IF ANYONE knows Imagine Math or has the site, Please help, she needs it and were trying to figure the questions....AGAIN please answer ASAP! :)
So if Lisa's reading list is 20% fiction, that's 20/100. So how can you simplify 20/100 so that the top number (the numerator) is 5?
If you divide both numbers by 4 (the same as dividing the fraction by 4), then you get 5/25. That means 5 out of 25 books are fiction. Her reading list is 25 books long.
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)
Step-by-step explanation:
its 3n+7
