Pi: Irrational
√(2/3): Irrational
0.57575757 is rational
and -1/2 is rational.
I hope this helps.
321 / 100 = 3.21 as you are dividing by 10, and then 10 again
Y= -6 --> plug this -6 into the y of the 2nd equation
y= 4x+12 --> -6 = 4x+12 --> 4x = -18
x = -18/4 = -9/2 --> now this is the x solution coordinate, and we know that y must equal -6 from the 1st equation, so our solution point is:
(-9/2, -6)
Hope that helped!
Answer:

Step-by-step explanation:
Required
The equation of the ellipse
This is calculated as:

Where:
---- height
--- width
So:



Answer:
x is less than or equal to 0
Step-by-step explanation:
- you need to multiply both sides of the inequality by 5/2
- then you reduce the numbers with the greatest common factor 5
- then you reduce the numbers with the greatest common factor 2
- any expression multiplied by 0 equals 0
- so you get x is less than or equal to 0
