Answer:
x² + y² = 4
Step-by-step explanation:
The equation of a circle centred at the origin is
x² + y² = r² ← r is the radius]Here r = 2, thus
x² + y² = 4
Answer:
This is a ratio table,so therefore there is always a pattern.
Step-by-step explanation:
In order to solve,you have to find the constant in the question,such as 30,40,50,and 60.The constant in this example is 10.When the constant is <u>not</u> even,or the numbers are <u>not</u> even,that's the time you pull out your notebook multiplication chart.Look at the numbers,and see if those numbers are on the chart.If all of them are on the chart,then see if one or both of the multiplicable numbers fall under the category of your variables.If all are under one number,then that number is your answer.
Answer:
C
Step-by-step explanation:
first look at all the numbers in the relation.then since inverse means opposite find the answers where the numbers in the parenthesis are in the opposite order than the question. Finally look for the answer In which all the positive numbers in the parenthesis(in the given relation) are negative (on the answers)and the negative numbers (in the given relation) are positive (on the answers).
