Part A: It is a non-linear function because it doesn't continue at a constant rate. The last y value increased by 2 instead of 4 like the previous coordinates. There's no consistency if that makes sense.
Part B: linear- (1,2) (2,4), (3,6) Notice how the x increases by the same amount (1) and the y increases by the same amount (2)
non-linear- (2,4) (5,10) (7,11) The x and y values are increasing by completely different amounts in this one.
(x + 2y) ^2
(x + 2y) (x + 2y)
x^2 + 2xy + 2xy + 4y^2
= x^2 + 4xy + 4y^2
She is 24
24+2=26
26(1/2)=13
13+((24-3)1/3)
13+(21*1/3)
13+7=20
Therefore she is 24
900.000/90.000 is 10
Hope this helped!
Answer:
As square root of 9 can be written in the required form for being a rational number, so it is a rational number
Step-by-step explanation:
First of all we'll define rational numbers.
A number that can be written in the form p/q where p and q are integers and q≠0 is called a rational number.
Now we have to check if 
is rational or not, we will check if it can be written in the form p/q
As square root of 9 can be written in the required form for being a rational number, so it is a rational number
