Answer: No it is <u>not</u> a solution
Why not? Because it doesn't make the first inequality true. Replace x with 1 and y with 2
y > 2x
y > 2*1 ... replaced x with 1
2 > 2*1 .... replaced y with 2
2 > 2 .... which is a false inequality statement since 2 is not larger than itself
Answer:
6
Step-by-step explanation:
The answer to number nine is 40
No, x²+y²= 9 does not represent y as a function of x.
For x= 0,
y²= 9
=>y= ±3,
i.e y has two values +3 and -3
Since single value of x , there are two values of y
For an equation or relation to be function every element in domain( every value of x) there should one distinct value or image in co-domain (one value of y)
