If ajay has x dollars and his sister manisha has one-half as many, express algebracially the number of dollars manisha has?

Manisha has x/2 dollars.

Step-by-step explanation:

ajay = x

manisha = half of x     -->    manisha = x/2

the square root of what number? if you add that, then someone will probably answer the question.

check above link.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.
