3x^2 + 3y^2 = 75
Dividing through by 3 we get
x^2 + y^2 = 25
The center is at (0,0) answer
Answer: Angle 10 and Angle 2
Answer: 5/4, or 1.25
Step-by-step explanation:
To solve, get a variable on one side. First, add 5 on both sides.
g(x) = 4x-5+5
Next, divide by four.
5/4 = 4x/4
Now, solve.
5/4, or 1.25 = x
One tenth of 200 is 1/10 x 200 = 200/10 = 20
20 is your answer.
Answer: 63 < N ≤ 66
Step-by-step explanation:
We have the set:
(66, 64, 65, 66]
First.
When we have an end with the signs "(" or ")" means that the element near the sign does not belong to the set, this would be an "open" end. Usually used for the symbols > and <
While the sign "[" or "]" (in some cases the symbols { and } are used instead)
means that the value next to it are included in the set. Usually used for the symbols ≤ and ≥.
Then in the set: (63, 64, 65, 66} the value 63 does not actually belong, and value 66 does belong.
Then this set is written as:
63 < N ≤ 66
Such that N is an integer number.
