
- In this, we generally believed that the results derive from a particular effect with some superimposed variance of chance.
- It is nothing but an option in contrast to the null and its original test starts by considering its two hypotheses, that's why the only option C is correct.
Jane is given a $100 gift to start and saves $35 a month from her allowance.
After 1 month, Jane has saved
After 2 months, Jane has saved
After three months, Jane has saved
and so on
In general, after x months Jane has saved
This means that it makes sense to represent the relationship between the amount saved and the number of months with one constant rate (in this case the constant rate is 35). It makes sense because the amount of money increases by $35 each month. Since the amount of increase is constant, we get constant rate. Also the initial amount is known ($100), so there is a possibility to write the equation of linear function representing this situation.
Step-by-step explanation:
In this question, angle 5 and angle 2 are linear pair. And angles of linear pair are supplementary angles .
Therefore

And sum of interior angles of a triangle is 180 degree, that is

SInce both the equations have 180 in the right side, left side of both equations are equal too . That is

Which gives

So the correct option is A .
