Answer:
False
Step-by-step explanation:
XY is the diameter of the circle with the centre of this circle being O.
But O on it's own is just a coordinate, and not the circle.
X - y = 9
x + 2y = 27
You can subtract the top equation from the bottom
3y = 18
y = 6
x = 15
The two numbers are 15 and 6
Answer:
t=0 and t=5
Step-by-step explanation:
5t = t^2
Subtract 5t from each side
5t-5t = t^2 -5t
0= t^2 -5t
Factor out a t
0= t(t-5)
Using the zero product property
t=0 and t-5 =0
t=0 and t-5+5=0+5
t=0 and t=5
Variables can be used to represent unknown numbers in a equation or expression that you will later find out what they are
Answer:
Well the divisibility rule for 22 is that the number must be divisible by 2 and 11. In order for something to be divisible by 2 it needs to end in 0, 2, 4, 6, or 8. For the number 11 the, if the difference between the odd numbered digits and the sum of the even numbered digits is a multiple of 11 then it is divisible by 11.
So I would say no for both of them since 22 is divisible by 11.
Please let me know if I'm wrong.
